Abstract

Abstract A method and apparatus for removing organic contaminants from an aqueous phase in which the contaminant is solubilized. In the method the aqueous phase is passed through a fluid-pervious filtration media which has been infused with an absorbtion composition comprising a homogeneous thermal reaction product of an oil component selected from the group consisting of glycerides, fatty acids, alkenes, and alkynes, and a methacrylate or acrylate polymer component. The contaminant is thereby immobilized at said media, and the purified filtrate having passed through the filtration media is collected as the product.

Claims Analysis

Total Claims: 23
Claim 1
Independent Claim 91 words
A method for removing organic contaminants from an aqueous phase in which the contaminant is contained, comprising: passing said aqueous phase through a fluid-pervious filtration media which has been infused with an absorption composition cured in situ at the infused media, said composition comprising a homogeneous thermal reaction product of an oil component selected from the group consisting of glycerides, fatty acids, alkenes, and alkynes, and a methacrylate or acrylate polymer component; said contaminant being thereby immobilized at said media; and collecting the purified filtrate having passed through said filtration media.
Claim 2
Independent Claim 91 words
A method for removing organic contaminants from an aqueous phase in which the contaminant is contained, comprising: passing said aqueous phase through a fluid-pervious filtration media which has been infused with an absorption composition cured in situ at the infused media, said composition comprising a homogeneous thermal reaction product of an oil component selected from the group consisting of glycerides, fatty acids, alkenes, and alkynes, and a methacrylate or acrylate polymer component; said contaminant being thereby immobilized at said media; and collecting the purified filtrate having passed through said filtration media.
