apparatus for the treatment of serosa effusions by concentration and aterinjicering of set aside vetska

摘要

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fluid in which liquid is fed to an ultrafilter having a membrane therein, and the concentrate and ultrafiltrate are withdrawn from the ultrafilter in which a pressure drop is induced in the concentrate by an auxiliary hydraulic resistance causing a pressure drop in concentrate which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.
