Cooling Water Systems, Problems, Ozonation Treatment, and Ozone Demand Determination

Current technology and research concerning the ozonation applications for cooling water treatment are reviewed. The subjects covered in this chapter include (a) cooling systems and problems; (b) corrosion causes, detection, treatment, and control; (c) scaling, fouling, deposition treatment, and control; (d) microbiological contamination, cooling water treatment, and microbiological growth control; (e) ozonation for cooling water treatment, including fresh water coolant and sea water coolant; (f) potential cooling water production using ozonation; (g) parameters for ozonation applications, such as residence time, temperature, cycles of concentration, and dosage; (h) testing methods for ozone residual and ozone demand. Special emphasis is directed toward the use of ozonation as a cooling water treatment option and the recommended methods for the determination of ozone demand and chlorine demand. Summation includes recommendations for areas of research and calls for further research by researchers around the world.
