ABSTRACT:
An oil separation method and apparatus for separation by coarse particulation which includes the steps of forming a coarse particulating element with an oil water separation layer which includes forming a water insoluble hydrogel which has an oil resisting and oil repelling function as well as water permeating and absorbing function on the surface of a porous material and/or the surface of a fluid passage to be contacted with oil holding water and alternately passing the oil holding water through the surface of the element to perform coarse particulation separation of oil at the surface of the element. The oil water separation device corresponding thereto includes at least one coarse particulating element forming a layer which include a non-water soluble hydrogel layer with an oil water separation function and having both an oil resisting and oil repelling function as well as a water permeating and water absorbing function and a mechanism for passing oil holding water alternately from one side or the other of the element.
