Abstract

An apparatus for a high pressure ultra-filtration of a permeate or filtrate from a crude solution characterized by a module having an inlet for the crude solution, an outlet for the crude solution, a pressure stable capillary diaphragm as the main filtration element, means holding the diaphragm in said module, the filtration element being of a structure most favorable to the flow techniques in which the capillary diaphragms are permeated from the outside toward the inside as the crude solution flows in the axial direction therealong under a flow pressure gradient, an outlet for the permeate passing into the capillary diaphragms and means for creating a flow pressure gradient on crude material being supplied to the module. Preferably, capillary diaphragms are porous glass capillaries which are secured at one end with the other end being closed and free to adjust its position in the module.
