Alternative cooling tower water treatment methods.

Author(s) : WILSEY C. A.

Summary

The factors that contribute to proper water balance include total alkalinity, calcium hardness, and pH. In order to keep the cooling tower from scaling or corroding, a manipulation of these components is often necessary. This has traditionally been achieved with the use of chemicals, including but not limited to the following : acid, soda ash, sodium bicarbonate, calcium bicarbonate, algicide, and bactericide. Extensive research has shown that a balanced water system can also be achieved by using the proper combination of copper with a known halogen. Microbiologists have determined that a small amount of copper acting as a supplement to chlorine at 0.4 ppm, has the same efficiency as 2 ppm free chlorine. Therefore, by using a combination of components and procedures, the desired results can still be achieved. More details are given.
