Abstract:This article discusses emphatically the preparation techniques of diatomite composite membrane,using the dippinc method to apply a film of diatomite on the a-AlO. microfiltration membrane.The results show that the diatomite film calcined at low temperature can be peeled off to realize the repetitive usage of a-AlO: membrane under backwash effects.
Keywords: dipping method,diatomite,microfiltration composite membrane
