The analysis and treatment on

 membrane fouling of ultra filtration device

Abstract: In this paper, the basic principle and characteristic of Ultrafiltration device in plant flue water treatment are introduced. The reason on membrane fouling of Ultrafiltration device in operation is pointed out.Proposal is made for the solvement to the pollution of Ultrafiltration device by chemical cleaning.The importance is emphasized that the characterizations of film are  restored by chemical cleaning.

Key words: Ultrafiltration; membrane fouling; chemical cleaning
