BIO-SEA COMPACT BWMS RECEIVES USCG CERTIFICATION

Jan 28, 2022 | Water & waste management news

The Bio-Sea M-Series ballast water management system (BWMS) by the French Bio-UV Group has received type approval certification from the United States Coast Guard (USCG).

Certification followed the successful completion of tests under DNV supervision. The classification society evaluated and approved all technical documentation and paperwork. Bio-UV Group received IMO approval for the Bio-Sea M-Series in September 2021.

Charlène Ceresola, BWT Project Manager, said: “Technically, the core components and disinfection performance of the M-Series are identical to the B-Series, which received IMO approval in 2017 and USCG type approval in 2018. But because we have designed a new reactor, we needed an updated type-approval certificate. The previously approved B-Series incorporates a mono-lamp reactor, and several ‘B’ reactors need to be mounted in parallel to reach high treatment rates. This requires specific manifolds for hydraulic balance, which can take a significant footprint. The new Bio-Sea M-Series, however, is based on multi-lamp reactors, equipped with two-to-seven lamps in a single chamber, allowing a more compact design for the same capacity of treatment. A maximum of two reactors are installed in parallel.”

The Bio-Sea M-Series system has been specifically designed to optimise the footprint and installation costs of a medium flow rate ballast water treatment system. The M-Series incorporates fewer UV lamps and is believed to have the lowest height requirement of any UV-based system in the market.

Biodosimetric testing confirmed that an equal or higher UV dose can be achieved using the ‘M’ reactor compared to the earlier design. Environmental testing, completed at Force Technology’s facility in Denmark, verified the reactor’s robustness, design, and usability in a marine environment, especially with regards to vibration.

Florian Cortes, Technical Director, said: “Certification is vitally important to shipowners in the BWMS decision-making process. With this new certification, the USCG has confirmed the high-performance capability of our third generation BWMS UV reactor. The development of the ‘M’ reactor allows shipowners looking for a medium-flow rate BWTS to benefit from Bio-UV group’s proprietary UV water treatment technology.”

Available as a modular or skid system and with fewer piping components, the Bio-Sea M-series is available with a short lead time. Several units are already on the shelf for immediate delivery. As of January 2022, the Bio-UV Group has a current order book of over 100 Bio-Sea units, almost twice as many as the corresponding period in 2021.
