Abstract
The body-feed method, in which fine particles are admixed to the proteinaceous solutions to be filtered, is presented to form dynamic ultrafiltration membranes and compared with the conventional precoat method. It is shown that the ratio of the body-feed to solute concentrations is an important factor to maintain the high solute rejection, and that there exists an optimum filtration pressure in view of both the solute rejection and the filtration rate.
