Abstract
Abstract Floating apparatus to be anchored across a polluted stream to skim the water and collect the debris. The apparatus includes a floating boom anchored within abutments by means which also provide barrier seals. The upstream side of the boom presents a baffle surface. Adjacent the baffle surface a series of paddle means skim the water and collect the debris. At one end of the boom the paddle means traverse a ramp. The coaction of paddle means against the ramp moves skimmed liquids and collected debris to a sump.
