Abstract
A method of separating oleophilic-hydrophobic material from wash water is disclosed. The method includes the steps of mixing with the wash water, about 30-2100 ppm of a surfactant having the formula: ##STR1## where n is 6-20; and about 1-200 ppm of an enzyme chosen from among proteases, amylases, lipases, cellulases, pectinases and mixtures thereof. The mixture of wash water surfactant and/or enzyme is then permitted to stand for a time sufficient for the oleophilic-hydrophobic material to separate.
