Using the same approved electrochlorination technology, Evoqua Water Technologies has remodelled its SeaCURE ballast water management system to provide optimum high flow rate performance from what is now one of the smallest electrochlorination systems on the market.
Introduced during the Nor-Shipping 2017 exhibition and conference, in Lillestrøm, Norway, the next generation SeaCURE System is a skid-mounted, plug-in-and-play ballast water treatment system that is 76 per cent smaller and 85 per cent lighter than earlier generations of the system.
Speaking at the introduction, Matt Granitto, business manager for Evoqua’s ballast water business, said: “Without reducing the high flow rate capacity of the existing SeaCURE system, we have dramatically reduced the number of components to create a modular system mounted on a 2m x 1.5m, easy to install skid. It is one the of smallest ballast water management solutions available capable of treating flow rates of up to 6,000m3/h. I don’t think anyone can treat the flowrates in the space we can.”
With installation and operational simplicity a key factor behind the updated design, the next generation SeaCURE system can fit through standard hatchways and can be installed by riding crews, reducing substantially pre-installation work and time required during drydock.
Ian Stentiford, Evoqua Water Technologies’ global vice-president, electrocatalytic business, said: “The development of our core electrochlorination technology, which can now generate up to six times more output from the electrolyser is the main driver behind the remodelled SeaCURE system. The advancement has enabled our manufacturing and design partners to standardise the system, developing multiple dose lines capable of treating three ballast lines from a single skid, as well providing marine growth prevention for up to four sea chests. What they have created is a universal enclosure that can be assembled rather than fabricated. Not only is the re-modelled system simple to install, we have been able streamline and reduce the maintenance requirement.”
A key feature, and one that is likely to prove a commercial lure to shipowners, is the dual functionality of the system. Based on the company’s 50-year experience developing electrochlorination technologies, a SeaCURE BWMS can be configured to also work as a vessel’s marine growth prevention system, protecting against the build-up of biofouling in seawater in critical machinery and cooling systems.
