A 100 GPM filtercoalescer 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 milligramsliter MGL. Bilge mixtures were processed both at sea and in port. Normal water effluent oil concentrations were 12 to MGL. Ballast mixtures were processed in port. A maximum of 5 MGL 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
