Electrochemical cooling water treatment: a new strategy for control of hardness, scale, sludge and reducing water usage.

Author(s) : BECKER H. A., COHEN J. J., ZDUNEK A. D.

Summary

Fouling due to calcium salts present in hard water has proven historically troublesome in metal plating, chlor-alkali production, and other electrolytic operations. It is perhaps ironic, this classical nuisance includes mechanisms for effective control of troublesome deposition throughout large, real-world recirculating water systems; effectively establishing a new water treatment strategy of environmental and economic benefit. An electrolytic process can be employed for evaporative cooling systems of all types to generate in-situ chemistry and physical activity totally controlling hard-water deposits and minimizing both corrosion and biofouling. This is accomplished without classical chemical treatment or water conditioning while also allowing substantial reduction in cooling system bleed-off.
