Abstract:
1. For use in a bilge water filtration system which includes at least a first filtration stage having an input and an output line for removing oily contaminants; a visual bilge water quality indicator for examining and evaluating the quality of treated effluent flowing at the said output line of said first filtration stage, comprising: a bypass line connected to divert a test stream from said filtration stage output line and return the diverted flow back to the output line of the system; a filtration status chamber being inline in said bypass 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, the filtration media comprising 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 oily contaminants being thereby immobilized at the media; and said filtration status chamber having means for channeling the flow received therein in a direction from the chamber outer wall toward its central axis, whereby said oily contaminants in the flow collect selectively at the outermost portions of the filtration media which are highly visible to an operator of the system; and wherein the said bilge water filtration system includes at least a second filtration stage in series with said first stage, said second stage having an input and an output flow line; each filtration stage being provided with said filtration media; the said bypass line being connected between the said output line from said first stage and the flow output line from said downstream second stage; the said water quality indicator comprising a pair of said filtration chambers serially connected in the said bypass line, whereby the absence of oily contaminants in the downstream of said chambers indicates that there has not been a breakthrough of oily contaminants from the first to the second filtration stage and thus that the output flow from the filtration system is substantially free of said oily contaminants, or alternatively indicating by the presence of visually discernible oily contaminants at both said filtration chambers that there has been a breakthrough of the oily contaminants from said first filtration stage, requiring servicing thereof.
