Smaller-footprint BWT released by Alfa Laval


Alfa Laval have announced a new ballast water treatment system, the PureBallast 3.1 Compact Flex, with a smaller footprint and reduced installation costs.

Based on loose components, the system is available for flows of 32–1000 m3/h, with a footprint up to 20% smaller than that of PureBallast 3.1. Alfa claim reduced installation costs of up to 10%, thanks to a plug-and-play concept for quick and easy connection.

“Alfa Laval PureBallast 3.1 Compact Flex is economical, both in its use of space and in its installation,” says Anders Lindmark, Head of Alfa Laval PureBallast. “As a result, it removes headaches for both ship owners and shipyards. It’s an ideal choice for the vast majority of vessels, combining the smallest possible footprint with superior performance in the widest range of conditions.

“Available now, Alfa Laval PureBallast 3.1 Compact Flex joins the existing PureBallast family of ballast water treatment systems adapted to different customer needs. PureBallast 3.1 handles high flows and special requirements, while PureBallast 3.1 Compact offers a skid-mounted option. These systems have U.S. Coast guard type approval, which is also pending for PureBallast 3.1 Compact Flex. All three PureBallast 3.1 systems provide the same superior performance in fresh, brackish and marine water, including full-flow operation in IMO-regulated waters where the UV transmittance is as low as 42%.”
