ABSTRACT:
An oil absorption filter for extracting free oil from the used wash water of a laundry has platforms which extend in parallel and laterally across a tank, but do not reach across the total length of the tank so as to provide an avenue of fluid flow between the platforms.. Multiple entrances are provided into the tank to resulting in a slow flow of used wash water into the tank so as to encourage free oil to separate from the used wash water. Hydrophobic socks are vertically arranged in rows and placed through holes in the platforms. A partitioned pumping chamber is provided with an entrance proximate to the bottom of the tank which is the only avenue of entry for oil-filtered water to access the pumping chamber. A sump pump connected electrically connected to a level float pumps the oil filtered water out of the pumping chamber and out of the oil filter.
