Abstract: An apparatus for and method of filtering hydrocarbon contaminated water, which is used in a system requiring a pump to lift low lying hydrocarbon contaminated liquids from said pump through a filtration system which lifts and completely filters all debris and hydrocarbons from said liquid.

Abstract: An apparatus for and method of filtering hydrocarbon contaminated water, which may be used in drainage openings in parking lots and containment areas for large sources of hydrocarbons to remove hydrocarbons from hydrocarbon contaminated water. The apparatus has a filtration compartment which filters out debris which may clog the treatment compartment. A pre-filtration and means for melting snow may be incorporated. The treatment compartment contains a hydrocarbon absorption media which absorbs any hydrocarbons present in the water rendering such water substantially hydrocarbon-free for discharge directly into a stream or groundwater. If a hydrocarbon spill occurs, the hydrocarbon absorption media forms a plug which seals off the flow of contaminated water. A hydrocarbon solubilizing material capable of effectively removing sheen in a first pass may be disposed as a top layer over the hydrocarbon absorption media.

Abstract: An apparatus for and method of filtering hydrocarbon contaminated water is disclosed herein. The present invention may be used in drainage openings, particularly in parking lots and containment areas for large sources of hydrocarbons such as oil tanks or electrical transformers, to remove hydrocarbons from hydrocarbon contaminated water. The apparatus has a filtration compartment which filters out debris and sediment which may clog the treatment compartment. A pre-filter attachable to the apparatus may be used to further aid in filtering out sediment. A means for melting snow and ice may be incorporated within the filtration compartment such that liquid flow is not hindered during extreme weather conditions. The treatment compartment contains a hydrocarbon absorption media which absorbs any hydrocarbons present in the water rendering such water substantially hydrocarbon-free for discharge directly into a stream or groundwater.
