Alfa Laval has developed standard deckhouse solutions for Alfa Laval PureBallast 3 Ex ballast water treatment systems. Each deckhouse is delivered as a pre-assembled solution, including the PureBallast 3 Ex system and all internal piping and wiring, for easy integration into the vessel. If needed (see below), a booster pump unit can be integrated to ensure sufficient pressure without modifications to the existing ballast pumping system.
