Industrial make-up water quality is bad in Shanghai Petro-Chemical Area. Since the circulating cooling water system has to run at 4 ~ 6 times of concentration cycles and to assure the heat transfer exchangers to run for long period of 3 ~ 5 years continuously, contradictions with each other occurs. Reverse osmosis technology has been used to improve the quality of the fresh make-up water in the circulating cooling water system. On the premise of not changing the index of the water quality, the cycles of concentration have been increased greatly. So water saving and cost lowering are realized. The high cycles of concentration water treatment programme and on-line chemical cleaning once per year can increase the cycles of concentration, improve the water qaulity, and reduce the accumu lation of the deposits. Remarkable results have been obtained.
