Stressed Alkaline Cooling Water Deposit Control: High Temperature Suspended Solids and Iron ImpactsWater scarcity and environmental issues have necessitated operating cooling systems using poor quality feedwaters or changing process temperature conditions. Safety concerns have driven cooling system users to implemented alkaline treatment programs to facilitate acid feed reduction or elimination. Inorganic and/or organic phosphorus components in alkaline cooling water treatment (CWT) programs help prevent corrosion and scale formation. Collectively water conservation measures and alkaline CWT programs have increased potential metal-phosphate and/or phosphonate scale formation. Understanding deposit control polymers (DCP) perform under stressed conditions is essential for implementing alkaline CWT programs. This paper discusses CWT program metal-phosphate/phosphonate scale formation control efficacy when operating under stressed alkaline conditions (e.g. high temperatures suspended solids and iron).Keywords: deposit control polymers phosphate scale cooling water stress conditions particle dispersion phosphonate iron high temperature.

Key words: deposit control polymers, phosphate scale, cooling water, stress conditions, particle dispersion, phosphonate, iron, high temperature.
