Converting water hardness and silica to an environmentally desirable complex is the result of new cooling water treatment chemistry.  Over 95% of standard blowdown water is saved and reused providing significant water savings.  This unique chemical approach provides multimetal corrosion control.  The solubility of the new product is greater than 45% in ambient water. Solubility increases with temperature elevation.  The highly soluble hardness chemical undergoes a separate reaction forming a fluid concentrate to be removed intermittently.  Silica removal is maintained at less than 100 ppm. This new chemistry approach provides exceptional water savings in hard, alkaline cooling waters.
