Evoqua Water Technologies’ type-approved SeaCURE Ballast Water Management System can help shipping companies meet international ballast water requirements without additional chemicals, the company says.
The SeaCURE system utilizes a patented process that first injects biocide into ballast seawater before it reaches the large surface filter intakes to reduce the growth of marine organisms that can clog the filters. Next, Chloropac concentric tubular electrodes (CTE) generate sodium hypochlorite from the natural salinity in seawater, which eliminates the need to purchase biocides and store or replenish them onboard.
The SeaCURE system also features low energy requirements and low maintenance costs due to the self-cleaning feature of the CTE technology, the company says. Proprietary control logic monitors the biocide dose level necessary to provide the required efficacy depending on ballast water conditions.
The efficacy of the SeaCURE Ballast Water Management System is in accordance with International Maritime Organization (IMO) Convention D-2 regulations and exceeds the G8 and G9 Guidelines for Approval of Ballast Water Management Systems. In February, the Federal Maritime and Hydrographic Agency of Germany (Bundesamt für Seeschifffahrt und Hydrographie- BSH) granted type approval for the SeaCURE system.
Testing of the SeaCURE system was successfully completed at three separate installations each with widely differing ecosystems. Land based testing has also been undertaken at GSI and MERC; two independent test facilities that are US Coast Guard (USCG)-approved Independent Laboratories. Evoqua says it is well positioned to achieve US Coast Guard Type Approval on an expedited basis based on a submittal of existing data.
