BIO-UV group unveils Bio-Sea Mini Ballast water treatment system for low flow market

To meet demands for ballast water treatment systems from operators of workboats, yachts, research ships, offshore service vessels (OSVs), and similar sized vessels, ultraviolet (UV) based water treatment specialist BIO-UV group has introduced UV BWTS, reportedly the smallest in the marketplace.


The new BIO-SEA L01-0030 Mini is said to be more compact than the company’s existing low-flow BIO-SEA L range. It is a fully automated filtration with a UV based system designed to treat ballast water flow rates from 13-30m3/hr from a unit that has a skid footprint of 1m2.

Part of its ‘L’ range for flow rates from 13-120m3/hr, the addition of the new L Mini gives a low-flow BIO-SEA BWTS for processing capacities below 30m3/hr.

“We have been able to reduce system footprint and overall size without impacting performance,” said Pierre Decloedt, technical director, BIO-SEA by BIO-UV group. “We added component flexibility and reduced the height of the system, a consideration when trying to fit a ballast water treatment system into a small machinery space.” He added that the L01-0030 Mini is the “smallest, most compact BWTS” “designed for this market sector”.

Reportedly chemical-free with zero active substances and by-products, the BIO-SEA Mini has been tested in low UV water transmittance conditions with performance unaffected by water temperature and salinity.

With a white gloss finish, CuNiFe pipework, high quality components, filter choices, and drip tray as options, the L01-0030 Mini can be delivered as a covered skid allowing for installation in areas outside the machinery room, such as the hangar, garage, or an open space. A loose component modular version is also available.

“There are space constraints on newbuild yachts. But we have listened to builders, managers, and owners to produce a compact, automated, plug-in-and-play BWTS that meets their dimensional and performance requirements,” he said.

BIO-SEA Unit Director Maxime Dedeurwaerder added that the development originates from a technical management company’s request to source a BWTS compatible with the machinery space dimensions of a yacht undergoing refit.

With four firm orders since the launch in July, two of these orders are said to be for newbuild superyachts. Dedeurwaerder said that a Mediterranean yard to refit a 33m yacht with a BIO-SEA L01-0030 mini modular version is also in discussion. He said, “If the project moves forward, it would be the smallest super yacht equipped with BIO-SEA BWTS.”

BIO UV goup has a range of certified UV based BWTS for different types of vessels and ballast water flow rates. The France-based listed company also provides 3D scanning, design, installation, commissioning, maintenance, and aftersales services as part of a complete turnkey BWTS package.
