WATER TREATMENT DEVICE HAVING SEPARATION MEMBRANE CLEANING FUNCTION AND METHOD FOR CLEANING SEPARATION MEMBRANE OF WATER TREATMENT DEVICE

摘要

The present invention relates to a water treatment device having a separation membrane cleaning function and a method for cleaning a separation membrane of the water treatment device, more specifically to a water treatment device which remarkably reduces the contamination speed of a separation membrane for delaying the reaching speed of transmembrane Pressure requiring the separation membrane cleaning, extends the separation membrane cleaning period, increases the lifetime of the separation membrane by the extension of the separation membrane cleaning period, and improves the operation efficiency of the water purification. The present invention can provide a separation membrane bio-reactor water treatment device capable of increasing the recovery speed of permeate flux by improving the backwashing efficiency of the separation membrane.;COPYRIGHT KIPO 2014;[Reference numerals] (AA) Decompression pump
