A flexible diffuser membrane is provided with a unique system of perforations arranged to result in uniform distribution of gas even though the membrane deflects to different extents or the submergence varies in different parts of the membrane. The perforations are arranged to provide less perforation area per unit of perforated membrane surface area in the membrane parts that deflect the most or are submerged least and greater perforation area in membrane parts that deflect the least or are submerged most. The perforations can be slits arranged in parallel rows on a tubular membrane, in concentric circles or another pattern on a disk membrane, or in still a different pattern on a flat panel diffuser membrane. The slit length or separation can be varied between different zones on the membrane surface or the spacing between rows or circles can be varied.

The filter core is composed of connection pipe coupling sleeves, a mounting handle, a membrane part, and a fixing end plate. When filtration is operated, under the suction effect of a vacuum pump, part of the liquid in unfiltered liquid penetrates membrane-surface micro-pores and enters the inner cavity of hollow fiber membranes, such that a clear filtrate is produced; cross-flow liquid in a cross-flow pipe enters a central pipe through a cross-flow interface, and is injected to the surfaces of fiber membrane bundles through radial nozzle holes; the hollow fiber membranes are abraded with each other; under the cooperation of water current impaction, suspended matters adhered to the membrane surfaces are brought away. With the cross-flow submerged membrane filter core, high cross-flow speed is not needed. The distance between the radial nozzle holes and the fiber membrane bundle surfaces is short, operation with low cross-flow speed is maintained, and energy consumption is low. Cross-flow filtering and cross-flow washing can be carried out alternately.
