Abstract

Abstract Oil, solid particles such as biological slime and floating debris etc. are removed from water by an apparatus including endless chain means made up of a series of interconnected foraminous chambers holding a regenerable porous filter material such as polyurethane. Preferably the filter material has an outer large pore section and an inner small pore section. A plurality of buckets are attached to the chain means, and as the chain means moves through a closed loop path, these buckets catch debris and dump it into a holding bin. Simultaneously, the filter material absorbs surface and subsurface oil and the like from water traveling through the filter material. The filter material is regenerated by squeezing the filter material to release the oil.
