Abstract

See full text

A water conditioning system for evaporative cooling systems reduces operating costs and microbial contamination by introducing positively charged copper-silver ions into water used as a working fluid. Some of the recirculating water is also passed through a magnetic conditioner to increase its conductivity. By concentrating the total dissolved solids (TDS) in a portion of the water to be expelled, the remaining system water plus new make-up water added contains far lower TDS, reducing health risks, maintenance costs, corrosion, and scaling, and extending service life of replaceable filter elements and system machinery. Recovering non-chemically treated cooling tower bleed water with commercial scale nanofiltration water polishing equipment and returning that polished water back to the cooling tower water basin reduces the make-up water required, and may achieve 70% or greater reduction in sewer fees for tower bleed water, along with increased cycles of concentration further reducing requirement for make-up water.
