The development work of a new type, in-depth oil filter- coalescer for the treatment of oily ballast waters is described. Reticulated polyurethane foams emerged as the best filter-coalescer media affording bed fluxes in excess of 10 gpm/ft2 and simple regeneration via squeezing. Extensive separation tests in a 40 gpm unit with a variety of simulated oily ballast have demonstrated that an effluent of less than 30 ppm oil can be produced from an influent containing on the average of up to several thousand ppm oil including oil slugs. Substantial retention of suspended solids was also noted without causing either irreversible clogging of the foam or reduction in the oil separation efficiency.
