ABSTRACT:
This disclosure is directed to a membrane filtration installation having a liquid inlet chamber and a liquid outlet chamber, each of which was a pipe plate and a number of support pipes between the pipe plates. The inner side of the support pipes structurally support a non-woven tube having an inner tubular membrane on its inner side. At each end the membranes with non-woven tubes are accommodated in openings in the pipe plates. Each membrane engages a sealing sleeve which is integral with a flange which cooperates with the pipe plate beside the openings. The flange is provided with a circumferential annular shoulder which clamps and sealingly engages the pipe plate and the lower edge of the wall of a liquid outlet or inlet chamber by means of a nut engaging a shoulder on the liquid chamber and which is screwed on the outer side of a pipe plate. Preferably the flange is provided with an annular rounded shoulder for engaging the lower edge of the liquid inlet or outlet chamber.
