| Abstract: | In order to reuse the blowdown water from circulating water in thermal power plant,the reverse osmosis system is being used for deionization with ultrafiltration as pretreatment.According to characteristics of the blowdown water,the fouling reasons for ultrafiltration membrane are analyzed,and the fouling characteristics,the fouling types and the affecting factor for ultrafiltration membrane are also discussed.Then the key techniques of chemical clean methods for fouling membrane are presented,they can eliminate the membrane fouling and recover the separation function. |
