Specifications include, but are not limited to: Maintain water quality for water systems to control corrosion and build-up of scale and biological growth for maximum efficiency of installed equipment without posing a hazard to operating personnel, the equipment or the environment.
•Base chemical treatment performance requirements on quality of water available at site, system equipment material characteristics and functional performance characteristics, operating personnel capabilities, and requirements and guidelines of authorities having jurisdiction.
•1.) Closed loop Systems: Maintain system essentially free of scale, corrosion, and fouling to sustain the following water characteristics: •a.) Conductivity: 3500 mm/cm maximum
•b.) PH: 8–11
•c.) Nitrite at 500 – 1000 ppm. If Nitrite is used, a biocide shall be added to provide adequate protection from biological growth within the closed system.
