Abstract
A method for filtering liquid includes directing the feed liquid into an annular space between concentrically arranged filter sleeves formed of flexible bag filter type filtration media. The liquid enters the annular space via openings formed in an inlet plate attached to the sleeves. The central area of the inlet plate is closed to prevent flow of unfiltered liquid into the cylindrical space defined by the innermost filter sleeve, whereby all liquid entering the filter assembly is filtered by the sleeves.
