A method for cleaning ceramic membranes

The present invention relates to a method for cleaning ceramic membranes is: Under normal conditions, the pickling stage, a solution of nitric acid pickling ceramic membrane lotion, in the process of pickling in ceramic membrane filtration of the supernatant trans red solution, the set of the ceramic film recoil; in caustic phase with sodium hydroxide solution to a ceramic membrane caustic alkali wash, caustic in the process of membrane filtration to the ceramic supernatant solution is the kickback , the set of the ceramic film recoil; pickling with caustic cleaning cycle, washing with water to wash the membrane module after passing the clean water cleaning membrane. Solves the premise at room temperature, under the action of an acid, alkali solution, and using an acid, a base of the membrane module supernatant recoil, the rapid clean ceramic membrane, reached the same cleaning effect, greatly reducing the cleaning time, save a lot of resources.
