Advanced Oxidation Processes - AOP
The oxidising properties of ozone, which stimulate the biological purification of pure oxygen and possess considerable refrigerating power, together with the chemical inertia of liquid nitrogen, constitute the basis of the modern environmental recovery technologies offered by SOL for the control of emissions and the decontamination of contaminated areas.
In groundwater treatment, and in particular in Pump & Treat technology, the use of ozone produced from pure oxygen permits the oxidation of several chemicals contained in the water following contamination, such as phenols, long chain hydrocarbon compounds and non-biodegradable COD.
In Bioventing treatment, the use of pure oxygen or air enriched with pure oxygen, can significantly accelerate the kinetics of the biological oxidation reactions, shortening the time needed for decontaminating the area in question.
Groundwater containing certain types of pollutants, especially volatile chemicals (e.g. chloride solvents), can be subjected to stripping treatment with air to lower the concentration of these pollutants in the water; they are transferred to the air which is then subjected to a cryogenic elimination process using liquid nitrogen to condense the pollutants and make them easy to remove and send to specialised treatment plants.
The technologies offered by SOL not only makes it possible to effectively treat emissions or decontaminate treated sites, but also guarantees considerable flexibility in the choice of timing and the operational methods adopted when managing the activity, thus achieving the same results but with improved control and shorter treatment times.
