A Siemens subsidiary has obtained a patent from the U.S. Patent and Trademark Office for a technology designed to reduce biofoul growth in ballast water treatment filters.
Siemens Water Technologies built the technology to work with the SeaCURE ballast water management system and minimize marine organism buildup in the filters by injecting biocide into ballast seawater, Siemens said Tuesday.
Lukas Loeffler, Siemens Water Technologies CEO, said the patent is part of the subsidiary’s goal of continuing to develop new technologies.
The SeaCURE system is designed to separate organisms through a 40-micron weave-wire screen and operate at high sediment loads while preventing backwash flow, Siemens says.
SeaCure is also built to treat cooling water circuits and comply with the International Maritime Organization Convention’s D-2 regulations.
The technology received final approval from the IMO in 2012.
