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. Our cooling tower water treatment programs are designed to provide proper chemical water treatment and preventive maintenance of open recirculating once through and closed recirculating cooling tower systems. 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. 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.

5 water is used around the world in industrial. Thus that s all the chemicals used in cooling tower water treatment. Improved heat transfer efficiency. 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.

Differences between acid base and salt. 5 4 chilled system treatment 33 6. A cooling tower is a heat rejection device that rejects waste heat to the atmosphere through the cooling of a water stream to a lower temperature. By fans into the cooling tower and up through the flow of falling water in the cooling tower.

Cooling water tower system benefits. 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. If cooling tower water is untreated fouling scaling organic compound and corrosion can form and that reduces plant productivity. You might want to read.

Selecting the proper water treatment program depends on the size and location of your cooling tower. Cooling is accomplished through the latent heat of vaporization. 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.
