  • Inclusive Business Models for Wastewater Treatment
    INCLUSIVE INNOVATIONS Inclusive Business Models for Wastewater Treatment Enterprises have developed integrated, affordable wastewater treatment solutions for industries and households to encourage reuse or safe disposal HIGHLIGHTS • Wastewater treatment enterprises treat water before disposal or recycle the water so that it can be reused. • Enterprises provide household wastewater treatment systems that are modular, have low operating costs in terms of electricity and maintenance, have silent operation and less odor and offer quick returns on investment. • Enterprises focusing on industrial wastewater treatment solutions offer efficiency and cost effectiveness. They are quickly commissioned, fully automatic, have remote monitoring, require minimal hazardous chemicals, and treat water for reuse. Summary Wastewater sources include domestic wastewater—pertaining to liquid outflow from toilets, bathrooms, basins, laundry, kitchen sinks and floor washing, and industrial wastewater—effluent water that is discharged during manufacturing processes in factories or by-products from chemical reactions. There are significant operational and financial challenges associated with wastewater treatment in marginalized residential communities, where domestic wastewater does not get treated at source, but instead is discharged to local municipal facilities or directly into water bodies. Similarly, industrial wastewater is heavily contaminated and leads to pollution and diseases, if disposed without treatment. It may also contain metals that have high market value and could potentially be recovered. Social enterprises have introduced unique technologies and integrated solutions to treat such wastewater either for safe disposal or for reuse. These solutions aim to be efficient, affordable and convenient. There are two major types of wastewater treatment plants—household (residential) systems and industrial systems. This series on Inclusive Innovations explores business models that improve the lives of those living in extreme poverty.

  • Use of a Water Treatment Sludge in a Sewage Sludge Dewatering Process
    E3S Web of Conferences 30, 02006 (2018) https://doi.org/10.1051/e3sconf/20183002006 Water, Wastewater and Energy in Smart Cities Use of a water treatment sludge in a sewage sludge dewatering process Justyna Górka1,*, Małgorzata Cimochowicz-Rybicka1 , and Małgorzata Kryłów1 1 University of Technology, Department of Environmental Engineering, 24 Warszawska, Cracow 31- 155, Poland Abstract. The objective of the research study was to determine whether a sewage sludge conditioning had any impact on sludge dewaterability. As a conditioning agent a water treatment sludge was used, which was mixed with a sewage sludge before a digestion process. The capillary suction time (CST) and the specific filtration resistance (SRF) were the measures used to determine the effects of a water sludge addition on a dewatering process. Based on the CST curves the water sludge dose of 0.3 g total volatile solids (TVS) per 1.0 g TVS of a sewage sludge was selected. Once the water treatment sludge dose was accepted, disintegration of the water treatment sludge was performed and its dewaterability was determined. The studies have shown that sludge dewaterability was much better after its conditioning with a water sludge as well as after disintegration and conditioning, if comparing to sludge with no conditioning. Nevertheless, these findings are of preliminary nature and future studies will be needed to investigate this topic. 1 Introduction Dewatering of sludge is a very important stage of the sludge processing. It reduces both sludge mass and volume, which consequently reduces costs of a further sludge processing, facilitates its transport and allows for its thermal processing.

  • Anaerobic Digestion of Wastewater Sludge (Nazaroff & Alvarez-Cohen, Section 6.E.3)
    Anaerobic Digestion of Wastewater Sludge (Nazaroff & Alvarez-Cohen, Section 6.E.3) nice, clean water going to disinfection and then to outdoor body of receiving water (stream, lake or sea) sludge in need of further treatment The goal is to reduce the amount of sludge that needs to be disposed. The most widely employed method for sludge treatment is anaerobic digestion. In this process, a large fraction of the organic matter (cells) is broken down into carbon dioxide (CO2) and methane (CH4), and this is accomplished in the absence of oxygen. About half of the amount is then converted into gases, while the remainder is dried and becomes a residual soil-like material. What the equipment looks like The tank is capped - to prevent oxygen from coming in, - to prevent odors from escaping, and - to capture the methane produced. This methane, a fuel, can be used to meet some of the energy requirements of the wastewater treatment facility (co-generation). What the sludge looks like after anaerobic digestion and subsequent drying. It is rich in nitrates and performs well as a fertilizer. (Photos from http://www.madep-sa.com/english/wwtp.html) 1 (Originally from Metcalf & Eddy, 1991) from & Metcalf Eddy, (Originally 6.E.7) Figure Alvarez-Cohen, & (Nazaroff How the system works The treatment of wastewater sludge, from both primary and secondary treatment steps, consists of two main phases. ● In the 1st step, all incoming flows of sludge are combined, and the mixture is heated to a mild temperature (about body temperature) to accelerate biological conversion. The residence time here ranges from 10 to 20 days.

  • Wastewater and Wastewatertreatment Explained
    Wastewater and WastewaterTreatment Explained Wastewater Wastewater is any water that has been adversely affected in quality by anthropogenic influence. It comprises liquid waste discharged by domestic residences, commercial properties, industry, and/or agriculture and can encompass a wide range of potential contaminants and concentrations. In the most common usage, it refers to the municipal wastewater that contains a broad spectrum of contaminants resulting from the mixing of wastewaters from different sources. Wastewater Treatment Sewage treatment, or domestic wastewater treatment, is the process of removing contaminants from wastewater, both runoff (effluents) and domestic. It includes physical, chemical and biological processes to remove physical, chemical and biological contaminants. Its objective is to produce a waste stream (or treated effluent) and a solid waste or sludge suitable for discharge or reuse back into the environment. This material is often inadvertently contaminated with many toxic organic and inorganic compounds. Sewage is created by residences, institutions, hospitals and commercial and industrial establishments. It can be treated close to where it is created (in septic tanks, biofilters or aerobic treatment systems), or collected and transported via a network of pipes and pump stations to a municipal treatment plant (see sewerage and pipes and infrastructure). Sewage collection and treatment is typically subject to local, state and federal regulations and standards. Industrial sources of wastewater often require specialized treatment processes (see Industrial wastewater treatment). The sewage treatment involves three stages, called primary, secondary and tertiary treatment. First, the solids are separated from the wastewater stream. Then dissolved biological matter is progressively converted into a solid mass by using indigenous, water- borne microorganisms.

  • Circular Economy in Wastewater Treatment Plant– Challenges and Barriers †
    Proceedings Circular Economy in Wastewater Treatment Plant– Challenges and Barriers † Ewa Neczaj * and Anna Grosser Faculty of Infrastructure and Environment, Czestochowa University of Technology, 42-201 Czestochowa, Poland; [email protected] * Correspondence: [email protected]; Tel.: +48-343-250-917 † Presented at the 3rd EWaS International Conference on “Insights on the Water-Energy-Food Nexus”, Lefkada Island, Greece, 27–30 June 2018. Published: 31 July 2018 Abstract: The urban wastewater treatment plants can be an important part of circular sustainability due to integration of energy production and resource recovery during clean water production. Currently the main drivers for developing wastewater industry are global nutrient needs and water and energy recovery from wastewater. The article presents current trends in wastewater treatment plants development based on Circular Economy assumptions, challenges and barriers which prevent the implementation of the CE and Smart Cities concept with WWTPs as an important player. WWTPs in the near future are to become “ecologically sustainable” technological systems and a very important nexus in SMART cities. Keywords: circular economy; wastewater treatment plant; resource recovery 1. Introduction The circular economy (CE) is the concept in which products, materials (and raw materials) should remain in the economy for as long as possible, and waste should be treated as secondary raw materials that can be recycled to process and re-use [1]. This distinguishes it from a linear economy based on the, ‘take-make-use-dispose’ system, in which waste is usually the last stage of the product life cycle. CE is a concept promotes sustainable management of materials and energy by minimalizing the amount of waste generation and their reuse as a secondary material.

  • Human Waste Management Topic Summary: the Human Population Produces a Significant Amount of Human Waste Every Year
    Human Waste Management Topic Summary: The human population produces a significant amount of human waste every year. Solid waste (feces) liquid waste (urine) and medical waste (blood, used health care supplies) are all produced in nations throughout the world on a daily basis. Disposing of the waste is often done unsafely, with some solid waste disposed of in drinking water, and medical waste left in landfills. Each year, waterborne illnesses, caused in part by improper disposal of solid waste, is the single greatest cause of death in the world. In most years, more people are dying of infections and diseases caused by unsafe water than armed conflict. Despite this fact, discussion of sanitation practices as a focus of public conversations is rare in most places in the world. Either the topic is taboo and uncomfortable (discussing it requires talking about feces), or people are ignorant of the need for sanitation practices to improve public health. While relatively safe human waste management guidelines have been developed by the international community, many nations have not made steps to improve public sanitation. In large part, this is due to lack of infrastructure and resources. The guidelines can’t be implemented successfully with a lack of equipment, lack of awareness, and lack of a mindful effort to safely dispose of waste. Further, medical waste, like syringes and used bandages, sometimes show up in general landfills. Often in least developed countries, children are tasked with picking through landfills for food or metals (which can be sold). One wrong step or move, and these impoverished children can be stuck with needles and contract fatal diseases.
