Cleaning method of ceramic membrane

Ceramic membrane cleaning method: Under normal temperature conditions, in the pickling stage, the ceramic membrane is pickled with nitric acid solution as the pickling agent, and the clear liquid filtered by the ceramic membrane is used as the backwash solution during the pickling process. The ceramic membrane is backflushed; in the alkali washing stage, the ceramic membrane is alkali washed with sodium hydroxide solution as the alkali detergent, and the clear liquid filtered by the ceramic membrane is used as the backflushing solution during the alkali washing process. Carry out backflushing; after acid washing and alkaline washing cycle cleaning, the membrane module is changed to water washing after qualified cleaning, and then the membrane module is cleaned with water. It solves the problem that under the condition of normal temperature, under the action of acid and alkali solution, and using acid and alkali solution to backflush the membrane module, the ceramic membrane module can be cleaned quickly. Under the premise of achieving the same cleaning effect, Greatly shorten the cleaning time and save a lot of resources.
