FILTRATION water for industrial/process applications or comfort cooling, requires a filtration system for suspended solids and a chemical or non-chemical based scale preventing/removal system. A cooling tower water treatment system is necessary in ensuring an efficient process and long equipment service life for your connecting components (heat exchangers, tubes, evaporative condensers, cooling tower basin, piping system and more) and also downstream equipment.

Water in cooling towers attracts and absorbs large volumes of airborne contaminants on a continuous basis - acting as an air scrubber filtering the surrounding air. With time, these fine particles can build up and settle within the system, adversely affecting cooling performance while lowering the life of sub-components.

Predominantly, the contaminants in the system are sand, silt, scale and rust. These contribute to the excessive creation of deposits (scale, corrosion, bio-fouling and biological activity), negatively impacting heat transfer efficiency. Solids accumulation in Cooling Towers and Condensers cause increased bacteria growth (legionella bacteria and other health risks).

Basis of Selecting the Right Technology • The quality of the make-up water being added to the system • The type of contaminants getting into the system, being regenerated within the system and already in the system • Filtration performance & particle removal rate for maximum process efficiency • The cycles of concentration at which the system is operating • The current chemical treatment program • The location of the cooling tower • The maintenance and operating requirements • Budget and footprint constraints.

Available Filtration Technologies Centrifugal Separators Centrifugal separators (or hydro-cyclones) are primarily selected due to the technology being the least expensive in terms of equipment costs. The separator utilizes centrifugal forces, spinning the water to separate the heavier particulate from the water. These separators are effective in removing suspended particles from the stream of water when the specific gravity (density) of the particles is heavier than the fluid it is in. The

Flush more significant the difference in density between water and the particle, greater the Valve efficiency of removal process.

Traditional Sand Filters Traditional sand (or media) filters direct the flow of cooling water onto the surface of the media bed. As the cooling water passes through the media, particles are captured within the layers of the media bed. The water than moves downward, passing into a drain at the bottom of the filter tank and discharging. Such filters have the capacity to remove organic particulate ≥10 microns. The system’s performance in removing fine particles highly depends in the type of media(s) being used within the filter bed.

Automatic Screen Filters The screen-filtering element acts as a barrier, removing all particulate (both organic and inorganic) down to 10 microns. Automatic self-cleaning screen filters are becoming the filter technology of choice for cooling tower filtration applications requiring removal of particles 10 microns and larger. During the self-cleaning process, this technology yields the least flushing discharge. Screen filters also provide uninterrupted filtration during the cleaning process, thereby requiring only a single filter for continuous 24/7 filtration.

Page - 10 // Cartridges & Bag Filters These systems can achieve removal of both organic and inorganic particles down to 1 micron without requiring a backwash cycle. They are the most flexible side stream solutions, adjusting the level of micron filtration as needed. However, these consumables can become costly with time. The cartridges and bags require monitoring and manual replacement.

High Efficiency Media Filters High efficiency media filters are similar to traditional sand filters, however, thesize, shape and weight of the micro-sand used in these systems allow for improved filtration efficiencies. The injectors generate cross-flow patterns that sweep the surface ofthe media. This sweeping motion causes a portion of the water to flow parallel to the top layer of the media, allowing for high efficiency sub-micron filtration performance while preventing media fouling at the surface and water channeling through the media.

Contaminants trapped upon and within the micro-sand media (depth filtration) are removed using an automatic backwash cycle. The system’s backwash cycle requires less flow and a shorter duration than traditional sand or multi-media filters. The result is a technology that removes particles down to sub-micron levels at 4 to 5 times the hydraulic flow rate of traditional media filters, while requiring up to 50% less water for backwash. The nature of the micro-sand and cross-flow technology has aided in the creation of a system that occupies and weighs up to 80% less than traditional media filters. Horizontally stacked vessels are now available, doubling the filtration capacity within the same footprint.

Most Common Configurations Full Flow Filtration Full flow filtration is used to filter 100 percent of the systems circulating water. It utilizes a filtration system installed after the cooling tower on the discharge side of the pump. This filter continuously filters the entire system flow, meaning that the filter must be sized to handle the system’s design flow rate. Full flow filtration reduces and chiller maintenance significantly and improves the operating cycles of the equipment as well. Full flow filtration is the preferred method of filtration but is not cost effective for systems with high flow rates. Full flow systems cannot run and be cleaned at the same time, which means that maintenance requires planned downtime.

Side Stream Filtration Side stream filtration is used to filter a portion of the systems circulating water, removing debris and particles that are adversely affecting the cooling loop and its components (heat exchangers, and more). Over time, filtering 10% - 20% of the cooling loop flow results in the filtration of the total volume of water every 12 – 72 hours. The filtration rate will highly depend on the application and filtration technology at hand. Side stream filtration technology generally falls into the following categories: screen filters, centrifugal filters, bag & cartridge filters, sand/media filters and high efficiency media filters. Each filter technology is evaluated based on their performance in filtering Filtered Water to Manifold of Turbulator Nozzles fine particulate (ranging from 1 - 50 microns).

Basin Sweeping Basin Sweeping is used to filter a portion of the systems circulating water, removing debris and particles and returning the filtered water to the cold-water basin of the cooling tower through turbulator eductor nozzles placed in the basin. The filtered water returned Filtra�on Skid Eliminates to the basin is used to ‘sweep’ the dirt towards the filtration system inlet thus keeping the Efficiency Robbing Par�culate Basin Drain to 45° motion in twoT urbulatordimensions. Nozzles Filtra�on Skid Inlet Prevent Se�ling of solids from ever entering the cooling system. Most applications will benefit from a basin Par�culate to Maintain a Clean Basin sweeping system from both an efficiency, and an economic standpoint. Basin sweeping systems can work as standalone or paired with full flow and side stream filtration. The eductor can be locked at any position.

Page - 11 // Electrolytic Scale Remover (ESR)

Ensavior introduces the Electrolytic Scale Remover (ESR) system. The ESR system helps remove scale by electrolytic operation without adding chemicals (Zero Chemical).

Open and closed loop water circuits encounter three main problems: Scale, Corrosion, Bio-fouling and Algae

The following operational issues arise from these problems: • Increase in electricity consumption • Increase of water consumption • Reduced efficiency of the cooling tower • Health hazards • Shorter life of equipment

Technical & Chemical Process • By applying electrical power between the anode and the cathode, a chemical reaction is activated, and electrolysis process takes place. Water from the cooling tower basin is circulated through the electrolytic scale remover reactor. • Due to the electrolysis process, the dissolved calcium molecules get deposited on the cathode and the water returns to the process. • The chemical reaction on ESR cathode is as shown: • The main ingredients of scale in water systems (MgCO3, CaCO3, Mg(OH)2, SiO2) are almost completely removed from the water in this process. • Chlorine in water forms hypochlorous acid (HOCl) and hydrochloric acid (HCL). When this solution of HOCl and HCL reacts for a sufficient time with and excess of limestone (calcium carbonate) the reaction is:

Calcium chloride and carbon dioxide solubility are rather high, so these reactions of HOCl and HCl would tend to decompose calcium carbonate scale to form rather soluble calcium chloride. • The reaction of HCl with bicarbonate alkalinity results in a reduction of alkalinity of about a 1 ppm HOCl to 1 ppm HCO3- ratio. This has a rather insignificant effect on pH, but any pH reduction aids the calcium carbonate resolution rate. • Oxidants generated mitigate Corrosion, Bio-fouling, Micro Organism growth, Scaling and spread of Airborne Bacteria.

Technical Innovation • Proprietary Ultra-Short Pulsed DC Technology • Highly Efficient Oxidation - Reduction Process • Cold Electrochemical Activation System • Functionalized Electrode Design • Self-Cleaning Electrodes

Potential Benefits of Electrolytic Scale Remover ESR can take care of …. • 100% savings on chemicals. • Scale formation, • No need of softeners. • Algae formation, • 60 to 70% savings on blow-down water. • Slime formation, • 10 to 50% savings on labor cost. • Waterborne Bacterial growth, • 20 to 40% of water savings. • Disinfection (prevent Legionella), • 05 to 15% of energy savings of cooling . • Alkaline pH environment that • 02 to 30% energy savings on cooling energy. prevents corrosion • 02 to 20% saving on energy in power plants.

Page - 13 // Chilled Water Thermal Storage

FTEnE Korea, an ISO-9001 and IS0-14001 company, is engaged in design and promotion of Thermal Energy Storage Systems (Water based) with special focus on Chilled Water Thermal Energy Storage System (CHW-TES). This system utilizes only the of water for cooling energy storage in a chilled water storage tank and discharges the stored coldness for air-conditioning during the on-peak time.

The key technology of CW Storage system is the diffuser design which ensures thermal stratification of chilled water and warm water by density difference. This is a state of the art technology recommended in ASHRAE’s design guide. They have a long history of installation around the world including U.S.A., Japan, Korea and Middle-East Asia

Some key features of Chilled Water Thermal Energy Storage Cooling • Lowest initial investment cost • 30-40% energy saving by utilizing conventional chillers whose efficiency is higher than low temperature chillers. • Simple system with easy controls without additional heat exchangers and less equipment • Efficiency of discharging coldness is very high • Easy to convert conventional system into CHW-TES system by adding only chilled water storage tank • Environment friendly system, free from brine • Storage water can be utilized for fire-fighting in emergency

Thermal energy storage systems that separate warm and chilled water by means of gravitational stratification are being suggested in the cooling of buildings, because they can be easily retrofitted into existing chilled-water systems. The performance of a stratified storage depends upon the ability to store warm and chilled water with little incursion of temperatures during its storage. The interfacial zone between the warm and chilled water in the storage tank, where there is a large temperature gradient, is called the thermocline, and its thickness should be as small as possible. The increase in thermocline thickness with time is a measure of stratification decay in the chilled-water storage system and leads to the loss of cooling capacity. Stratification in a storage tank depends mainly on the temperature difference of the inlet and outlet.

How a TES System Works? The system allows the TES tank to be ‘charged’ and ‘discharged’ of chilled water on a continuous basis, see the schematic representation of Charging and Discharging Cycles.

Charge cycle The chilled water at a desired temperature is charged through the bottom diffuser into the tank at the same rate as the warm water is displaced through the top of the storage tank. The thermocline forms at the bottom and slowly moves up to the top as charging takes place. During charging, the available cooling capacity of the charged water degrades due to mixing of the charge with the stored water. This is in addition to the thermal diffusion, axial wall conduction and heat gains from the ambient. The thermal degradation due to mixing reduces with decreasing charge flow rate. Therefore, at very low charge flow rates, the thermal degradation is mainly a result of a combination of heat gain from ambient, thermal diffusion and axial wall conduction.

Discharge Cycle In a discharge cycle, the storage tank initially filled with chilled water is discharged through the bottom diffuser and returned to the tank through the diffuser at the top, after it is passed through the load. The thermocline forms at the top initially and slowly moves down to the bottom at the end of a discharge cycle.

Page - 14 // Detailed Computational (CFD) Analysis CFD analysis provide insights into: • Prediction of the discharge water temperature with time. • Prediction and optimization of thermocline thickness. • Analysis of diffuser design on the performance of the tank. • Design and optimization of supply and return diffusers. CFD Analysis of Charging Operation • Three dimensional visualization of water flow patterns in the tank. • Visualization location and thickness of thermocline with time.

How It Helps? Reduces Capital Costs & More... Traditional air-conditioning systems operate during the day to meet the cooling demands and remain idle at night. High capital cost and high capacity chillers are then selected to CFD Analysis of Discharging Operation satisfy the maximum demand, which occurs only for a few hours per year, and thus spend the majority of their operational life at reduced capacity and low efficiency. Using stored energy, the TES supports the peak cooling demand, enabling a significant reduction in installed chiller capacity (up to 70%), and thus allowing the usage of lower cost and capacity chillers.

Lowers Operational Costs & More... The TES system helps lower Operational Costs by enabling the shifting of energy consumption of chillers from high cost hours to low cost hours by utilising stored energy during high cost periods and storing ‘cooling’ energy by running the chiller during low cost hours. Further, as lower capacity chillers may be used, the chiller can run at optimal capacity thereby raising its efficiency level.

Efficient Backup Energy Source Most critical application air-conditioning systems require some form of standby, or backup facility to protect against system failures, which can prove to be extremely costly. The TES is an ideal and efficient solution for these applications. The TES offers rapid response backup in the form of an independent, static technology solution which ensures the highest degree of reliability. In times of uncertain power availability, the TES system can provide non-stop cooling, even without grid power.

UVPCO often utilizes a honeycomb configured, reactor coated with titanium dioxide (TiO2 or titania) as the photo-oxidative catalyst. This design has a high conversion rate with low pressure drop making it suitable for use in building HVAC systems. The coated screen is irradiated with UV light near 254 nm UVC. Air containing organic pollutants flows through the screen , where the VOCs adsorb on the catalyst. The UV light interacting with the catalyst in the presence of oxygen and water vapor, produces hydroxyl radicals. Hydroxyl radicals are highly chemically reactive and, in-turn, breakdown the adsorbed VOCs, ideally producing only carbon dioxide and water as bye products.

Introduction Ultra Violet Germicidal Irradiation (UVGI) is the use of ultraviolet (UV) energy to kill or inactivate microbes (viral, bacterial and fungal species).

UV energy attacks the DNA of a living cell, penetrating the cell membrane, breaking the DNA structure of the micro-organism, inhibiting reproduction. UVC is effective in destroying biological contaminants and odours such as mold, bacteria and viruses. The Centers for Disease Control (CDC) recommends this method for destroying viruses such as tuberculosis.

The sun delivers specific UV wavelengths that destroy and deactivate chemical contaminants that are introduced into the atmosphere. Our UV lamp produces the same UV wavelength the sun produces. UVC (Germicidal 254nm) and UVV (Oxidizing 187nm) produced using quartz glass.

UVV (Vacuum UV) is used for oxidization; this is the portion of the lamp that destroys chemicals and odours, such as cigarette smoke, VOC’s, diesel fumes, formaldehyde, amongst others. Both UV wavelengths work together to destroy thousands of biological and chemical contaminants that continually circulate within the building. Depending on the application, we use UVC, UVV, or a combination of both wave lengths to achieve the desired results.

Applications of UVGI • Air-conditioned Offices and Residential Buildings • Hotels: Rooms, Restaurants, Sewage Treatment Plants and Kitchen Exhausts • Hospitals: Patient Rooms, Operation Theatres and Laboratories • Manufacturing facilities of Foods and Pharmaceutical products • Cold storage and Refrigerated spaces for storing of fruits, flowers and vegetables etc. • Industrial Kitchens, Auditoriums, Airports, Cinema Halls and Shopping Malls

UVGI (Ultra Violet Germicidal Irradiation) system is installed in Air Handling Units of HVAC. The reason for installing this is to overcome the following usual problems encountered with air conditioning and systems, commissioned without any UVGI.

Increasing Electricity Consumption The condensation of moisture around the cooling coils creates growth of algae, mold, mildew bacteria and viruses. Thus reducing the heat transfer efficiency and air flow of the AHU which in turn increases the power consumption. Coil Before UVC Deteriorating Indoor Air Quality (IAQ) The contamination of the air while passing over the coil and contamination from the work place deteriorates the IAQ leading to Sick Building Syndrome and increased sickness of the inhabitants of the building. In case of cold storage, it leads to contamination and deterioration of food products.

Increased Operation & Maintenance cost As a result contamination of coils, difficulties are experienced to maintain clean and contamination free air passage.

Improved Cleanliness, Eliminated Maintenance & Cleaning of Cooling Coils The cleaning of cooling coil is practically eliminated after installation of UVGI, thereby Coil After UVC reducing maintenance cost and eliminating down-time of the air conditioning system.

For Retrofit and New Projects • Can be installed in existing AHU without disturbing or changing anything in the AHU • Can also be incorporated in the design stage at the time of new projects

Air Disinfection and Stench Removal A mounted Ultra Violet (UV) based product designed for original fitment or retrofitting in ducts usually for the purpose of eliminating bad odours of kitchen exhaust, toilet exhausts, sewage treatment plant etc. This product finds wide application and acceptance in hotels and hospitality industry as well as for hospitals and industrial canteens, public toilets etc.

How Does it Work? Bad odours are largely caused by volatile compounds(VOC’s).The UV lamps used in ducts are very special and capable of producing ozone by a photochemical reaction along with normal germicidal 254nm UV light. Ozone oxidizes VOC’s and converts them into traces of water and carbon dioxide, while 254nm UV kills bacteria and other microbes. Thus Ozone destroys odours and 254nm UV disinfects the air. AHU Mounted System Germicidal UVC technology using ozone-producing lamps is an efficient and cost- effective method to prevent odor issues and to meet strict official regulations. Ozone safely reacts with the odor-causing agent (VOC’s), such as ammonia, sulfides, and mercaptans, breaking it into less complex molecules through a process called oxidation.

Ambient air is directed through the system’s UV chamber. The ultraviolet light acts as a catalyst, breaking down the ambient oxygen and water vapor molecules into the short- lived oxygen and hydroxyl free radicals. The end result is an effective and immediate gas breakdown, with very little by product. Ozone is a powerful oxidant and bactericide, which destroys organic molecules in the air, thus eliminating any unpleasant odor, as well as any impurities in the air. Duct Mounted System

ESPAIRTM has been servicing the Commercial , IAQ and Industrial Ventilation market since 1995. They have an extensive list of fully satisfied customers and end-users; a legacy which is second to none. It is intimate understanding of the product, the industry and focus on customer service, which has resulted in being the leading supplier of Commercial and Industrial Ventilation Systems based on ‘Electrostatic Precipitation’ also known as Dry Scrubber.

The Smoke-Eater is ideal for removal of grease and smoke from commercial kitchens and also smoke, fumes and oil/ mist from industrial processes. It is a proven electrostatic precipitation technique to remove smoke, grease, mist and other particulates from the air.

Principle of Operation Contaminated air to be cleaned from the process is drawn into Smoke-Eater by fan/ blower through a washable metal mesh pre¬filter which traps large size contaminants, then it passes through lonizer-Collector Cells.

Ionizing – Collector Cells comprise of two parts, one is lonizer section and the other is Collection section. Contaminated air first passes through lonizer section wherein ionizers (tungsten wire or SS spiked blades) which are supplied with 12 kVDC voltage creates a high intensity field where the particulate matter in the air becomes electrically positively charged.

These positively charged particles then pass through a collector plate section made up of a series of equally spaced parallel plates. Each alternate plate is charged with 6 kVDC the same polarity as the particles, which repel, while the interleaving plates are grounded, which attract and collect.

The ionizer-collector cells, pre-filters and post-filters are removed through the side access door for periodic cleaning of the contaminants.

Smoke-Eater removes extremely small particulate matter from the air stream with relatively no resistance to air flow, due to the open area of the collecting elements. Low resistance is maintained from start to the completion of the collection cycle. Unit operates in the higher efficiency collection range, upward of 90-95% DOP Method on particles ranging in size from 10 microns down to 0.01 microns in size.

Durable, Compact, Modular Cabinetry – The housing is constructed using 16-gauge zinc-coated steel. All welds and the finished area of welds are treated with a rust inhibiting coating to ensure long life. Cabinet finish is a durable industrial grade semi-gloss baked epoxy-polyester powder coating which is not less than 3 mil thick. All doors are gasketed to prevent air and water leakages.

Design is modular in nature to use in combination of multiple units for handle exact amount of exhaust air volume.

Add On – Activated Carbon Filters and Ozone forming UV Lamps can also be provided with the units as per requirement for light odor abatement.

Adsorber Module ‘Odor Remover’ – Adsorber Modules are for heavy odors abatement and are designed to mate Smoke-Eater modules consisting of Activated Carbon/Potassium Permanganate Cassettes arranged in V formation/Cylindrical Canister.

Ozone Generator ‘Ozonia’ – Ozone Generators create and inject Ozone into the exhaust air ducts to get rid or odors, VOC and grease particles. Also helps to keep the ducts free from grease.

Automatic Wash ‘Autokleen’ – Intelligent PLC controlled, in-place automatic wash module for cleaning. Reduces the frequency of maintenance.

Exhaust Air Fan ‘Air Drive’ – Grease-Rated Fan Package with complete accessories for commercial kitchen exhaust application. Various options available suiting to site conditions.

Electronic The Espair™ Eco Stream EAF Series Electronic Air Filters are designed to remove Indoor Air Pollutants like smoke, dust, pollen, tiny microorganisms and fumes from the indoor spaces: restaurants, bars, offices, hotels & hospitals, public gathering areas, industries, waiting rooms, designated smoking areas, and more. These filters are also act as guard filter to HEPA filters in any typical clean-room or hospital application. Polluted air does not just harm the health of occupants; it is also harmful to HVAC equipment. Dirty air particles stick to the internal components of the system, damaging internal motors and fans and lead to poor heat transfer on the system’s coils. Electronic air filters keep the system clean and operating at peak energy efficiency.

The average central air conditioning system typically performs some form of air cleaning; such systems capture only large particles and are not efficient enough to capture the microscopic airborne pollutants and particles that cause asthma and allergies. Electronic air filters capture up to 95% of airborne pollutants as small as 0.1 micron tocreate clean air. These units are installed in AHU Return Air Plenum or return air ducts, passing recirculated air through the air cleaner. The air is purified and recycled back to the indoor spaces.

Working Principle Electronic Air Filters include two parts: the charging and the collecting sections. In the charging section, the incoming smoke, dust and other particulates pass by ionizer wires which impart a positive electrical charge to these contaminants. The charged contaminant particles then pass into a collector plate section made up of a series of equally spaced parallel plates. Each alternate plate is charged with the same polarity as the particles, which repel, while the interleaving plates are grounded, which attract and collect the contaminants. The contaminants are held in these plates until they are washed away. Air cleaners trap dry particulates like dust, dirt, lint pollens, haze particles etc.

MSA, an American company known as ‘The Safety Company’ because of its precision technology to make safety the highest quality so that people can work anywhere in the world in the safest possible environment. It’s core products include self-contained breathing apparatus, fixed gas and flame detection systems, portable gas detection instruments and personal protection products for fire, rescue and fall.

Gas leak detection is the process of identifying potentially hazardous gas leaks by sensors. These sensors usually employ an audible alarm to alert people when a dangerous gas has been detected and can interface with a control system so as to automatically shut down a process or start a ventilation system. Which variant of gas detection is best; depends on location, preferences and different sources that may pose a danger to human/animal life. Gas detectors can be used to detect combustible, flammable and toxic gases, and oxygen depletion. These devices are used widely in industry and can be found in locations, such as on oil rigs, to monitor manufacture processes, HVAC plant rooms, water treatment plants, sewage systems and firefighting etc. Exposure to toxic gases can also occur in operations such as painting, fumigation, fuel filling, construction, excavation of contaminated soils, landfill operations, entering confined spaces, etc.

Common sensors include combustible gas sensors, photoionization detectors, infrared point sensors, ultrasonic sensors, electrochemical gas sensors, and semiconductor sensors. More recently, infrared imaging sensors have come into use.

The HVAC industry requires a wide variety of gas detection needs. From boiler rooms, battery rooms, engineering and research labs, and transportation maintenance facilities to many other industrial building and facility applications, each environment has its own monitoring needs. To enable personnel to work safely within these environments, monitoring of toxic gases, oxygen enrichment and deficiency and combustible gases is necessary.
