Method and apparatus for removing pernicious contaminants from bilgewater discharge

Abstract

A method and apparatus for removing contaminants from an oily bilgewater. In the method the bilgewater 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 contaminants are thereby immobilized at said media, and the purified bilgewater having passed through the filtration media is discharged, e.g. into a body of navigable water.
