Berson Launches ‘OpenLine’ Open Channel UV Wastewater Disinfection Systems

New ‘plug-and-play’ modular system is 100% pre-engineered for wastewater applications

UV disinfection specialist Berson (www.bersonuv.com) has launched its new OpenLine range of open channel UV wastewater treatment systems. 100% pre-engineered for wastewater applications, the OpenLine range is specifically designed to treat secondary wastewater flows of up to 95,000 m3/day (approx. 4,000 m3/hour) over a wide range of UV transmittances. It utilises a new type of low pressure, high output (LPHO) amalgam lamp that offers stable UV output over its entire operating life of up to 14,000 hours.

The OpenLine range’s flexible, modular design means simple installation and maintenance, making it the ideal open channel UV system for municipalities with low flow requirements. Inspired by Berson’s successful InLine+ range of closed vessel UV systems, the OpenLine is the first ‘plug-and-play’ open channel UV system available on the market. Installation is straightforward: the unit is simply placed on a flat surface, the inlet and outlet piping is connected, and it is ready to use. The totally self-contained unit negates the need to install lamp wires through conduits or connect chemical feed systems.

Automatic, long-life Viton wipers, powered by a self-contained air compressor, keep the quartz sleeves surrounding the UV lamps clean, ensuring optimum UV output at all times. Wiper frequency is also easily adjustable. The system’s ballasts have a variable output between 50-100% and are easily accessible. In addition, the interface of the PLC control system can be customised by the user to suit their requirements. Lamp replacement and other routine maintenance tasks are also straightforward and can usually be carried out by on-site staff.

Berson is one of the few non-German UV system suppliers capable of providing a complete range of UV systems with capacities between 10 – 10,000 m3/hour, certified to the newest German DVGW* norm, W294, Parts 1, 2 & 3 – the highest standard currently possible in the world. The company’s UV systems are also validated to the UVDGM** and NWRI*** (for reuse applications) in the USA and Canada.

* DVGW (German Technical and Scientific Association for Gas and Water) is the body responsible for industry self-regulation in the German water and gas and water supply industry and its technical rules are the basis for safety and reliability.

** USEPA UV Disinfection Guidance Manual (UVDGM). The validation certifies the use of the systems for the Long Term 2 Enhanced Surface Water Treatment Rule (LT2ESWTR).

*** National Water Research Institute (www.nwri-usa.org) / American Water Works Research Foundation (www.waterresearchfoundation.org).
