Can the seawater with its contents of S be pumped straight overboard, after it is clarified for soot?
Once the wastewater has been cleared of soot and hydrocarbons, it is a solution having higher than ambient sulfate, but this is a naturally occurring component, and not considered an ocean pollution hazard. Before overboard discharge, the water must be passed through the ship’s existing bilgewater treatment system, or a stand-alone system supplied by MES to remove any residual hydrocarbons.
