    Abstract: Oil and debris are removed from the surface of water using a revolving, partially submerged, endless brush belt. The brush belt has outwardly projecting bristles which ensnare the debris and pick up oil. Polypropylene bristles are preferred. The oil and debris are removed from the belt before the belt is reimmersed in the water. Alternatively, a brush-type drum could be used in place of the endless brush belt.

    Abstract: Oil-contaminated water is purified using apparatus having a revolving polyurethane foam belt which is mounted on an incline relative to the horizontal. The contaminated water moves past and through the revolving belt or the belt is mounted on a boat which moves the belt through the water. In either case, as the belt and water move relative to each other, the oil-contaminated water filters through the belt and is purified. The belt is then squeezed twice. First gently to remove water, and then vigorously to remove oil. The belt may include inner and outer abutting sections which are reinforced by a network of threads. The outer section which first contacts the contaminated water has a larger pore structure than the inner section.

    Abstract: 1,239,127. Removing oil from open water. STANDARD OIL CO. 24 Jan., 1969 [29 Jan., 1968], No. 4227/69. Heading B1D. [Also in Division F1] Oil is removed from open water by a layer of foam rubber or polyurethane 22 on drum 15, which rotates to move the layer under rollers 25, 30, so that first the surplus water, then the oil is squeezed out, the oil running from higher compression zone 30a on to roller 25 from which it is wiped by blade 36. The assembly is mounted on a barge or catamaran and thereby moved across the oil slick, drum 15 and the rollers being rotated by a motor. The layer 22 is immersed in the water so that hydrostatic forces assist the oleophilic and hydrophobic properties of the layer to force oil to adhere thereto.
