CLEANING SYSTEM OF SEPARATION MEMBRANE AND METHOD USING THE SAME

摘要

A system for cleaning a separation membrane of the present invention comprises: a membrane filtration tank installed with a separation membrane module; an ejector connected to the membrane filtration tank; an air compressor connected to the ejector; and a treated water tank for discharging the treated water when back washing or chemical washing by storing the treated water produced from the filtration tank. The cleaning of the separation membrane can be performed by operation of the ejector. The system for cleaning a separation membrane and the method for cleaning a separation membrane by using the same of the present invention are capable of significantly reducing an amount of power consumption by using the ejector and the air compressor while having a cleaning membrane at the same level in comparison with the conventional method for cleaning the separation membrane by using a back washing pump, increasing contact of membrane micropores with chemicals by circulating a chemical cleaning solution with the ejector, increasing chemical cleaning efficiency, and minimizing an amount of chemical used.
