Abstract:

A process and system are provided for controlling hardness in recirculated cooling water, wherein chemical addition is independent of pH determination. Hardness is determined in a make-up water stream provided to a cooling water system. Chelant is continuously added to the make-up water stream, the amount of chelant being a function of the make-up water hardness. A side stream is circulated from the cooling water system to a reactor. A conditioner is added to the reactor based on the amount of chelant. The conditioned side stream is retained within the reactor to precipitate a percentage of suspended solids, and a portion of the precipitated solids are removed as necessary to maintain a fluid bed level. A clarified water stream is withdrawn from the reactor and returned to the cooling water system circulation. A chelant concentration of from 600 to 800 ppm is maintained in the system.
