The need for increased water conservation, improved environmental profile and enhanced safety through the minimization/elimination of acid feed in open evaporative cooling water systems has prompted the development of a new, novel series of cooling water treatment programs. These new programs were designed to handle low through high hardness, alkaline cooling waters and provide increased cycles of concentration without the need for acid feed. The programs utilize a new biodegradable carboxylic antiscalant and lower total phosphorus levels than traditional cooling water treatment programs. A description of the new technology and case histories demonstrating field efficacy will be presented.
