A new cooling water treatment program, which allows the recycling of cooling water at high cycles with the no pH control, has been developed. The treatment is very cost effective and unique in that each component complements the performance of the other components for scale and corrosion inhibition. Results from static laboratory studies, as well as from a pilot cooling heat exchanger unit, and a case history from an East Coast Steel Mill, are presented.
