Cooling Tower Water Treatment Chemicals Pdf

For industries using a cooling tower some type of cooling tower water treatment system is necessary to ensure long equipment service life and efficient performance.

Cooling tower water treatment chemicals pdf. Here are the basic types. Chemicals used to control microbial populations can be grouped in three general classes based. Water treatment the purpose of a cooling tower is to remove the heat generated by an hvac system cooling of compressor refrigerant and heat generated by the compressor itself. Treatment of cooling water will be different depending upon the kind of system in use.

Cooling tower makeup water. 35 6 3 treatment for scale control 36 6 4 treatment for corrosion control 37 6 5 blowdown 38 6 6 treatment to control algae and slime growths 38. For each pound 121 gallons of water that a cooling tower evaporates it removes about 1 000. There are lots of advantages when industries or companies are using cooling water tower system.

Cooling is accomplished through the latent heat of vaporization. 5 water is used around the world in industrial. If cooling tower water is untreated fouling scaling organic compound and corrosion can form and that reduces plant productivity. Cooling water tower system benefits.

Differences between acid base and salt. A robust scale corrosion inhibitor program should be accompanied by a biocide program to fit your needs. 5 4 chilled system treatment 33 6. Cooling towers may either use the evaporation of water to remove process heat and cool the working fluid to near the wet bulb air temperature or in the case of closed circuit dry cooling towers rely solely on air to cool the working fluid to near.

Drift eliminators are installed to prevent water entrained in the air from leaving the system. Cooling towers and treatment 6 1 chemical feed equipment 34 6 2 calculation of cooling tower treatment and blowdown. By fans into the cooling tower and up through the flow of falling water in the cooling tower. Cooling tower chemicals will help maintain efficiency by preventing corrosion scale deposition and biofilm growth.

Thus that s all the chemicals used in cooling tower water treatment. Treatment chemicals for high medium low capacity cooling towers. The term induced draft denotes that air is drawn by fans through the flow of falling water and up and out of the cooling tower. Even with the best chemical treatment program impurities in the cooling tower can only be allowed to accumulate to a certain level before the scaling potential overwhelms the chemical treatment.

Selecting the proper water treatment program depends on the size and location of your cooling tower. Improved heat transfer efficiency.
