Evoqua atg UV are experts in the application of Ultraviolet light, offering both medium pressure and low-pressure amalgam lamp technologies. This allows for high quality, cost-efficient solutions for a variety of applications.

Flexible designs ensure atg UV can provide advanced technology solutions for both new installations and retrofits of existing units, in a range of difficult and challenging environments.

With a vast product range, which caters for a variety of applications, from only a few m³/hr to full-scale water treatment works treating in excess of over 2500 m³/hr in a single compact system, atg UV can provide effective solutions for almost any specification.

In addition to our standard products, atg UV can offer United States Environmental Protection Agency (US EPA), Ultraviolet Disinfection Guidance Manual (US EPA UVDGM) Validated systems. The US EPA method is one of the most modern and rigorous testing regimes available for UV systems, allowing for flexible operation of the Validated UV equipment.

atg UV utilises advanced 3D CAD and CFD model production to aid Ultraviolet chamber designs and lamp orientation, ensuring our units achieve optimum performance.


ATG deliver world-leading medium pressure and ultra-high output, low-pressure amalgam UV disinfection systems for drinking water and turn-key packaged plants for potable drinking water.

With independent third-party validated performance, UV disinfection is an accepted and widely used method for the primary disinfection products of potable drinking water.

Specialising in both ultra-compact, medium pressure (polychromatic) UV systems and ultra-high output, low pressure amalgam (monochromatic) UV systems, ATG UV design and manufacture UV disinfection systems, integrated UV plants and mobile, turn-key UV packages for some of the worlds’ largest municipal water treatment works, treating over 240 MLD (10,000 m3/hr).


UV disinfection is now a standard final treatment stage in wastewater treatment plants worldwide and is widely favoured due to its environmentally friendly, chemical-free ability to provide high-log reductions of all known micro-organisms, including chlorine resistant strains.

As growing environmental awareness and stricter regulations drive effluent discharge standards and water re-use initiatives to achieve greater performance, UV disinfection is fast becoming the treatment of choice on many wastewater streams.


UV is proven to significantly improve swimming pool water quality by breaking down problem chloramines, the cause of eye and skin irritations and protecting against harmful chlorine-resistant microorganisms such as Cryptosporidium and Giardia.

For operators wanting bright sparkling water, fresh clean air and residual chlorine levels as low as 0.5ppm, UV has become the treatment technology of choice worldwide for swimming pools, spas and water parks.



UV light is a chemical free treatment that cannot be overdosed, ensuring the physical characteristics of the water, such as PH levels and temperature, remain unchanged whilst avoiding the introduction of harmful toxins, such as chlorine into the environment. No micro-organism is known to be immune to

UV, it is non-selective in the destruction of all waterborne bacteria, pathogens, viruses and micro-organisms.


Specially designed and developed for food and beverage production, chemical–free ultraviolet water treatment eliminates all types of water-borne micro-organisms, including bacteria, moulds, yeasts, spores & viruses. Critically, UV treatment does not affect the organoleptic properties of water and other liquids, providing high rates of disinfection without any changes to taste, PH, texture and odour.


Water is used at some point in almost every manufacturing process worldwide. In many industrial applications, the use of chemicals such as chlorine or biocides is restricted for process reasons. UV provides a highly effective, chemical-free disinfection solution for a vast range of industrial applications.
