Aquilair™ is a physical and chemical de-odorisation process developed by OTV, a subsidiary of Veolia Water Solutions & Technologies. This process entails the transfer of odorous gaseous molecules to a liquid phase.
Physical and chemical deodorisation
Principle
The Aquilair™ process chemically treats dirty air in a counter flow system with aqueous solutions. This takes place in wet scrubbers operating in series. Within the scrubbing towers, an inert material enhances the contact between the gas and the liquid.
Depending on the properties of the component to be removed, a neutralising agent (base or acid) is added to the treatment water to accelerate gas-liquid transfer and therefore the treatment efficiency. The addition of an oxidising agent accelerates this transfer process on the one hand, and regenerates the wash water on the other, while modifying the absorbed molecules.
Performance
- Aquilair™ is designed to treat highly concentrated gaseous effluents that may have concentration of odorous components as high as 100 mg/m3.
- This highly reliable technique achieves treatment levels in excess of 99%, ensuring the total absence of odour-induced pollution.
- The characteristics of the packed bed (properties, specific surface area, volume, height) are designed to optimise the gas-liquid contact time as well as the transfer of molecules.
