Viewpoint planning: the visibility constraint

Apparatus for separating floating pollutants from a body of water. A vessel has an opening in at least one side to define an inlet for the pollutant and the top water layer. There are means within the vessel to impart a whirlpool motion to the admitted pollutant and water in which the pollutant forms a thickened upper layer. A nozzle is positioned at about the center of the means to impart whirlpool motion. The nozzle projects upwardly. A separator is positioned beneath the nozzle whereby floating pollutants can be removed from the top of the separator and water from the bottom of the separator.
