The delivery of the first plant to China?s Jiangsu New Yangzi shipyard was set for March 2013.The CleanBallast technology gained official type approval from the Ger- man BSH in 2010, and was submitted for AMS and USCG approval in mid- 2012. At last year?s SMM exhibition, RWO officially launched a modified version of the system, based on the technology but using considerably less footprint. The treatment principle is based on two cleaning steps, consisting of the removal of sediments and bigger par- ticles by self-cleaning deep-filtration disc filters followed by a disinfection step using RWO?s patented EctoSys technology eliminating the remaining bacteria and organisms. Severn Trent De Nora: BalPure The IMO Type-Approved Balpure ballast water treatment system from Severn Trent De Nora has become one of the first ballast water treatment technologies to receive the United States Coast Guard?s (USCG) Al- ternate Management System (AMS) certification. The AMS certification has specifically approved the use of Balpure, which complies with IECEx Classification, in hazardous areas on board vessels. Severn Trent De Nora has sold and delivered 20 Balpure units since it received its IMO Type Approval in July 2011. ?The Balpure team has been working tirelessly to obtain the various approvals required for the system to be accepted for use on board international trading ves-sels,? said Marwan Nesicolaci, VP, global sales and marketing, Severn Trent Services. ?This new AMS certification of Balpure is a significant milestone for us as it signifies the system is now permitted to be used on board ves-sels trading in U.S. waters that are required to comply with the USCG Final Rule. This achievement solidifies Bal-pure?s position as a robust and reli- able solution that shipping companies can trust.?As part of the USCG?s extensive re- view process for AMS, Severn Trent De Nora submitted: basic approval documentation, final approval docu-mentation, shipboard test data, Opera-tions & Maintenance manual, detailed drawings for each Balpure System (flow sheets, P&ID, general arrange-ment), and Bill of Materials (BoM) for each system including vendor technical literature and certification for all equipment. Balpure features proven electro-lytic disinfection technology, ease of installation and operation, minimal maintenance and low operating costs for both retrofits and newbuilds. Its slip stream treatment approach, where approximately one percent of the total ballast water flow is used to generate the hypochlorite disinfection solu-tion, enables remote mounting away from the main ballast line. The slip stream treatment approach, coupled with a design that requires treatment only during the uptake of the ballast-ing cycle, offers significantly reduced power requirements when compared to competing technologies ? ensuring low operational costs. Balpure offers a virtually maintenance-free approach to ballast water treatment through the use of proprietary self-cleaning electrodes that eliminate the need for time-consuming chemical and me-chanical maintenanceSevern Trent De Nora: BalPure MR #5 (26-33).indd 31MR #5 (26-33).indd 315/2/2013 12:34:00 PM5/2/2013 12:34:00 PM
