Water is typically the heat transfer medium used to dissipate the heat. A cooling tower water treatment system is an arrangement of technologies that remove damaging impurities from your cooling tower feed water circulation water and or blowdown. Cooling water treatment for controlling suspended solids algae growth etc. Powerpoint ppt presentation free to view.

The basics of cooling tower water treatment. A cooling tower uses a combination of heat and mass transfer evaporation to cool the water flowing through the tower. A tower cools water by evaporation by drawing high volume air across the water surface which transfers heat to the atmosphere. Range or delta t.

Ca hco3 2 normally present in all raw water breaks down to form relatively in soluble caco3. Water treatment plays vital role in cooling tower operation cooling tower maintenance can not run high unless the water is treated to prevent corrosion biological growth deposits and to protect the cooling tower wood from chemical attack. 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. What type of cooling tower you have open circulating once through or closed loop.

For each pound 121 gallons of water that a cooling tower evaporates it removes about 1 000 btu s from the liquid that remains. For large cooling towers especially power plants water treatment is the key area for energy conservation. A cooling tower is an evaporative type heat rejection device which extracts heat from the hot water and allows a small portion of circulating water to evaporate using latent and sensible heat which causes a significant cooling of rest of the circulating hot water. Wet bulb temperature is measured by the thermometer which is wrapped in a cloth called soak.

Utility w22 date. Wet bulb temperature of a. The function of a cooling tower is to dissipate heat from water cooled refrigeration air conditioning and industrial process systems. The specific configuration of your system will depend on several things including.
