An investigation was made to develop a 'package' type unit suitable for shipboard separation of ballast water from Bunker 'C' fuel oil. A 'State of the Art' survey showed that existing commercial methods of separation depended upon specific gravity differences or required equipment unadaptable to shipboard use. A means of separation was developed which involved the use of a capacitance probe 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 ballast water containing less than one percent oil would be passed through a series of Dutch weave coalescing screens. This treatment would reduce the oil concentration to 100-200 parts per million, further reduction being accomplished by means of a replaceable fibre glass cartridge. The practical operation of such a system would be demonstrated by a full-scale land-based experimental installation.(Author)
