Filtration membrane module

摘要

A filtration membrane module submerged with processed liquid in the processing tank. Plural plate-like, rigid membrane cartridges are vertically placed in parallel to each other as properly spaced from the adjoining membrane cartridges. The cleaning stream generating means for supplying a flow parallel to the membrane surfaces of the membrane cartridges opposes the gaps between the membrane cartridges opposite to each other. The sucking means for sucking the permeated liquid in each membrane cartridge is communicated with each passage of permeated liquid in each membrane cartridge. The membrane supporting plate for retaining the filtration membrane of the membrane cartridge is made hollow using a rigid structure member.
