Patent ID: 7264721

Claim:
A filtration apparatus for separating organic contaminants from an aqueous phase in which the contaminant is solubilized or emulsified, comprising: a canister having an inlet and an outlet for passing said aqueous phase therethrough; a fluid-pervious media being provided at the interior of said canister in the flow path of the aqueous phase proceeding between said inlet and outlet, said media being infused with an absorbent composition comprising a homogeneous thermal reaction product of an oil component selected from the group consisting of glycerides, fatty acids, alkenes, and alkynes, with a methacrylate or acrylate polymer component; said absorbent composition being cured in situ at the media by the infused media being subsequently exposed to actinic UV radiation; said contaminants in the aqueous phase flowing through said canister thereby coming into intimate contact with and being immobilized at said media; and said media comprising a central core which is surrounded and wrapped by a plurality of overlying sheets of further fluid pervious media and the actinic UV radiation penetrating to said core resulting in differential tackiness through the sheets, the overlying sheets creating void spaces between sheets for trapping of at least some of the separated contaminants.
