CROSS-FLOW FILTRATION SYSTEM USING MICRO OR NANO-SIZED BUBBLE
摘要
PURPOSE: A binary backwashing system using micro nano bubbles is provided to shorten time required for a cleaning process and clean foreign materials from a filter by uniformly distributing air nano bubbles in the pores of the filter. CONSTITUTION: A washing water pipe(20) supplies nano bubble water containing nano bubbles to a filter. A nano bubble water generating module supplies the nano bubble water to the washing water pipe. A washed water discharging pipe(21) discharges washed water generated after a filter washing process. A venturi injector dissolves air from an air compressor in washing water. A first valve is arranged in the combination region of a raw water pipe and the washed water discharging pipe in order to connect the filter with either of the raw water pipe or the washed water discharging pipe. A second valve is arranged in the combination region of a purified water pipe and a washed water pipe to connect the filter with either of the purified water pipe or the washed water pipe.
