Swedish engineering group Alfa Laval has unveiled a new UV reactor size for its PureBallast 3 family at this year’s SMM fair.
The company says that the 1500 m3/h version is optimized for 50% more flow than the current largest reactor size, enabling streamlined and cost-effective configurations for tankers and other vessels with large ballast water flows of 1000 m3/h or more.
“Alone or in combination, the reactors enable PureBallast 3 system flows of 32–3000 m3/h, with multiple systems handling even larger capacities. A 3000 m3/h system will be achieved with just two reactors, for example, while a 1500 m3/h system will go from two reactors to one,” the company explained.
Having fewer reactors on board enables owners to cut their operating costs and reduce the complexity of installing a large-flow ballast water treatment system.
“Many ship owners are reconsidering what they’ve been told about ballast water treatment for large flows,” says Anders Lindmark, Head of Alfa Laval PureBallast.
“Heating needs, tanks for high-salinity water and the management of chemicals add size, complexity and cost for electrochlorination systems. PureBallast 3 is already highly competitive for large flows – and will be even more so with the 1500 m3/h reactor.”
“When it comes to ballast water treatment for large flows, the 1500 m3/h reactor doesn’t just strengthen our offering. It truly changes the equation for UV.”
The new reactor joins an existing PureBallast 3 range that comprises 170, 300, 600 and 1000 m3/h reactor sizes.
