BIO UV Group has designed a new series of BIO-SEA ballast water management systems (BWMS) compatible with flow rate requirements of up to more than 2,100 m3 per hour
The M-Series BWMS incorporates a novel reactor arrangement designed to increase the flow rate capacity of existing technology without the need for any manifolds.
“This is a huge development in ballast water treatment,” said BIO-UV BIO-SEA Group business director Xavier Deval. “With the M-Series, we see a significant benefit in terms of size, capacity and installation simplicity.”
He added, “A manifold-free design allows shipowners to optimise installation time and costs dramatically, while keeping the number of reactors required to an absolute minimum; only one or two depending on the required flow rate.”
Speaking in an online event marking the official introduction of the M-Series, Mr Deval explained that while the new version is based on the same technology inherent to previous incarnations of the BIO-SEA system, it is the development of the ‘M’ reactor itself that has allowed the company to advance the product.
“The evolution of the BIO-SEA system means shipowners and shipyards now have a high-capacity ballast water treatment system from a unit that incorporates fewer UV lamps than competing systems in the market,” said Mr Deval.
“For a 300 m3 per hour capacity system we can treat the volume with just one two-lamp M02 reactor. For a flow rate of 1,040 m3 per hour, one seven-lamp M07 reactor would do the job, while a pair of these will be able to deal with 2,100 m3 per hour. With the installation of additional reactors, a maximum flow-rate capacity of 4,000 m3 per hour can, theoretically, be achieved.”
A range of M reactors have been designed for different capacity requirements. These include the M02 for flow rates between 190 and 300 m3 per hour, the M04 for 500 to 600 m3 per hour flow rates, the M05 (500 to 750 m3 per hour), M07 (760 to 1,040 m3 per hour), M08 (1,040 to 1,200 m3 per hour), M10 (1,040-1,500 m3 per hour and the M14 for 500-2,100 m3 per hour flow rates.
In effect, BIO-UV Group has, together with its own integrated engineering department, developed a downscaled version of its existing UV technology to reduce system footprint and integration costs by at least 25%.
All environmental testing and UV dosage tests have been done under DNV supervision. IMO and USCG certification documents are imminent.
Available as a modular or skid system and with fewer components resulting in a reduced risk of corrosion, the M-series is available with a short lead time. A number of units are already on the shelf for immediate delivery.
BIO-UV Group will continue to manufacture and support the BIO-SEA B-Series, since there are components and spare parts common to both treatment systems.
Several hundred BIO-SEA installations are currently operating worldwide on a wide range of vessel types, including container ships, bulk carriers, multi-cargo vessels, cruise ships, passenger ferries, offshore vessels, naval ships and mega-yachts.
