Abstract:
1. For use in a filtration system for removing oily contaminants from an aqueous medium, said system including at least a first filtration stage for removing said oily contaminants; a visual effluent water quality indicator for examining and evaluating the quality of treated effluent flowing at the output line of said first filtration stage, comprising: a filtration status chamber inserted in said output line, said chamber having a transparent outer wall to enable viewing of the interior of the chamber; said chamber including a filtration media adapted to absorb said oily contaminants, said filtration media comprising a fluid-pervious media which has been infused with an absorption 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 being thereby immobilized at the said filtration media; and said filtration status chamber having means for channeling the flow received therein in a direction proceeding from the chamber lateral walls toward its central axis, whereby any of said oily contaminants in the flow collects selectively at the outer portions of the filtration media which are highly visible to an operator of the system.
