<p>A filtering method and system using a flexible filter that can prevent adhesion of an outlet side housing with a filter element, ensures an excellent flow of liquid, and exhibits excellent filter performance is provided. <??>The filtering method and system are characterized by maintaining the pressure at the outlet side of a filter at 0 mmHg or more above atmospheric pressure, when filtering the liquid by gravity or by using a feed pump through a filter comprising a flexible housing having an inlet port and outlet port for the liquid and a sheet-like filter element, the inlet port being separated from the outlet port by the filter element. <??>Provided also are a filtering method and system that can maintain the pressure at the outlet side of the filter at 0 mmHg or more above atmospheric pressure by appropriately selecting the combination of hydrodynamic characteristics of the filter and the flow channel on the upstream and downstream sides of the filter. <IMAGE></p> |
