BWMS · Ballast Water Treatment
PPT-BWS/MESB 5000 is a ballast water management system (BWMS) from MAHLE NFV GmbH, listed in DNV approval records. It treats ballast water during uptake and discharge so the vessel can meet the discharge standard of the IMO Ballast Water Management Convention, and it is normally installed in the pump room or engine room in series with the ballast pumps. The designation identifies the specific size or variant; operating limits, treatment details and commissioning requirements must be taken from the type approval certificate and the manufacturer's manual.

What our service work and the manufacturer documentation say about keeping this model running.
Check filter condition, backflush operation, sensors, valves and control-system alarms against the type approval certificate and the Ballast Water Management Plan. A class surveyor typically reviews the approval documents, operation and maintenance records, instrument calibration records and the ballast water record book. Follow the manufacturer's manual for intervals and consumables.
Keep spare filter elements or screen parts, seals and gaskets, calibratable sensors, fuses and control cards, and the valve and actuator wear parts named in the manufacturer's spare-parts recommendation. Hold treatment-stage consumables as specified in the approved manual.
