ABSTRACT:
In a plate type membrane module in which a number of units, each comprising a membrane supporting plate with corrugated surfaces, and membranes formed on the corrugated surfaces, with permeate passageways between the membrane and the corrugated surfaces, are laminated in such a manner that passageways for a solution to be filtered are formed between the units. The waveforms of the confronted corrugated surfaces of adjacent membrane supporting plates are in same phase with each other. Thereby the pulsation of the solution and accordingly the vibration of the membranes can be effectively prevented, with the result that the membranes are prevented from early fatigue.
