Chemical and sludge free water treatment process

摘要

Abstract: A process imparting the treatment of industrial water, especially thermal power plant water, providing multiple streams of water products at qualities superior to that achieved by chemical clarifier based processes without the burdens of chemical consumption and sludge generation. The process employs staged filtration means 10, 12 singly pressured from source 2 via a side-stream 8 of a cooling tower make-up water source to generate a medium grade filtrate 18 for employ as a plant service and fire protection water source, a medium grade reject 20 for use as a primary water source for make-up to a cooling tower and a high quality permeate stream 22 for employ as a water source 28 for a demineralization system and a water source 24 for a potable water system.
