Abstract

PURPOSE: To remove deposit on the surface or in a layer near the surface of a membrane in a non-oxidizing atmosphere without causing deterioration of the membrane by immersing and washing the membrane having no charge such as dializing membrane or electrolytic diaphragm in a washing solution containing surfactant, hydrazines, and H2O2 generating agent.
