Drinking Water Treatment

Abstract

In this application, hydrogen peroxide is applied in a slug mode, where it is fed into the cooling system and recirculated over a period of 4-8 hours. Performing an occasional cleaning of a cooling tower with hydrogen peroxide can remove biological buildup on the surfaces and within the tower’s fill, resulting in improved heat transfer efficiency. By removing excess biofouling, hydrogen peroxide also improves the efficiency of the ongoing cooling system treatment program, by reducing demand for commonly used biocides like bleach (sodium hypochlorite), bromine and non-oxidizers.
