Abstract

A membrane filter has a pressure tight housing. It contains a number of separate disc shaped membrane support elements. It has an inlet for feed and outlets for concentrate and permeate. At least one baffle to guide the flow is installed between each pair of supports. Used for reverse osmosis or ultrafiltration. The liq. to made to flow over the whole surface of the membrane without using discs of different dia. and shape to guide the flow.
