BIO-UV’s new BWTS series receives USCG approval

Introduced last year, BIO-UV’s BIO-SEA M-Series ballast water treatment system (BWTS) has received a United States Coast Guard (USCG) type approval certificate.

The France-based UV water treatment specialist received the USCG certification last December, following the successful completion of tests under DNV supervision. The class society also evaluated and approved all technical documentation and paperwork.

BIO-UV Group received IMO approval for the BIO-SEA M-Series in September, 2021.

“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,” explained Charlène Ceresola, BWT Project Manager, BIO-SEA by BIO-UV Group.

“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,” she said.

Unveiled in June, 2021, the BIO-SEA M-Series system has been specifically designed to optimise the footprint and installation costs of a medium flow rate BWTS. The M-Series incorporates fewer UV lamps and has the lowest height requirement than any other UV-based systems in the market, the company claimed.

Bio-dosimetric testing also 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 Denmark facility verified the reactor’s robustness, design, and usability in a marine environment, especially with regards to vibration.

“Certification is vitally important to shipowners in the BWTS decision-making process,” said Florian Cortes, Technical Director, BIO-SEA by BIO-UV Group. “With this new certification, the USCG has confirmed the high-performance capability of our third generation BWTS 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,” he said.

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, this year, the BIO-UV Group had an orderbook of over 100 BIO-SEA units, almost twice as many, as the corresponding period last year.

Down the years, BIO-UV has seen success in the cruise and ferry sectors and a spokesman told ICSI that the ‘M’ series was ideal for fitting on board these type of vessels, depending on their flow rates.
