ADVANCED WATER TREATMENT SYSTEM WITH FOULING CONTROL USING SURPLUS RESIDUAL OZONE

摘要

The present invention relates to an advanced water treatment system capable of controlling a contamination of a separation membrane by using surplus ozone, comprising: an ozone processing unit for processing treated water with ozone by injecting ozone into the treated water; an agglomeration unit connected to at least one from the front and rear ends of the ozone processing unit, and agglomerating the treated water which is treated with a coagulant; a membrane filtration unit for filtering the treated water which has passed through the ozone processing unit and the agglomeration unit through a separation membrane; and an ozone backwash unit for generating ozone wash water by receiving surplus ozone generated from the ozone processing unit and dissolving the same in a solution, and for backwashing the separation membrane of the membrane filtration unit by using the ozone wash water. Accordingly, it is possible to recycle surplus ozone and to reduce the surplus ozone by removing a contamination of the separation membrane by using the surplus ozone from the ozone generated for an ozone processing in an advanced water treatment system wherein a separation membrane is used.
