BWMS · Ballast Water Treatment
The MAHLE NFV GmbH PPT-BWS 500 is a ballast water management system (BWMS) listed for installation in the ballast water treatment arrangement of a ship. It treats ballast water during uptake and discharge so that the discharged water meets the applicable ballast water management convention discharge standard. The system sits in the ballast piping, normally in the machinery space or pump room, with controls linked to the ballast pumps and valves. Flow capacity, installation arrangement and operating limits are set by the approval and the manufacturer documentation for the exact model.
