TEST AND EVALUATION OF OIL POLLUTION ABATEMENT DEVICES FOR SHIPBOARD USE, PHASE III

A 100 GPM filter/coalescer oily water separator system designed for both bilge and ballast service was installed on a 210 ft. Medium Endurance U. S. Coast Guard cutter. The separator water effluent was monitored by an on-line infra-red absorption type monitor. The alarm points were set to recirculate water effluents exceeding 20 milligrams/liter (MG/L). Bilge mixtures were processed both at sea and in port. Normal water effluent oil concentrations were 12 to MG/L. Ballast mixtures were processed in port. A maximum of 5 MG/L was discharged overboard during this procedure. A soap-like substance was accidentally processed while in port. The mixture could not be adequately separated to permit discharge overboard. All other emulsions were separated satisfactorily. (Modified author abstract)
