Pre-Commissioning Cleaning using the latest technologies

Guardian Water Treatment uses the latest technologies and innovations to deliver its pre-commissioning cleaning services.

These include innovative non-chemical treatment, Advanced Oxidation Technology (AOT) from Wallenius and Hydrosphere, both of which reduce reliance on chemicals and allow flushing and lower volumes of water.

AOT can be used on incoming mains supplies at the construction stage to provide a safe, environmentally-friendly and cost-effective alternative to chemical dosing of fill water.  AOT can also be used to control bacterial growth in existing water systems. By screening all water coming through the AOT device, chemical usage, especially biocides, can be reduced.

How does non-chemical water treatment work?

Wallenius AOT is a photocatalytic water purifier that greatly reduces bacterial levels in the water.  AOT uses a patented, chemical-free technology that is inspired by nature’s own way of purifying water. A specific frequency of light and photocatalytic surfaces are used to create free radicals that break down harmful microorganisms and other pollutants in water.

The Wallenius AOT process occurs within a closed chamber in which radicals are generated. These radicals are highly reactive so they instantaneously break down harmful micro-organisms and other pollutants. The radicals are short lived and exist for only a few milliseconds, which means they have no possibility of leaving the reaction chamber.

AOT units, when positioned and sized correctly, produce a log 5 reduction in Legionella bacteria levels within the water that passes through it.
