Abstract
A process is provided for the ultrafiltration of stabilized emulsions, such as cutting oils, which comprises circulating the emulsion through a chamber partially bounded by a porous membrane, and before the emulsion enters the said chamber, a small quantity of salt is introduced into it, corresponding to a weight ratio of salt/oil present in the emulsion between 0.01 and 0.2.
