RESEARCH AND DEVELOPMENT FOR A SHIPBOARD OIL AND WATER SEPARATION SYSTEM. PART 1. BACKGROUND AND INITIAL INVESTIGATIONS. PART 2. FIELD TESTING OF LAND-BASED UNIT AND DESIGN OF SHIPBOARD PROTOTYPE

A step-by-step program was carried out under Part 1 of this investigation to obtain information on which to base the development of a practical package type unit suitable for shipboard separation of ballast water from Bunker 'C' fuel oil. A 'State of the Art' survey showed that existing commerical methods of separation depended solely upon specific gravity differences or required other equipment equally unadaptable to shipboard use. Based on this study, the most feasible means of separation of oil from ship deballast water was to use a developed capacitance probe as a signal to divert the relatively small amount of ballast water containing over one percent oil to a holding tank or existing ballast tank. The remainder of the oily ballast water containing less than one percent oil could be effectively treated by passing the oil-bearing waters through a series of Dutch weave screens where coalescence effected the oil-water separation. The practical operation of such a system would be demonstrated by a full-scale land-based experimental installation under Part 2 of this investigation.
