Method of filtering using a double-density commercial filtering system |
摘要 |
Filtering systems used to filter contaminated fluid. The filtering system (10) includes a supply pump (12); a filter tank (14) having a plurality of removable filter cassettes (16) disposed therein, each filter cassette housing in proper orientation a filter pad (164); a suction pump (18); a level control mechanism (148) maintaining a substantially uniform level of contaminated fluid within the filter tank; and a control panel (20) housing other process control components. Operation of the filtering system includes a backflush cycle and a relaxation cycle to extend the loading life of the filter pads. Also included is a preventive measure designed to eliminate fluid shear that may result as the filter pads approach the end of their loading life. The double-density filtering system (300) employs double-density filter cassettes (304), each cassette housing a pair of filter pads (164). This allows the volume of the filter tank (302) to be reduced, thereby reducing turnover. An enlarged chamber (392) within the double-density filter cassettes reduces fluid turbidity, thereby increasing both flow performance and filter pad loading life.
