Answers for your tanker’s needs

A wide range of system advantages and dedicated technical solutions make PureBallast 3 the ideal choice for ballast water treatment on tankers.

Handling large ballast flows

Your tanker may require hundreds of thousands of tons of ballast water – which means large ballast water flows. PureBallast 3 handles even very large flows with a small footprint and low power consumption, thanks in part to a 1500 m3/h reactor size. Single systems can handle up to 3000 m3/h, while dual systems can be used for coverage up to 6000 m3/h.
