Abstract: Apparatus and process for the concentration of a liquid containing non-ultrafiltrable elements, e.g. ascitic fluid in which liquid is fed to an ultrafilter having a membrane therein, and the concentrate and ultrafiltrate are withdrawn from the ultrafilter in which a pressure drop is induced in the concentrate by an auxiliary hydraulic resistance causing a pressure drop in concentrate which is proportional to the pressure drop exerted on the ultrafiltrate by the membrane in the inverse ratio to the ratio of the flow rates of the concentrate and of the ultrafiltrate.

Abstract: A device for purging gas bubbles from a liquid in which a wall is arranged to form a passageway, at least half of the wall being in the form of a hydrophobic porous membrane having a pore size between 0.01 to 30 mu . The liquid flows parallel to the membrane in a passageway between 0.5 and 10 mm maximum thickness and the gas escapes through the pores. The membrane may be formed into a tube and may act as a connector between two lengths of piping, the gas escaping between the ends of the piping. In another construction the device is in the form of a sachet having an intermediate impermeable wall, the liquid being caused to flow parallel to the sides of the wall of the sachet.
