<p>Evoqua Water Technologies' electrochlorination based solution, called SeaCURE Ballast Water Management System (BWMS), has completed biological efficacy US Coast Guard Type Approval tests.</p><p>The tests were conducted under the supervision of classification society Lloyd’s Register.</p><p>An independent laboratory, NSF International will now gather test data, which will be submitted to the USCG for approval.</p><p>Ballast Water business manager Matt Granitto said: “We are delighted that the SeaCURE system has successfully completed and exceeded all testing requirements and protocols for USCG certification. It has been a lengthy process but the importance of these tests and USCG Type Approval cannot be undervalued.</p><p>“The testing regime we opted for was the most stringent because it uses natural organisms in natural environments over those that are manufactured. By using real organisms, it takes a lot longer as nature doesn’t always have sufficiently high organism counts.”</p><p>NSF International carried out all the testing. The first five tests were done in brackish waters of Baltimore harbour in 2015 by NSF partner Maritime Environmental Resource Centre (MERC).</p><p>Great Ships Initiative (GSI), another partner laboratory, undertook five freshwater tests in 2016. The last set of land based tests was completed by Holland’s MEA-NL along with classification society Lloyd’s Register in July this year.</p><p>Shipboard testing was carried out in several locations across the world.</p><p>NSF International was the first independent laboratory to be certified by the USCG for BWMS testing.</p><p>Evoqua’s global vice president for electrochlorination Ian Stentiford said: “We deliberately selected an independent laboratory that would challenge the SeaCURE system as part of the whole approval process.</p><p>"The testing NSF partners carry out is extensive and places considerable demands on the system in real-life, operational conditions. Testing uses real organisms, in different salinities, different water temperatures and different local environments, taking into account organism regrowth.</p><p>“It is very stringent; but we knew that if the SeaCURE system could pass these tests, then shipowners will be confident that the system they have invested in is very robust and it can actually do what it has been designed for in all at-sea operating conditions encountered.”</p><p>The SeaCURE system is claimed to be one of the smallest electrochlorination-based ballast water treatment systems to have completed USCG testing.</p>Evoqua expects to secure USCG BWMS Type Approval before the end of this year.
