Apparatus for the treatment of liquids contaminated by foreign substances
First Claim
1. An apparatus for the treatment of liquids including foreign substances, comprising a membrane separating structure having opposite axial ends and including a membrane support element and membrane elements mounted in said membrane support element, said membrane separating structure having an inlet at one axial end for receiving the liquid to be separated and passing it past said membrane elements whereby a permeant portion of said liquid permeates through the membranes of said membrane elements and a retent portion of said liquid is enriched with said foreign substances, an outlet for discharging said permeant portion, and another outlet at the opposite axial end for discharging said retent portion, said membrane elements being arranged so as to form together at least one flow channel extending longitudinally through said apparatus and said membrane support element having flow openings in alignment with said at least one flow channel and adapted to guide said liquid to be treated and said retent portion in a straight line through said flow openings and said flow channel past the membrane elements forming said flow channel and out of said apparatus, repectively.

Abstract
In an apparatus for the treatment of liquids including foreign substances, particularly municipal and commercial waste waters, comprising a membrane separating structure having membrane elements, an inlet for receiving the liquid to be separated and passing it past the membrane elements whereby a permeant portion of the liquid permeates through the membranes and a retent portion becomes enriched with the foreign substances, and outlets for discharging the permeant portion and the retent portion, the membrane elements are arranged so as to form together flow channels extending longitudinally through the apparatus and adapted to guide the liquid straight through the flow channels along the membrane elements.
