Abstract

PURPOSE: To selectively permeation separate oil-free water or oil-immiscible solvent on a mass scale by treating a treating liquid of a specific compsn. contg. a surfactant and oil with a porous membrane made of resin the critical surface tension of which is above a specific value.
CONSTITUTION: A porous membrane with an average pore diameter of 0.005W 5 μm is made of resin with a critical surface tension on pore surfaces above 35, esp. above 40 dyn/cm or of resin mixt. The resin includes PVA, PVC, etc. On the other hand, an emulsion is provided at least contg. oil, a liquid such as water or solvent to be removed and a surfactant, and having a compsn. represented by the equation. This emulsion is then allowed to permeate through the porous membrane at 35W90, esp. 40W70°C to separate oil-free water or oil-immiscible solvent.
