System Validation & Research

atg UV Technology are committed to continuous innovation and product development. The technical aspects of the business are split in to two main sections Research and Development and Validations/Approvals . These topics are covered in more detail further down the page.

Validations / Approval Testing

atg are committed to providing Ultraviolet disinfection systems that deliver the required amount of UV for a given application. With this in mind along with the increasing pressure on facilities to assure sufficient treatment, atg have invested in Bio Dose Testing on selected product ranges. This enables atg to offer "Validated" systems.

atg UV Technology have a large number of validated UV systems to ensure UV disinfection performance.  Our validation testing has been carried out in accordance with the Untied States Environmental Protection Agencies, Ultraviolet Disinfection Guidance Manual (UVDGM). The EPA method is one of the most modern and rigorous testing regimes in the world, and offers a number of bennefits over other existing validation standards, such as increased flexible operation for validated equipment.

The US EPA UVDGM 2006 uses the mandate of the Safe Drinking Water Act to monitor emerging contaminants, under the Unregulated Contaminant Monitoring Regulation (UCMR2).  Aimed at water supplies originating from lakes, reservoirs, ground water aquifers and rivers, the purpose of the US EPA UVDGM legislation is to ensure populations are kept safe from emerging pathogens such as Giardia and Cryptosporidium, which have demonstrated enhanced resistance to conventional disinfectants such as chlorine.  There are now 17 species of micro-organism which are resistant to chlorine.  There are none that are resistant to Ultraviolet disinfection.

As an industry leader with considerable experience in supplying US EPA Validated UV systems for Cryptosporidium protection, atg UV Technology are well placed to support and advise all water companies on the application of the validated units into water disinfection strategies including; log reduction, RED Dose, installation into existing infrastructures, upgrades and retrofits, ongoing industry regulation and future product development.

atg UV have designed and developed a large range of UV systems specifically for municipal drinking water and waste water applications that are fully compliant with industry requirements.  Additionally our experience in the USA pools market has placed atg UV as an industry leader for validated swimming pool UV systems.  For instance in New York State USA, It is now compulsory to fit UV on spray-pad type aquatic features, as a result of atg UV's work with the New York Department of Health (DoH).   

Research and Development

At atg R&D is taken very seriously, we are continually looking for ways to improve our current product offering and investigate new ideas and processes in search of the more efficient and advanced fluid treatment systems.

atg are involved in many research and development projects both internally and in group research studies. We are currently working in a pan-European project investigating Ballast Water treatment systems. This research is being carried out to help safeguard the environment and reduce the impact of ships moving ballast waters around the world. This is an increasingly serious problem with a number of cases of ‘transported organisms' thriving in new environments to the detriment of native species.  atg UV also carried out a number of in house research projects looking at the use of UV for special applications or combining UV with other complimentary treatments to increase the efficiency of certain processes.
