Wallenius Advanced Oxidation Technology (AOT)

Wallenius Advanced Oxidation Technology (AOT) is a patented water treatment system, providing a non-chemical alternative to water purification. A safer and greener option compared with traditional chemical water treatment, Wallenius AOT has been proven to kill 99.999% of Pseudomonas and Legionella bacteria and is ideal for pre-commissioning cleaning and general water treatment.

Suitable for workplaces, public buildings – such as hospitals and nursing homes – facilities where water is used as part of the manufacturing process, and leisure spaces, AOT has a very small footprint and can be used to purify water for a range of applications, including cooling towers, HVAC systems, sanitation, plumbing and drinking water.

AOT chemical-free water purification explained

Wallenius AOT utilises a specific frequency of light together with photocatalytic semi-conductor surfaces, to produce free radicals – just like nature does with sunlight. These reactive radicals break down harmful micro-organisms and other pollutants in water. The entire process is instant, taking just a few micro-seconds and adds no chemical by-products to the system water.
