Cooling Water Management Basic Principles and Technology By: Timothy Keister, CWT. Fellow, American Institute of Chemists Certified Water Technologist, Certificate #90. ProChemTech International, Inc. Apache Junction, AZ, and Brockway, Pennsylvania Distribution: General Issue: 08/30/01. Last revision: 03/08. I. INTRODUCTION. Evaporative Cooling towers are very popular as they provide the most cost effective Cooling technology for commercial air conditioning and industrial processes. However, drought conditions and increasing Water usage have combined to decrease the availability and increase the cost of the good quality, low hardness Water preferred for Cooling tower makeup use. At the same time, stricter environmental restrictions on effluent discharge have resulted in increased fees for disposal of Cooling tower blowdown to the sewers.
