Field Experience with a New, Novel Series of High Performance, Environmentally Friendly Cooling Water Treatment Programs

摘要

The need for improved corrosion/scale control performance, enhanced environmental profile, increased safety through the minimization/elimination of acid feed and optimized water conservation in open evaporative cooling water systems has prompted the development of a new, novel series of cooling water treatment programs. These programs were designed to cost-effectively treat low through high hardness, alkaline cooling waters and provide increased cycles of concentration without the need for acid feed through the use of a new biodegradable carboxylic antiscalant and lower total phosphorus levels than traditionally used in cooling water treatment programs. A description of the new technology and case histories demonstrating field efficacy are presented.
