Watercraft components Waste treatment technology Liquid-liquid separation Ocean pollution. Inlet to flotation stage The variety of oily wastes in bilge water can limit removal efficiency especially when very dense and highly viscous oils such as bunker oil are present. Separation and Purification Technology. A carefully managed environment is needed for the microorganisms which includes nutrients and hydrocarbons such as oil or other contaminates, and oxygen.
All Cargo vessels where MARPOL Convention bilge oil water separator applicable must have an oil record book where the chief engineer will record all oil or sludge transfers and discharges within the vessel.
