  • Optidose polymer

    Maintaining a minimum concentration of an effective dispersant polymer is crucial in an alkaline cooling water treatment program. The problem is knowing exactly how much polymer is available in the cooling water to combat fouling and corrosion of heat transfer equipment. Many years of research and effort have gone into the development of a method for tracing the concentration of polymers. Rohm ...
