What should be paid attention to when cleaning flat ceramic filtration membrane?

Normally, the permeate flux of the polluted flat ceramic filtration membrane would be decreased, and it need to be cleaned for restoring flux and separation performance. Recent years, many cleaning methods have been proposed to remove the pollution of ceramic filtration membrane, so what should we pay attention to when cleaning flat ceramic filtration membrane?

First stage: acid washing, the ceramic membrane is acid washed with nitric acid solution as the acid washing agent at room temperature. When the acid washing processing, the clear solution filtered is used as the backwash solution to backwash the ceramic membrane; Second stage: alkali washing, the ceramic membrane is alkaline washed with sodium hydroxide solution as the alkali washing agent. During the process, the clear solution filtered is used as the backwash solution to backwash the ceramic membrane.

After acid and alkali circulation cleaning, the membrane unit can be cleaned with clean water. Under the action of acid and alkali solution, the ceramic membrane unit can be cleaned quickly. The cleaning time is greatly shortened and a lot of resources are saved on the same cleaning effect.
