UV disinfection systems receive additional validation

Berson says that the validation certifies the use of the systems for the Long Term 2 Enhanced Surface Water Treatment Rule (LT2ESWTR) released by EPA in November 2006.

“We are delighted to have achieved this important validation as it confirms our position at the forefront of UV disinfection technology for drinking water and wastewater applications,” commented Berson’s managing director Andrew Clark.

He added that Berson products are no longer subject to any Cryptosporidium or Giardia patent fees for UV disinfection applications worldwide.

The testing was conducted by Carollo Engineers at its Portland, Oregon validation facility in the USA and covered a three-dimensional matrix of UV transmittance, flow and reduction equivalent dose, using both T1 and MS-2 phage test surrogates. Dose delivery equations were derived for all reactors that predict T1 and MS-2 RED as a function of flow, UV-T, UV sensor readings, and microbe UV sensitivity.

Berson adds that it is only one of a few UV system suppliers capable of providing a complete range of UV systems with capacities between 10 – 10,000 m3/hour, certified to the newest DVGW (German Technical and Scientific Association for Gas and Water) norm, W294, Part 1, 2 & 3 – the highest standard currently possible in the world.
