Bio UV launches new M-series BWTS

The new M-Series BWTS incorporates a novel reactor arrangement designed to increase the flow rate capacity of existing technology without the need for any manifolds.

BIO-SEA has modified the design of its reactors so that they incorporate a greater number of the BWTS supplier’s preferred medium pressure UV lamps. This development of the ‘M’ reactor itself is based on the same technology inherent to previous incarnations of the BIO-SEA system. As a result, certification of the system is not expected to be problematic. IMO and USCG certification documents are imminent. The environmental testing and UV dosage tests have been done under DNV supervision.

The refined system offers significant benefits from a customer’s point of view, as Xavier Deval, Business Director – BIO-SEA explained. The system footprint and integration costs have both been reduced by at least 25%.

“With the M-Series we see a significant benefit in terms of size, capacity and installation simplicity. 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 flowrate,” Deval said.

Despite the inclusion of additional lamps within the system’s reactors, the longitudinal based BWTS system continues to require fewer UV lamps than competing perpendicular systems in the market, Deval noted.

A range of ‘M’ reactors have been designed for different capacity requirements. These include the M02 for flow rates between 190 and 300m3/h, the M04 for 500 to 600m3/h flow rates, the M05 (500 to 750m3/h), M07 (760 to 1040m3/h), M08 (1040 to 1200m3/h), M10 (1040-1500m3/h), and the M14 for 500-2100m3/h flow rates.

“For a 300m3/h capacity system we can treat the volume with just one two-lamp M02 reactor. For a flow rate of 1040m3/h one seven-lamp M07 reactor would do the job, while a pair of these will be able to deal with 2100m3/h. With the installation of additional reactors, a maximum flow-rate capacity of 4000m3/h can, theoretically, be achieved.”

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 containerships, bulk carriers, multi-cargo vessels, cruiseships, passenger ferries, offshore vessels, navies ships and mega-yachts.
