Problem: Large quantities of water are used for cooling in industrial manufacturing. To prevent scaling, corrosion and biofilm in the cooling system, inhibitors and biocides are regularity dosed. Make-up water is continuously added to the system to balance the loss of water from evaporation. As water is added, the concentration of chemicals is diluted and the quality of water changes.

Power plants and paper mills use service water loops and mill water loops respectively for the cooling of lubricating, hydraulic, turbine and transformer oil. These cooling systems feature large, recirculating volumes of water which are treated with biocides, dispersants, and corrosion inhibitors. By comparison, refineries often use once through cooling water systems. The cooling water is taken from lakes, rivers, or the ocean and circulated once through the plant to cool processes. Large volumes of water are used to keep the return water temperature low enough to prevent adverse effects on the environment.
