ABSTRACT:
An oil collection system comprising a two-part housing defining an interior cavity and an annular opening in the side thereof to permit flow of oil into the cavity, a pleated or variable pore size hydrophobic-oleophilic screen mounted in the opening to permit passage of oil but not of water therethrough, an outlet passage extending from the bottom of the cavity through the housing and adapted for connection to an outlet hose and pump, a pump controller mounted within the housing and including a float having a magnet in the bottom thereof and a soft magnetic element in the cavity bottom adjacent the float, and a chlorinator for preventing biological growth on the screen. A draw bolt holding the base and cover together, about the annular screen, also forms a guide shaft for the pump-actuating control float. As the pump controller requires the unit to fill before activating the pump a progressive sinking of the unit occurs during a pumping cycle, a movement which is enhanced by the limitation to buoyancy provided by the block-form floats shown. The oil collection capability of this unit in the presence of thin oil films in enhanced by this accentuated sinking movement.
