ABSTRACT:
Method of treating wool scouring liquor effluent to render it suitable for recycling or discharge and to concurrently recover wool grease as a by-product. The method comprises mixing scouring liquor effluent with sufficient alcohol to produce a concentration in excess of saturation to leave a discrete alcohol phase, adding a selected flocculant to effect a liquid/liquid separation of grease from the liquor and stripping the separated grease from the alcohol phase.
