Alfa Laval reports a growing customer interest in high flow capacity PureBallast ballast water treatment systems (BWTS).

Alfa Laval is ready to support vessels with these needs. The IMO and U.S. Coast Guard (USCG) type-approved PureBallast 3.1 features a single-filter solution that enables it to deliver higher capacities – up to 6,000 cu m/h – with a small footprint.

Alfa Laval has recently signed a deal to supply two LNG carriers, Korean shipyard newbuilds, with installations comprised of two parallel 3,000 cu.m/h systems.

"Traditionally, many have operated under the assumption that high flows require chemical treatment systems," notes Kristina Effler, Global Business Manager for Alfa Laval PureBallast. "But today, more shipowners and operators are seeing the benefits of PureBallast's enhanced UV disinfection technology, which can handle a much broader range of flows than other UV systems."

The benefits include reduced installation costs and a lower operating cost, meaning substantial savings over the vessel;s life cycle.

"The high interest in Alfa Laval PureBallast provides clear evidence of growth in the retrofit market, and there are many reasons this is happening right now," says Anders Lindmark, Head of Alfa Laval PureBallast, Alfa Laval Marine Division. "We have received lots of interest directly tied to our recent USCG type approval, and we're also seeing greater numbers of ship owners preparing for the IMO convention."

For ship owners who put off selecting a ballast water treatment system during the lengthy ratification process for the BWM Convention, the global requirements taking effect in September leave little time to make a decision.

"Alfa Laval is well prepared to guide customers who are only now entering the market," says Lindmark. "We've developed a wealth of knowledge in more than a decade of experience with ballast water treatment, and we're providing resources to help ship owners understand their options."
