Abstract
Precoat treatment of polysulphone membranes with non-ionic surfactant BRIJ 58 was effective in decreasing antifoam fouling in ultrafiltratio n 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.
