SYSTEM FOR WASHING MEMBRANE, AND METHOD FOR WASHING MEMBRANE USING SAME |
摘要 |
A system for washing a membrane of the present invention comprises: a first membrane filtration tank which comprises a membrane and an aerator, filters inflow feed water by membrane filtration, and discharges treated water and water to be treated, respectively; a pressure gauge for measuring a differential pressure across the membrane and a flow meter for measuring a permeation flux which are provided at a produced water discharge line of the first membrane filtration tank; and a control means which calculates a recovery rate by calculating the water permeability from the differential pressure measured at the pressure gauge and the permeation flux measured at the flow meter, predicts a membrane contamination degree from the calculated recovery rate, and controls a backwash period and an intermittent aeration period. |
