ABSTRACT:
An oil separation method and recovery device which may be towed or otherwise propelled over, or left stationary on, the surface of a body of oil polluted water. If the unit is in motion, inverted V-shaped troughs intersect the liquid surface causing the oil polluted water to flow into an inner chamber as the oil rises to the trough vertices. If stationary, high pressure water is used to force the oil polluted water along the troughs to the inner chamber as a vacuum is created. In either case, but particularly the latter, the contaminated water flow path is improved by utilizing depolluted discharging water to induce a surface current of the oil polluted water to flow toward the troughs. Also, the utilization of a heating means keeps the oil flowing expeditiously through the troughs.
