Abstract

Precoat treatment of polysulphone membranes with non-ionic surfactant BRIJ 58 was effective in decreasing antifoam fouling in ultrafiltration of five model process streams such as fermentation media, broth and yeast suspension. The mean flux increase of about 90 % was achieved by the surfactant pretreatment.
