We are authorized dealer of NCH Corporation, Texas, USA. COOLING TOWER WATER TREATMENT SOLUTIONS NCH has provided quality full-service water treatment to customers since 1919. Since then, we have developed a unique combination of knowledge and experience in exceptional service world-wide. We deliver environmentally responsible and economically profitable solutions that help keep boiler, cooling, process, and wastewater systems running at peak efficiency. The Benefits of Cooling Tower Filtration Information & Article During their normal operation, cooling towers remove large quantifies of dirt, dust, pollen, bacteria, stack emissions and other airborne matter from the surrounding air. In fact, research has shown that in some cases, a mere 200 ton cooling tower can accumulate more than 600 pounds of suspended matter from the air and make-up water over the course of a year! Unless the proper treatment measures are taken, these contaminants can cause serious waterside problems. In many cases, a properly designed and sized filter will be a cost effective component of your cooling tower treatment program. The benefits of filtration to help maintain clean water in a cooling tower system include: Energy Savings - By removing suspended solids from the recirculating water, the potential for deposits is significantly reduced. This helps keep cooling systems operating at maximum design efficiency. Improved Microbiological Control - Filtering bacteria and their food supply from the tower water significantly reduces the potential for microbiological growth, helps the biocide program work better, and can even lower biocide costs. The payback on improved microbiological control can be huge. A mere 0.005 of microbiological fouling in a 1000 ton chiller can increase annual electricity costs by $50,000! Longer Equipment Life - Maintaining clean tower water significantly reduces the potential for corrosion throughout the cooling system. Keeping the system surfaces clean allows the chemical inhibitors to more effectively form the desired protective film on metal surfaces. Filtration also helps prevent under-deposit corrosion. Reduced Maintenance - Unscheduled maintenance and downtime can be extremely costly. Maintaining clean recirculating water is not only sound preventive maintenance, it also reduces heat exchanger and tower cleaning costs. Chem-Aqua can engineer a wide range of filter solutions for your cooling tower, closed loop, and process systems. Contact us today to arrange for a comprehensive evaluation of your systems.

CLEANING & DESCALING OF ONE COOLING TOWER Cooling Tower Descaling Program Cooling Tower is a device which cools hot water from the machine and sends back in a circulatory pattern. Taking heat from the machines and rejecting the heat in to the atmosphere inside the cooling tower. Machines & Equipment using water from Cooling Tower to remove heat during working conditions. PROBLEM: BIOLOGICAL GROWTH / SLIME Biological Growth in Cooling Tower Fins leads to : 1. narrowing of gaps 2. reduced wind passage 3. ineffective cooling 4. fins going down Continuous accumulation of slime & sludge in water pipelines results in :

• reduced diameter

• slow passage of water

• excess heating on machine Scale formation in pipelines results in :

• reduced diameter of heat exchanger tubes

• reduced water flow rate

• insulation for heat transfer Rust & Corrosion results in :

• decreased heat transfer

• damage of heat exchanger tubes Bio-clean pack (BCP ) Treatment Bio Clean pack is unique compbination of various products specially formulated for effective descaling tasks. Pack A : Improves heat transfer in heat exchanging units, condenser coils and pipes. Pack B : Liquid boicide specially designed for acting at high pH. Pack C : Surfactant and penetrant for dispersing microbiological slimes and oil-type deposits in cooling tower systems. Benefits

• Killing and taking off biomass

• Economical and Effective at low dosage than conventional descalares

• Deep penetration and dispersion of biomass

• Superior corrosion inhibitor

• Organic acids protects metal surface from damage

• Low foaming

• Easy to feed. BIOCLEAN PACK Calculation- (1 BCP For Each 50TR ) Eg. For 300TR - 6BCPs 1 BIOCLEAN PACK (BCP) Contains NM40SUS - 5 LTRS ACTICHLOR - 4 LTRS AQUASPERSE - 1 LTRS DEFOAMER ( FC 101 ) - 1 LTR Procedure for using BCP Water PH should be in the range of 6.5- 7.5.- If not add fresh water and circulate and bring the Ph to optimal level of 7.5. Add NM40SUS and circulate for ten minutes. Add Actichlor and circulate for 10 minutes. Foaming may occur during the addition of Actichlor and Aquasperse. So add a maximum of 1 litre defoamer- with dilution 1: 5. Once all the above chemicals are dosed replace the water completely after 1- 3 days and change water completely. DESCALING PRODUCT CALCULATIONNM 50- 1LTR FOR EACH TRNM40 SUS(In case of occurrence of Stainless Steel)-2LTRS FOR EACH TRCBD 92- In case of occurrence of Aluminum) Upto 1.5% of total water quantity. Descaling Procedure with NM50 /NM40SUSSwitch off all equipments..Initially add 10% of the total quantity of Product into the cooling tower and circulate . The Ph of circulating water will be raising above 1(ranges from 3-4) depending on the intensity of the scale deposit). Add 10% of NM50 and again check the PH .This cycle should be continued until the PH remains constant at 1 for at least 3 hours continuously. Change water completely till Ph is neutral. Usage of BP 800 (Optional)After descaling with NM50, BP 800 can be used.to neutralize the circulating water to get a PH of 7- 8.5The quantity of BP 800 = NM50 Quantity x 0.2 litre.For ex. If the NM50 calculated above is 100 litre then BP800 required will be 20 litres.
