WATER TREATMENT SYSTEMS
Low flow ballast water treatment BIO-UV AWARDED USCG AND IMO TYPE APPROVAL FOR NEW SYSTEM BIO-UV GROUP HAS RECEIVED IMO AND USCG TYPE APPROVAL FOR ITS NEXT GENERATION LOW FLOW RATE BALLAST WATER TREATMENT SYSTEM RANGE.
T
he BIO-SEA L Easy-to-Fit system had to undergo new type approval testing as it incorporates a completely new UV-reactor. It has been designed specifically to meet market demand from the luxury yacht, expedition cruise and offshore vessel segments, where ballast water pump flow rate capacities are often under 100m3/h. The system has now received IMO and USCG type approval. “We are pleased to have received type approval from both the International Maritime Organisation and the US Coast Guard for this new ballast water treatment system”, comments Benoît Gillmann, BIO-UV Group CEO and Founder. “This development really sets us apart from our competitors in the market. BIO-SEA L Easy-to-Fit is the smallest BWTS purpose-built for low flow rates.”
Completely new system
According to Mr Gillmann, some ballast water treatment plants marketed as a lowflow rate system are in fact the same systems designed for larger capacities. However, they simply treat lower volumes using the same, high-power consuming, higher wattage lamps. “BIO-SEA L, however,
is not derivative of the company’s existing BIO-SEA B product and is based on a completely new 6kW UV lamp arrangement, sized to guarantee full compliance while treating flow rates of between 20m3/h and 90m3/h (USCG mode) and up to 120m3/h in IMO mode”, explains Mr Gillmann. A key change is the UV lamp and casing materials used in the new system. One 6kW lamp can treat ballast water flows of up to 30m3. A further one or two lamps can be added to the BWTS skid for flow rates of 60m3 and 90m3, respectively.
Low CAPEX and OPEX
Based on the experience gained from BIOSEA B range (50 to 2,000 m3/h) which received USCG type approval in 2017, the France-headquartered system designer and manufacturer says the development provides ship operators with more competitive ballast water treatment with low CAPEX and low OPEX. “Everything has been adapted to suit the lower flow rates of the smaller vessel,” states Mr Gillmann. Technical and R&D Manager Xavier Bayle adds: “These benefits have been achieved as a result of the unique design of our reactors. Each BIO-SEA L Easy-to-Fit unit
