Alfa Laval ups the standards
Swedish shipboard water treatment supplier Alfa Laval has recently announced that its bilge water system, PureBilge, can now achieve 5ppm filtration and has also been certified at this level by DNV.
T
he DNV Clean Design class notation is a voluntary newbuilding specification, which
covers most aspects of ship design and operation. For bilge water, Clean Design stipulates a maximum of 5ppm of oil remaining in the water aſter treatment, prior to pumping overboard. MARPOL regulations stipulate 15ppm. In 2011, DNV introduced a 5ppm type approval process for marine bilge water separators. Alfa Laval’s PureBilge is claimed to be
the first system to obtain the new 5ppm DNV type approval certificate. Te system has also been granted the US Coast Guard Certificate of Approval. In May 2011, the DNV 5ppm Type Approval Programme
No. 771.60 became available for
certification for Oily Water Separators (OWS) for the first time. Alfa Laval’s PureBilge system was
tested according to this procedure and in December 2011 Alfa Laval obtained Type Approval Certificate No. P-13965 for PureBilge 2005 and 5005 (2.5m3/h and 5.0m3/h). The
development of the 5ppm Alfa Laval’s PureBilge achieves 5ppm.
approval has been driven by cargo owners and their customers, say Alfa Laval. It also claims that since its release on the market in June 2009, PureBilge had been tested onboard ships under real life conditions and consistently achieved results below 5ppm. NA
