Full certification for drinking water, in accordance with U.S. Environmental Protection Agency (USEPA) standards, has been granted to Berson closed vessel UV water disinfection technology, represented in Australia by CST Wastewater Solutions.
Michael Bambridge Managing, Director of CST Wastewater Solutions said “This validation is important as it confirms our position at the forefront of UV disinfection technology for drinking water and wastewater applications.”.
“Adopters of the Berson closed vessel UV technology in Australia now have no need to carry out their own independent validation testing of the disinfection system for water re-use and potable water systems , as they have test results that they can depend on.
“This gives buyers the assurance of knowing that their Berson UV system will meet the requirements of the very latest and most stringent international water re-use and drinking water standards,” he said.
UV closed vessel disinfection is increasingly being used as an augmentation or substitute for traditional chlorine disinfection, especially as concerns grow over the possible carcinogenic effects of chlorine. While traditional methods are still widely employed for drinking water purification in Australia, UV disinfection is gaining in popularity.
We are proud that the Berson state-of-the-art UV disinfection systems meet the very latest and most stringent drinking water standards.”
The testing, conducted by Carollo Engineers at its Portland, Oregon validation facility, met the standards of the USEPA’s UV Disinfection Guidance Manual (UVDGM). This certifies the use of the systems for the Long Term 2 Enhanced Surface Water Treatment Rule released by the USEPA in November 2006.
Testing 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 from all reactors that predict T1 and MS-2 RED as a function of flow, UV-T, UV sensor readings and microbe UV sensitivity.
Berson is one of the few UV system manufacturers capable of providing a complete range of UV systems with capacities between 10 – 10,000 cubic metres per hour, certified to the newest German DVGW norm, W294, Part 1, 2 & 3 – the highest standard currently possible in the world.
Closed vessel UV disinfection systems are easy to install within existing pipework, so there is minimal disruption to plant operation. Day-to-day operation is simple and maintenance is minor. The only regular requirement is changing the UV lamps and wiper rings once a year, a straightforward operation that can be carried out by on-site personnel.
