DEVELOPMENT OF A CENTRIFUGAL SYSTEM FOR SEPARATION OF OIL AND SOLIDS FROM SHIPBOARD DISCHARGE WATER

Initial design and laboratory testing of an oil-solids-water separating system is described. The system is intended to process ships' bilge water at a rate of 50 gpm and provide water effluent containing less than 15 ppm of oil. The primary components of the final design are: (1) a cleanable bag strainer to retain coarse and fibrous solids, (2) a centrifugal pump that also separates settleable solids, (3) a coalescing centrifuge that separates well-dispersed oil, and (4) an oil-water monitor that continuously measures and records the oil-in-water concentration of the effluent. Results of component testing indicates that the overall system is capable of processing 50 gpm of bilge water containing concentration up to 10 percent No. 2 fuel or lube oil and discharging water effluent with 15 ppm or less of oil. The following elements of this system design are described in detail: (1) the test evaluation of the Fram-Akers primary separator: (2) the development and testing of the FMA Solids-Oil-Separating Pump; (3) the evaluation of the laboratory model FMA Centrifugal Coalescer; (4) the development and testing of the FMA Shipboard Centrifugal Coalescer; and (5) the synthesis of the Shipboard Separator System.
