Abstract:

This paper introduces the present running situation of the circulating cooling water in the Ammonia Plant of Dahua Group and the conditions of fresh water provided and saved in Dalian.Now we use the technologies of the desalination of the ED,getting rid of the suspending materials with the highly efficient surface membrane filter and killing the bacteria of ozone to reform circulating cooling water system of the ammonia plant.The destinations of increasing the profit,decreasing the sewage and saving the fresh water have been realized.

Key words: ED, highly efficient surface membrane filter, the machine of ozone circulating cooling water system, saving water
