MEMBRANE FILTERING DEVICE WITHOUT TREATED WATER STORAGE AND MEMBRANE WASHING METHOD THEREOF

摘要

The present invention relates to a membrane filtering device without treated water storage, which includes a plurality of filtering pumps for supplying supply water, a separation membrane filter for filtering the supply water by a separation membrane, a filtered water valve for regulating the discharge of filtered water, a backwashing valve for regulating the backwashing of the filtered water, a backwashing pump for distributing the backwashing water to a separation membrane filter, and a back washing water valve regulating the supply of the backwashing water. Accordingly, the present invention prevents recontamination of a separation membrane due to backwashing by improving space efficiency of the membrane filtering device and preventing contamination caused by remaining filtered water, and improves energy efficiency by reducing driving energy of an after treatment process.
