SUBMERGED MEMBRANE MODULE CLEANING SYSTEM FOR WASTE WATER TREATMENT AND CLEANING METHOD OF THE SAME

摘要

PURPOSE: A system and a method for washing a membrane module for water treatment are provided to wash various foreign materials accumulated in a membrane using water produced by the membrane without chemicals. CONSTITUTION: A system for washing a membrane module for water treatment comprises: an electrolytic water generator(10), an electrolytic water storage tank(20), and an electrolytic water supply unit(70). The electrolytic water generator performs electrolysis of foreign material-removed water into alkali electrolytic water and acid electrolytic water. The electrolytic water storage tank separately stores the alkali electrolytic water and acid electrolytic water. The electrolytic water supply unit supplies the stored alkali electrolytic water and acid electrolytic water to the membrane module. The membrane module is washed using the alkali electrolytic water when the membrane module is contaminated by organic materials. The membrane module is washed using the acid electrolytic water when the membrane module is contaminated by inorganic materials.
