New 1500 m3/h PureBallast 3 reactor for large flows

With a new UV reactor size of 1500 m3/h, Alfa Laval is increasing the installation flexibility of Alfa Laval PureBallast 3. The new reactor, which handles 50% more volume than the current largest reactor size, is good news for tankers and other vessels with large ballast water flows.

Optimal BWTS configurations for tankers and more

With the introduction of the 1500 m3/h reactor, PureBallast 3 systems will become even more optimized for large ballast water flows of 1000 m3/h or more. A 3000 m3/h system will be achieved with just two reactors, for example, while other system flows will go from two reactors to one.

Having fewer reactors will further reduce the complexity and cost of installing a large-flow ballast water treatment system. This may strengthen a trend that can already be seen among tankers and other vessels with large ballast water flows, where electrochlorination is giving way to UV ballast water treatment.

The 1500 m3/h reactor will join an existing range of 170, 300, 600 and 1000 m3/h reactor sizes. Alone or in combination, the reactors enable system flows of 32–3000 m3/h, with multiple systems handling even larger capacities.

The confident choice

Alfa Laval PureBallast 3 is the leading ballast water treatment technology, providing unmatched biological disinfection performance in the most challenging waters
