Marselisborg ReWater | Business Card Catalouge 5 INTRODUCTION “SPEED DATING” with Aarhus Vand

This catalog offers an overview of the players we went on a Research in basic technologies “speed date” with from April to June 2017 in connection with the Innovation through the use and combination of new technologies development of Marselisborg Resource Plant, a.k.a. Marselisborg Development through the combination of well-known technologies Rewater. for new solutions Maturation through the use of well-known technologies and The invitation to participate in the “speed dating” was introduced adaptation to Marselisborg Rewater at a ‘kick-off’ event in Aarhus on 28 March 2017. We set forth 15 innovation challenges to be solved together with companies, The 15 innovation challenges are further described in the innovation producers, suppliers, research institutions, entrepreneurs and strategy for Marselisborg Rewater, which can be found on www. others capable of combining professional insight and innovation so aarhusvand.dk/rewater that we can open the doors to the world’s most resource-efficient wastewater treatment plant in 2026. The list of players and the solutions they suggest mark the beginning of the process of developing the new Marselisborg Rewater. 40 players accepted the offer to go on a preliminary “speed date” The dialog on the technical challenges and the other innovation with us to find out if there was a perfect match for cooperation. All challenges will continue with the potential partners. “speed dates” centered around two questions: “How can you help address one or more of the described innovation challenges?” and This catalog was an attempt to develop an “extended business “What do you expect to achieve by cooperating with Aarhus Vand card” with the players we met and their (initial) thoughts about how (and/or other players) on this project?” to rise to the innovation challenges. This should hopefully ensure an open process – for those who participated in the “speed dates” The “speed date” invitation was open to all interested companies, as well as other interested parties. knowledge and research institutions, and organizations able to combine professional insight and innovation. The “business cards” were designed based on the individual player’s own written feedback within the framework of the template. The Rethinking, developing and building tomorrow’s wastewater order represents the order in which the “speed dates” took place, treatment plant is a long process. That is why we have initially and the solutions presented should be regarded as proposals/ sought solutions and partners for the technical challenges (see inspiration only. #2-9 and #11) based on:

6 Marselisborg Ressourceanlæg | Visitkort katalog The summary table on pages 10-11 lists the innovation challenges the players had indicated that they would like to respond to ahead of their individual “speed date”. The focus was on the technical challenges; however, since more of the players may also contribute to overcoming the other challenges, they have also been included in the table.

Following the “speed dates”, Aarhus Vand, together with Smith Innovation, added extra innovation challenges for players with a possible match. This is also indicated in the table. A player’s input to innovation challenges subsequently added by Aarhus Vand does not necessarily appear from the player’s own response.

At the end of the catalog, there is an outline of how we will use the many inputs in the concrete resolution to the innovation challenges.

TechRas Miljø specializes in the supply of separation solutions, technical equipment and turnkey solutions in processing, filtering and pre-drainage and final drainage of wastewater. TechRas Miljø offers a number of world- patented processes such as S::Select and DEMON, as well as professional advice on process optimization.

www.techras.dk

Contact: Frank Rasmussen, Director, [email protected]

Contribution to addressing the innovation challenges

TechRas Miljø is already an established business partner of Aarhus Vand’s, and we want to help overcome the innovation challenges of developing Marselisborg ReWater in the following areas:

• Pre-separation of primary sludge by means of Mecana filters. This is tested at Marselisborg Wastewater Treatment Plant in the summer of 2017. • Effluent polishing by means of Mecana filters (ready for the removal of microplastics). In 2016, tests were conducted at Viby WWTP replacing sand filters by Mecana filters, and experience from other plants in Europe is positive. Microplastics can be removed easily and effectively by means of Mecana filters during polishing. However, the concentration of the rinse water from the filter is an issue that remains to be examined, but we do have some ideas already. • Optimization of the biological process through S::Select and DEMON processes. The S:: Select process is a world-patented process that can reduce the necessary volume of the biological tanks and the final consolidation tanks by 40-50%. Aarhus Vand already has good experience with the DEMON process for the treatment of reject water from the final drainage. • Pre-draining by means of a decanting centrifuge. This gives a 50-70% reduction in polymer consumption and disintegration of the sludge, which increases the biogas potential and results in more biogas and more green energy. • Final drainage by means of a decanting centrifuge or dewatering screw presses. Decanters were installed at Egå and Marselisborg Wastewater Treatment Plants around the turn of the millennium, and our experience in this field can help make the right choice of separation/filtration equipment to ensure good and stable operation and sound economy.

14 Marselisborg Ressourceanlæg | Visitkort katalog 2 ARTOGIS A/S

ARTOGIS is an IT company, whose products and services are based on a free, open and flexible IT platform relying on global, open-source technologies that provide the scope for the development of innovative IT solutions that ensure future supply, the infrastructure, and environmental and climate control measures. www.artogis.dk

Contact: Henrik Rask, CEO, [email protected]

Contribution to addressing the innovation challenges

With ARTOGIS’ participation in the MUDP Lighthouse project ‘HEPWAT’ we create an open and flexible IT platform based on global open-source technologies (the latest generations). The IT platform integrates the technology fields of GIS, IoT, Big Data and BI/ Analytics and aims to streamline system integration and enhance the free movement of data.

AGS 3.x HEPWAT is released as open source for the development of network solutions, agile software solutions and collaborative economy, for the benefit of all waters and the climate (and the economy of the utilities). Open-source technologies offer a higher degree of migration/dispersion with no requirement that the utilities be based on a specific commercial IT platform. This is good for exports and, if used to advantage, this could support export of Danish environmental technology.

Finally, we believe efficient use of information technology is a prerequisite for the realization of the United Nation’s worldwide goal of sustainable development (here, SDG Nos. 6 and 13) – and here open-source technologies have the best prerequisites for global spread, especially in the developing countries.

How Aarhus Vand can contribute

Aarhus Vand is known for their great innovation will, their high professionalism, export orientation and good contacts abroad and is therefore a much-valued sparring partner. Aarhus Vand could also be a valuable catalyst for IT supported innovation in the water sector – also for the benefit of Danish exports, and thus the waters of the world and the climate.

Marselisborg ReWater | Business Card Catalouge 15 3 GREENSPEED®THE PROCESS

GreenSpeed® the process was developed in a VTU supported project with the participation of Teknologisk Institut, Aarhus Universitet, Bio-Aqua A/S and Helmo Consult, among others. All further development work and all commercial rights to GreenSpeed® the process lie with entrepreneur GreenSpeed IVS.

Contact: Kim Helmo, [email protected]

Contribution to addressing the innovation challenges

GreenSpeed® wastewater treatment is a new patent-pending process for biological treatment of wastewater, nutrient rich waste streams and CO₂ from energy production, etc.

In a preliminary process step, the organic material is absorbed/transformed by bacteria, while the nutrients (nitrogen, phosphate, potassium, etc.) are led on to a process step with photosynthetic organisms, e.g. micro algae. Here the nutrients are absorbed in an algae biomass. By simple separation, the algae biomass is split into different fractions, e.g. a liquid NPK-fraction and a solid carbon- rich fraction for biogas production or biorefining, from which high-value products can be extracted.

A conventional wastewater treatment plant can easily be converted to the GreenSpeed®process. The conversion consists of a resource caption plant where NPK is bound in an algae mass and with a considerable increase in the caption of carbon for biogas production.

Conventional wastewater treatment consists of the removal of nitrogen (ammonium/nitrate) through nitrification and de-nitrification. Both processes require a substantial amount of process volume and energy. However, they result in the release of large amounts of climate threatening greenhouse gasses - primarily in the form of CO2, nitrous oxide, etc.

During the GreenSpeed®process, the CO2 production of bacteria will be transferred and bound in an algae biomass and therefore not released into the atmosphere. Since traditional nitrification/de-nitrification is not in use, there is no production of nitrous oxide. The GreenSpeed®process is a closed process with marginal release of greenhouse gases, and the surroundings are not exposed to the odors normally associated with traditional wastewater treatment plants.

How Aarhus Vand can contribute The patent-pending GreenSpeed®the process has been subjected to laboratory and pilot-scale testing. Now partners are being sought for demonstration projects, product maturation of process equipment and possible separation/biorefining of end products. Aarhus Vand is a potential business partner for these development activities, not least because of their high level of ambition when it comes to the innovation strategy for Marselisborg ReWater.

16 Marselisborg Ressourceanlæg | Visitkort katalog 4 GRUNDFOS HOLDING A/S

Grundfos is one of the world’s largest producers of pumps, including centrifugal pumps for the industry, wastewater treatment, supply and dosage, among other things. To maintain a leading position in the market, Grundfos focuses on continued research and development and performs large-scale, global development tasks. www.grundfos.com

Contact: Ole Hejn Pjengaard, Director, WU Business Development, [email protected]

Contribution to addressing the innovation challenges

• Removal of hydrogen sulfide at the pumping station at Marselisborg ReWater and/or in the pipe system to the wastewater treatment plant. The formation of hydrogen sulfide in sewers is a complex process that depends on many factors. An ideal solution must therefore be based on the actual operating conditions. The basis of the Grundfos hydrogen sulfide solution consists of an advanced control algorithm in Grundfos Dedicated Controls. Based on data, the algorithm automatically calculates a dosage set-point for chemicals such as iron sulphate. The calculated set point is then transferred to a Grundfos SMART Digital dosing pump, which dispenses the chemicals with high accuracy even at varying flow quantities.

• Optimization of aeration tank design and energy consumption for the agitator and aeration. Regarding the design of the biological wastewater treatment, Grundfos has previously been involved in the design of aeration tanks to ensure optimal design and positioning of the agitator and aeration equipment. To ensure that the hydraulic flow in the tank will be as efficient as possible without compromising on sedimentation or process efficiency. Furthermore, our agitators/flow makers are currently the most energy-optimal on the market.

• Tertiary treatment of drains and sludge treatment through a) optimization of the disinfection of drains using dosing-pump solutions or UV treatment and b) optimization of sludge drainage by optimum polymer dosing and optimization of coagulation processes. Discharge of treated wastewater to a sensitive recipient or for surface irrigation requires tertiary treatment such as filtering and/or disinfection during water’s polishing phase. Grundfos can supply pumping systems for the various demands at this stage of wastewater treatment. Disinfection reduces the number of pathogenic bacteria and improves the quality of the wastewater. Conditioning/draining of sludge minimizes the volume of the sludge so that the necessary size and capacity are reduced in subsequent treatment processes and associated equipment. In addition, a reduction of the water content reduces the energy consumption involved in heating the sludge in the digester. Grundfos can supply PLC-controlled, fully automatic systems for handling the preparation and reliable dosage of organic coagulants or polyelectrolytes and a dosing station where chemicals are used as concentrates, ready solutions, or dry chemicals.

• Integration of Marselisborg ReWater in SMART CITY for wastewater (IoT). Grundfos works towards optimizing a complete sewage network in relation to energy consumption, maintenance and hours spent on troubleshooting and optimization of unauthorized in- coming water. Grundfos SMART CITY will tell you about the location and amount of wastewater so that you can optimize the flow into Marselisborg ReWater, and Aarhus Vand can use it for handling situations with heavy rain to minimize overflow in the sewers. Marselisborg ReWater | Business Card Catalouge 17 5 BBK BIO AIRCLEAN A/S

BBK bio airclean produces environmentally friendly, biological filter solutions for odor removal in biogas, wastewater and compost facilities. BBK bio airclean specializes in bio-filters for all types of works, and their products have been tested and used at more than 100 plants at home and abroad.

www.bbk.dk

Contact: Arne Poulsen, Director, [email protected]

Contribution to addressing the innovation challenges

BBK bio airclean was founded in 1992 with the aim of developing and producing an eco-friendly biological air cleaning solution to efficiently convert odoriferous substances to water and CO2. The solution was a further development of the well-known principle that involve biological filters to meet the following requirements:

• High cleaning effect • Long life • Homogeneous filter mass • Optimal biological growth • Tolerance to changes in pH and temperature • Option for pH adjustment • Control of the humidity of the filter material • Survival during downtime

BBK bio airclean has since developed and optimized the bio filters and specializes in the removal of unpleasant odors from wastewater treatment plants close to residential areas, for instance. BBK’s filter material consists of fully-composted organic material, expanded clay, moler earth, and selected naturally occurring micro-organisms. The major activity of odor-destroying organisms works immediately after start-up and typically gives a purification effect of more than 95%. At the same time, BBK’s filter material is reliable for years without emitting any pollution or causing waste problems.

How Aarhus Vand can contribute

By joining forces, we may be able to create a new exciting concept that can be copied and used by municipalities with a similar focus on odor elimination. In terms of development, the big challenge is that of minimizing the cleaning of the air without compromising the cleaning effect; this is where we can take advantage of letting Aarhus Vand’s other partners take part in the development.

18 Marselisborg Ressourceanlæg | Visitkort katalog 6 DHI DENMARK

DHI is an independent, international consultancy and research organization which specializes in the water environment and which has been approved as a technological service institution (GTS). DHI offers a wide range of advisory services, modeling tools, laboratory tests, physical model tests, field measurements and monitoring programs based on comprehensive Danish and international research knowledge. www.dhigroup.com

Contact: Torben With Ottosen, Business Development Manager, [email protected]

Contribution to addressing the innovation challenges

Optimization of wastewater treatment plants and testing of new methods for wastewater treatment are two of DHI’s focus areas. Having worked together with Aarhus Vand on energy and CO2 optimization for a number of years, we have a natural desire to assist Aarhus Vand in the process consortium. The inclusion of new processes considered most advantageous for the new Marselisborg ReWater will typically also affect other processes at the plant, e.g. the removal of nutrients in wastewater. That is why it is important to shed light on the overall mass balance to assess the effect of including these new treatment process.

What with their holistic approach to the city’s water – coupled with professionalism and modular insight – we consider DHI to be an excellent match for Aarhus Vand’s forthcoming work with Marselisborg ReWater, and Aarhus Vand’s plans to function as water operator. In other words, DHI will be a strong partner when it comes to establishing an independent professional basis for the choice of process solutions for the future plant.

DHI has no commercial interests in the subsequent design and execution and will therefore be able to act as an independent adviser to Aarhus Vand throughout the project cycle. As an independent participant in a broad process consortium during the course of the project, DHI will be able to assist in anchoring and qualifying knowledge and technologies from a broad-based team of national and international experts.

How Aarhus Vand can contribute

Globally, the water resource is under pressure and reuse of treated wastewater should therefore be thought into the Marselisborg ReWater concept. We are already working with a wide range of industries to reduce their aquatic footprint through optimized exploitation of the water resource and through our ability to carry out specialized analyses for water characterization. This knowledge will be of great value to Aarhus Vand and the entire industry.

Aarhus Vand is already today considered a strong partner by DHI in relation to our ambition of continuously developing innovative solutions for the water sector and marketing them abroad. As a global company based in Denmark, DHI considers cooperation with Aarhus Water to be crucial.

Marselisborg ReWater | Business Card Catalouge 19 7 OXYMEM

OxyMem provide products and services which continue to challenge the inefficiencies of the past 100 years. In doing so we enable our customers to build and operate energy efficient biological wastewater treatment plants and allowing them to get closer to energy neutral wastewater treatment goals.

www.oxymem.com

Contact: John McConomy, Commercial Director, [email protected]

Contribution to addressing the innovation challenges

OxyMem provide the most advanced and lowest operational cost biological wastewater treatment solution, specializing in the design and manufacture of MABR (Membrane Aerated Biofilm Reactor) modules. The technology is extremely easy to install and operate. Each module, when submerged in wastewater, will establish a robust attached-growth biomass that treats biological pollutants, while consuming approximately 75% less power than conventional treatment systems. Modular in form, the MABR units are highly scalable and therefore ideal for plants where process loads may increase over time. OxyMem MABR modules can be deployed within flexible all-encompassing package plants or can be dropped, in their simplest form, into an existing facility one unit at a time, to reduce COD and Ammonia. A modular wastewater treatment approach such as OxyMem’s MABR would provide Aarhus with a flexible, cost effective means of improving effluent discharge water quality for years to come; maintaining a clean harbour as the region’s population grows over the next 40+ years. The scalable modular approach negates the need for substantial investment in large fixed civil assets and potentially oversized equipment which has been designed and procured to cope with larger future loads.

OxyMem’s technology has been demonstrated at length on a diverse range of multiple wastewaters and for a number of clients. For one demonstration, units were operated for 12 months as a side-stream system on Severn Trent Water’s largest WwTW, Minworth, UK (~ 1.7M Population Equivalent). STW collected data from six MABR modules and the results confirmed that within the smallest footprint and while consuming little power (8+kgO2/kWhr), OxyMem’s technology removed <90% COD and Ammonia. Sludge collection hoppers below each module collected all waste sludge produced over three months and volumes showed that the OxyMem MABR also produces approx 50% less sludge than conventional ASPs (~0.15 kgTSS/kgCOD removed). This cutting-edge technology has proven it can assist plant owners achieve energy and CO2 neutrality as part of a sustainable water solution.

How can Aarhus Vand contribute MABR technology is a relatively new means of biologically treating wastewater compared to traditional methods. Engineers, owners and operators across the world would benefit from seeing this technology being used by Aarhus Vand, as it will help provide them with the confidence to integrate an MABR system (as new build or retrofit) on their own plants; improving effluent quality or increasing biological treatment capacity. An OxyMem installation on this showcase, advanced technology Aarhus facility would gain global recognition and thus increase awareness for MABR treatment in general.

AAMS is Denmark’s largest school of marine and technical engineering, and since 1896 it has offered an up-to-date and attractive program in marine and technical engineering. www.aams.dk

Contact: Frits Giversen, Associate Professor, Mechanical Engineer, [email protected]

Contribution to addressing the innovation challenges

The program in marine and technical engineering qualifies our students to function as technical managers who can think in – and work with – complex systems with a focus on operations, maintenance and optimization of technical plants and installations for the purpose of optimizing resource utilization. The program is problem and project oriented with an emphasis on innovation and practice-based development in an international perspective.

AAMS has three tracks in their strategy of R&D, which are to be developed in close collaboration with relevant partners:

• Sustainability • Learning organizations • Big data

In an innovation and development phase, AAMS can contribute to maturing and optimizing processes in relation to the practical construction and operation in areas such as mechanical engineering, electricity, control, automation, maintenance, environment, and leadership. Students may take part in research and development projects and bachelor projects, at Aarhus Vand and at relevant companies with an interest in the area. Here AAMS, with their many years of experience from both the private and public sectors, can potentially contribute with resources that make sense to both Aarhus Vand and AAMS.

How Aarhus Vand can contribute Learning through practice-close relations and tasks is important and creates great value for everyone involved. A collaboration with Aarhus Vand will work to our mutual advantage. Aarhus Vand’s goal is to build the world’s most resource-efficient wastewater treatment plant, and it is AAMS’ goal to train today’s technical leaders to meet the future demand for operation handling, optimization and maintenance. old.

Marselisborg ReWater | Business Card Catalouge 21 9 UNISENSE A/S

Unisense develops, produces and sells advanced sensory systems for research and industrial applications and is a market leader in electrochemical micro-sensors for the measurement of dissolved gasses (e.g. O2, H2, H2s, N2O)

www.unisense.com

Contact: Ebbe Kruse Vestergaard, Technical Business Developer, [email protected]

Contribution to addressing the innovation challenges

Unisense has for years been working with the measurement of nitrous oxide emissions (N2O) from wastewater treatment plants. In collaboration with research groups around the world, a solid foundation of knowledge has been gained of which parameters affect the production and emission of nitrous oxide, an extremely effective climate gas. There is widespread agreement in research environments that nitrous oxide is one of the most important factors in the carbon footprint of the wastewater sector; however, there is still only few examples of wastewater treatment plants which have implemented full-scale monitoring for the purpose of minimizing the emission of nitrous oxide. In relation to Marselisborg ReWater, we can help ensure that the new plant becomes trendsetting and future-proof when it comes to minimizing the negative impact of wastewater treatment on the environment.

Another important contribution to Marselisborg ReWater worth highlighting is the new hydrogen sulfide sensor (H2S) for the measurement of dissolved H2S. The sensor provides unique opportunities for control and monitoring of odors and corrosion, and at present, a system is being tested in a VUDP supported project. Unisense is happy to cooperate on future projects such as mapping/ tracking sources of odors and corrosion in connection with the plant or the pumping stations in the surrounding area.

How Aarhus Vand can contribute

We want to integrate the nitrous oxide sensor and the hydrogen sulfide sensor in the full-scale management of a wastewater treatment plant such as Marselisborg ReWater. With respect to the nitrous oxide sensor, full- scale management will provide a good case that exemplifies that visionary water utilities want to be climate-neutral and do not focus exclusively on energy neutrality. In the case of the hydrogen sulfide sensor, the performance of its sensor is being tested in the sewer network, but the challenges with hydrogen sulfide- related odors will be different at the wastewater treatment plant. We imagine that the H2S measurements may be relevant for inlets, in digesters, and for the treatment of “side stream water” from the digesters.

Sunstone Water Group’s design philosophy is decentralised water treatment and purification, at the point source of pollution, by using state-of-the-art filtration techniques. www.sunstonewater.com

Contact: Daniella W. Andreassen, Marketing Manager, [email protected] Sune Neve, CCO, [email protected]

Contribution to addressing the innovation challenges

Sunstone Water Group engages in water purification projects for global applications whether they are drinking water projects from natural water sources or pre-treated wastewater. Our technology is compact, modular and it includes sturdy membranes and advanced filtration processes. The process is fully monitored and the solution is scalable.

This technology can also be utilised to polish treated municipal wastewater to achieve a two-fold effect; firstly, to protect the aquatic environment by removing micro-pollutants from the wastewater. Furthermore, reduction of fresh water intake will be possible as the treated water can be recycled in near-by industries, for watering of parks and so forth.

Sunstone Water Group has engaged in the past in a so-called “Toilet-to-tap” project in Texas USA, to demonstrate its treatment capabilities. In a European context, we witness recent legislation in Switzerland and some areas in Germany, which specifically targets the removal of micro-pollutants from municipal wastewater effluent, including xenobiotics. It seems likely that the European trend will reach Denmark as we already witness the increased focus and public debate on the importance of incorporating best available technologies and rethinking current water standards.

How can Aarhus Vand contribute

While Danish utilities may choose to upgrade treatment solutions first when legislation takes effect, the Marselisborg ReWater project is already committing to it, which gives technology suppliers a unique opportunity to become a first mover in the field. Similarly, the ability to cooperate with strong entities within the water sector will create beneficial synergies for the applied technologies that will improve Denmark’s wastewater quality.

Contribution to addressing the innovation challenges

Krüger can contribute to developing and using state-of-the-art technology in coherent solutions consistent with the desire to build the world’s most resource-efficient wastewater treatment plant.

The framework for the Marselisborg ReWater is that the water be cleared of: N, P, COD, bacteria and anthropogenic substances. It will be possible to supply treated water of different qualities in accordance with the dynamic needs of consumers. There will be a focus on surveillance, warning and control (design) of wastewater flows so that discharges are reduced and cleaned in relation to the needs of the harbor environment. The designs are modular allowing for flexible capacity in relation to a growing city. Flexibility will be embedded in the constructions as well as the mechanical equipment. The city’s confidence is earned with real-time documentation of performance and the city’s opportunity to share the experience of the water cycle again and again. The modular build-up consists of compact processes with minimal impact on the immediate environment and a design that ensures flexibility in the combination of the plant units; this way cleaning can be organized in accordance with the wastewater design and requirements of the recipient and owner. The design allows for a flexible test line, which can be used for continuous testing of new concepts and new technologies in a controlled environment, and new sensors such as online DNA can be tested on an ongoing basis.

Resource utilization is the heart of the matter in all the choices we make. An example: Cleaning processes with a high degree of energy conversion from COD to energy, methanization, sludge incineration, N and P recovery, recycling of metals and ash residue in new custom-designed products, heat utilization, Smart Grid and Smart Energy. Work with resource exploitation based on the value that the products represent now and in the future. The establishment of Marselisborg ReWater using VR/3D in the design and start-up phase to minimize errors and ensure effective delivery and operation. Krüger wants a strong cooperation with a contractor interested in the same type of commitment.

How Aarhus Vand can contribute At Krüger, development takes the need for digitization as its starting point, using big data analysis and machine learning in practice.

Contribution to addressing the innovation challenges

Rambøll offers a holistic input to the innovation challenges, a Marselisborg ReWater built with the very treatment part below ground, leaving the terrain for recreational uses. Rambøll has concrete project experience from several underground construction work, including wastewater treatment plants.

Part of the above-ground plant will be established as a lighthouse-like tree of life, YGGDRASIL, “showing the water flow” literally & symbolically. The building is thought of as an iconic symbol of the city, whose roots go back to the Viking Age and tell the tale of a symbiotic society, which is the result of connecting land to air, land to water, people to the city, and company to company.

A holistic approach to the task focuses on:

• Exploring and clarifying the possibilities for choosing a solution sufficiently compact to make it financially feasible to establish the future resource facility, Marselisborg ReWater, with a treatment plant underground and an above-ground “urban space” for the enjoyment of city residents. • Optimizing and developing the symbiosis, process technically and as a business model, through a strategic approach to land use, urban development and urban renewal, incl. strategic measures to attract specific business types. The symbiosis approach is essential to strengthening the understanding of what a resource facility is, and why it makes sense to place it near the city center. The establishment of Marselisborg ReWater will give the citizens some new attractive recreational sites and not “just a new wastewater treatment plant by the harbor”. • Ensuring optimized interaction between robotics, artificial intelligence and human skills to reach “new heights” in the automation of dirty, heavy and unhygienic work flows and processes. • Redesigning the water cycle, ensuring a minimal discharge of water into the bay, optimal “city-symbiosis”, resource recycling and contributing to the circular economy through the recycling of resources such as phosphorus, electricity, district heating and cooling, reuse of water in different qualities, etc. • Establishing close, innovative and trustful cooperation with everyone who wish to - and who can do - this!

Contribution to addressing the innovation challenges

During our 135 years of experience – and in cooperation with our clients – Royal HaskoningDHV have developed numerous innovative products in our home markets and delivered solutions for the captioned challenges. We have over a hundred (international) references and continue to develop and improve.

What we would specifically like to bring forward: Nereda is the wastewater treatment technology that purifies water using the unique features of aerobic granular biomass. Nereda is sustainable and cost-effective: it requires a quarter of the area of conventional activated sludge installations and the process can reduce up to 50% on energy-costs. The award-winning technology was invented by the Delft University of Technology in the Netherlands and developed in a unique public-private partnership between the University, the Dutch Foundation for Applied Water Research (STOWA), the Dutch Water Authorities and Royal HaskoningDHV.

Biomass in Nereda develops as fast settling aerobic granular sludge. These granules have excellent settling properties and therefore Nereda does not require a separate time-consuming decant phase like conventional SBR’s. Further, all the biological treatment processes take place simultaneously in the granules, requiring only one tank. Due to the distinctive characteristics of aerobic granular biomass, Nereda technology uses an optimised SBR cycle: 1. Simultaneous influent feed and effluent discharge. 2. Simultaneous biological removal of organic, nitrogen and phosphorous components. 3. Fast settling phase, in this phase the biomass is separated from the effluent and Nereda is ready for a new cycle.

Since the effluent is pushed out of the tank, discharge of the effluent does not require moving decanters. Depending on the wastewater flow and characteristics, a Nereda plant comprises multiple modular reactors (often 3) or a combination of a feed buffer tank plus one or two reactors.

Contact: Tore Krautwald, Head of Department, [email protected]

Contribution to addressing the innovation challenges

EnviDan would like to focus on a holistic approach to Marselisborg ReWater, where, early in the process, we look at the prioritization of resources and products providing most value in a future perspective. At this stage, an assessment will be made of the systems and methods that translate into the best symbioses and synergies in relation to the total resource facility, resource recipients, Aarhus city, the bay, and the inhabitants. This work must be performed to ensure a future-proof and flexible Marselisborg ReWater, where innovation and further development are incorporated from the outset. This process should help to provide a basis for work on specific innovation projects.

From EnviDan’s long list of innovation ideas, we have selected three concrete innovation projects that we want to go on with:

• Optimization of carbon harvesting using high-rate biosorption and MBR the purpose of which is to move more dissolved/colloidal carbon to the energy flow.

• Nitrogen removal at low C/N conditions using Membrane Aerated Biofilm Reactors (MABR)/Hybrid Membrane Biofilm Process (HMBP) technology to minimize the requirement for oxygen, reduce space requirements and increase flexibility.

• Production of protein products based on methane to evaluate the potential for extracting intermediates for the pharmaceutical and food industries.

How Aarhus Vand can contribute

EnviDan would like Aarhus Vand to become a close sparring and innovation partner in the areas to be further developed and tested in an innovation process, be it theoretically or through small/large-scale practical development trials - preferably on Aarhus Vand’s existing installations from supply network to treatment plant.

Contribution to addressing the innovation challenges

Technological Institute wants to contribute with knowledge about the microplastics and technology for harvesting carbon and microplastics to address innovation challenges #2, 3, 4 and 6. We propose to conduct experiments using band filter technology to harvest carbon and microplastics in the primary part of the wastewater treatment plant.

Preliminary trials conducted in an ongoing MUDP (environmental technology development program) project suggest a carbon harvest of 70-80% of COD across the band filter (challenge #3, 4 and 6) and capture of more than 99% of microplastics particles with a size of ca. 100 micrometers (challenge #2). This has been tested at a pilot-scale plant with band filter technology from AL-2 Teknik. We propose that the project be implemented as a partnership between AL-2 Teknik, Teknologisk Institut and Aarhus Vand.

How Aarhus Vand can contribute

Aarhus Vand’s role will be to contribute with testing facilities, to participate in the operation of the band filter plant, and to assist in applying for support for market maturation of the product.

# 2: How do we create a cleaner harbor and Aarhus Bay, while we at the same time clean the water from a growing city? Examination of the possibilities for compensatory removal of nitrogen and phosphorus further up the recipient system. The potential of this option can be investigated through the establishment of mass balances to reveal how many ha of nitrogen wetland or constructed wetlands must be established to compensate for the extra emission of nutrients comparable to a population increase of 40,000 PE and a 10- year planning horizon. Screening of the potential and investigation into any available areas. The costs of this solution are calculated and compared with the costs of central cleaning.

# 4: How do we achieve energy and CO2 neutrality in the water cycle throughout the Marselisborg catchment? Improved utilization of biogas with increased CO2 reduction and possibly increased biogas production. Traditionally, biogas production at the wastewater treatment plants is utilized to produce electricity primarily, and, secondly, heat energy. In recent years, this has been strongly encouraged through public subsidies for electricity production based on biogas. These subsidies are expected to be reduced or lapse in 2020, and the financial gain of using biogas for the production of electricity will then be dubious. When biogas is upgraded to natural gas quality and used as fuel for automobiles, the CO2 reduction is today more than 3 times higher compared to when it is used for the production of electricity. With the increasing amount of green electricity, the replacement of CO2 - when biogas is used for the production of electricity - will be negligible.

How Aarhus Vand can contribute

Aarhus Vand and NIRAS can support each other in the exploration of opportunities and potentials – also in interaction with Aarhus municipality’s energy system - as the basis for choosing a strategy for the further course. For the energy part, the strategy can be based on known technologies or trials, including trials with methanization, whereby biogas production can be increased by 50%. Overall, a better understanding of the biogas process could optimize the utilization of raw materials and production equipment for the benefit of the climate through the replacement of fossil fuel and improve the economy for Aarhus Vand in the long term. Biogas can be developed as a dynamo in circular economy.

Rethinking your plant, by challenging the benefits of gases for the society, while optimizing operating costs, industrial gases can provide you with a truly effective solution for a more sustainable plant.

The Nexelia Solution: Nexelia for Biological Treatment is an all-in-one gas solution, which consists of introducing pure oxygen into biological basins for the respiration of microorganisms (activated sludge) which consume biodegradable pollution. In combination with ozonation, it also stimulates the whole biological process in a very efficient manner.

As injection up to 6.5 kg O2/kWh is possible, a lot of energy can be saved in comparison with conventional aeration membranes or injectors. As there is almost no stripping with Pure Oxygen, the T° stays stable, as well the nitri/denitri process. This makes the use of Pure Oxygen very user friendly. Other effects of the no-stripping are no odour, foam or aerosol (legionella) issues and much less emissions of greenhouse gases to the atmosphere. A safe environment to operate. And you don’t need to build an expensive cover on your WWTP, your footprint will be smaller. The more stringent specs for hard COD and micropollutants in the future can be tackled with O3, produced on site with O2. The off-gas will be recovered as well.

An integrated ‘gas-based’ concept, inclusive nutrient recovery, H2 production, biogas upgrading, potable water production, urban farming and clean energy mobility can help in building an innovative and resource friendly UWWTP.

Contact person: Heidi Christiansen Barlebo, Head of Department, [email protected]

Contribution to addressing the innovation challenges #2: How do we create a cleaner harbor, while we at the same time clean the water from a growing city? • Subsurface injection of treated wastewater in the coastal zone could add additional purification to the treated wastewater before undersea discharging into the Aarhus Bay, and hereby improving the water quality of the harbour and the bay. Through different research and development project (e.g. www.subsol.org and www.seamount.eu) GEUS has experience with hydraulic barrieres, subsurface groundwater discharge, managed aquifer recharge techniques and water quality assessements of cosatal groundwater aquifers which can help in finding new innovative solutions to subsurface injection. • Local infiltration, retention and storage of rainwater from stormwater events can reduce excess discharge of water of poor quality to the habour and the bay. The use of e.g. LID (Low Impact Development) and soakaway techniques can be improved by in- depth understanding and modeling of the urban geology. Based on GEUS expertise we propose modeling of the urban hydrology, building 3D-models of the subsurface geology in the coastal zone and Aarhus Bay, and modeling effects of LID/soakaway technologies.

#4: How do we achieve energy and CO2 neutrality in the water cycle throughout Marselisborg’s catchment? • Geothermal energy technologies can be used for both heating and cooling of facilities and processes and for storage of surplus energy. GEUS is involved in several collaborative projects investigating geological, environmental and technical conditions relevant to heat storage, storage capacity and temperature influences by modeling different geological conditions and technical solutions (e.g. www.geoenergi.org and http://dybgeotermi.geus.dk/geotherm/). GEUS experience within this can help in building innovative and energy friendly solutions.

#6: Waste water as a potential mineral resource? • Wastewater contains important raw materials like phosphor and a wide range of metals. How much does the waste water in Aarhus contain, and is it technically and economicly feasible to recycle such elements? GEUS is actively participating in international projects and networks on urban exploration and urban mining, and GEUS is leading a Centre for Minerals and Materials (MiMa) (http://mima.geus.dk/).

CERE maintains a collection of software which can be used for process design, simulation and optimization. CERE offers a significant lab for chemical analysis and large scale pilot demonstration.

As part of a future collaboration with Aarhus vand, CERE expects four topics to be in-line with the “Innovation Challenge”, and there could easily be more: 1. Biogas upgrading with BioCO2 production to reduce CO2 emissions 2. Phosphorous recovery using a new Struvite-K technology. A technology which allow for a higher percent recovery of phosphorous, resource re-use, with better access to plant fertilization 3. Removal of impurities like poly aromatic hydrocarbons, pharmaceuticals, and multi resistant bacteria. A technology which allow for reduced use of chemicals, but also for other applications like pH control, aeration, and sterilization. 4. New resources in terms of public funding through research projects

These topics cover innovation challenge 4, 6, 7, and 12 Aarhus vand should see CERE as an educational partners which can mature new employees.

How can Aarhus Vand contribute DTU CERE is a research organization funded by public, EU, and industrial funding. If Arhus vand is interested in participating in public research project, it requires that Aarhus vand participate actively in the project development in terms of supplying the project with access to facilities, samples, knowhow, and engineers to support the knowledge creation. Many projects are only funded if CERE can show co-funding and participation from partners, Aarhus vand can be a vital contributor in this sense.

Currently, secondary calculations and controls in all equipment. Digital connectedness water is used in the low value steps (for example treated water holds significant potentials, not only when it comes to mutual for cooling, irrigation, flushing/cleaning/washing (e.g. washing optimization of the individual steps in the purification process, of boats/flushing of sewers/irrigation of green areas/urban but also in relation to the plant’s localization in an overall “smart grading)). The challenge ahead of us is to develop solutions that grid”. If this ambition is to be fulfilled, it requires development allow upcycling of water, for industrial production, for instance. and integration of sensors, data processing, controls, etc. Some Aarhus Vand has an interest in entering into partnerships with of these areas are new to the water industry - integration of consumers of highly refined water and parties who can provide robots, drones, gene sequencing - and Aarhus Vand therefore equipment to produce and document refined water wishes to cooperate with knowledge institutions and companies within this field. 60 Marselisborg Ressourceanlæg | Visitkort katalog Areas with others problem owners • Cleaning upstream: There are a number of different approaches The following are examples of issues where Aarhus Water expects for how to improve the water quality by solving the problems to play a minor role: upstream.

Marselisborg ReWater | Business Card Catalouge 61 • Next-generation biological purification: A number of new biological purification processes are facing imminent breakthrough: membrane bio-reactors (MBR), Moving Bed BioReactors (MBBR), granular sludge process, etc. A systematization of the development and, not least, testing of the solutions with a view to improved treatment for substances alien to the environment etc., will within a 3-year period – and thus in time for the choice of technology for Marselisborg ReWater – make it possible to assess their efficiency, reliability and economy. In other words, the project can be carried out now at existing plants as maturation towards Marselisborg ReWater, and Aarhus Vand will therefore not be a driving force.

• Go for the gold – removal and extraction of precious and heavy metals: There are currently no technologies for effective and profitable capture, and thus neither disposal nor recycling, of precious and heavy metals when present in low concentrations in water or sludge. What is required is a national basic research project that considers what basic principles – probably at nano scale — exist within physics, chemistry and biology that can transform this into solution approaches. Aarhus Vand assesses that this is a basic research project with general and long-term relevance and therefore not a project naturally associated with an individual plant.
