The Control of pH & Oxidation Reduction Potential (ORP) in Cooling Tower Applications

From Walchem Corporation
 

 
The importance of keeping cooling tower water in proper chemical balance is becoming clearer. Cooling tower treatment control systems can limit scale formation to improve efficiency, limit corrosion to increase the service life of the cooling water system, and maintain a residual halogen level to reduce liability associated with biological growth,particularly Legionellae.
