AOP Pilot specific technology

Ozonia’s AOP pilot plant is designed for clients seeking validated performances for the treatment of highly recalcitrant pollutants.


Equipped with an Ozonia high concentration OZAT® ozone generator and an Ozonia Aquaray® LPHO UV system, the AOP Pilot plant
is able to perform and compare five AOP processes through multiple reactors with all the ancillary equipment necessary to operate and monitor the specific AOP process under study.
In the Photochemical reactor, UV radiation is applied to the water saturated with ozone and/or H2O2 to generate hydroxyl radicals. In the
Chemical reactor, H2O2 is dosed to the ozonated water at multiple points for complete and continuous hydroxyl formation.

 

The effect of the oxidation processes and the water quality is monitored by means of on-line O3, UVT, H2O2, pH, redox potential, and offline COD measurements. Numerous sampling valves after the reactor vessels allow taking samples for ex-situ analyses throughout the treatment process.

How it works

AOP’s are aqueous phase oxidation methods consisting of highly reactive species used in the oxidative destruction of target pollutants. AOP
creates a more powerful and less selective secondary oxidant, hydroxyl radicals, in the water.

 

This secondary oxidant can cause the oxidation of most organic compounds until they are fully mineralized as carbon dioxide and water.
The hydroxyl radical has a much higher oxidation potential than ozone or hydrogen peroxide and usually reacts at least one million times faster,
thus leading to a smaller contact time and footprint.
