ABSTRACT:
A process for reducing the pollutant concentration of effluent liquor from wool-scouring operations. The suint concentration of scouring liquor is allowed to build up to a point where suspended dirt and grease particles are destabilized and hence more efficiently removed by centrifugation. The centrifuged liquor is then recycled for further wool-scouring. Apparatus is also provided.
