Bilge water deoilers are systems on board seagoing vessels that treat the bilge water in accordance with the legal requirements. The bilge water is treated to such an extent that it can be separated into clear water and oil sludge. The clear water can then be returned to the sea. The oil sludge, on the other hand, is either burned with the heavy oil in the engine or disposed of on land as hazardous waste. Our valves control the draining of the oil during this process.
