Abstract:

Ultrafiltration system is widely used in chemical water production in thermal power plant. How to prevent the ultrafiltration system from breaking down due to the UF membrane pollution and fouling during operation is an important work of daily operation control of UF system. The fault failure of sudden fouling in the ultrafiltration system was studied and analyzed, and the solution and implementation measures for chemical cleaning were formulated in time. The importance of chemical cleaning to restore membrane performance was further demonstrated through cleaning practice, so as to find suitable methods for pollution control in the future.

Key words: ultrafiltration, membrane fouling, chemical cleaning
