Aquilair™ Odour Control System

Biological deodorisation process ensuring the total absence of odour-induced pollution.


Aquilair™ is a physical and chemical deodorisation process based on the transfer of odorous gaseous molecules to a liquid. It comprises one or more successive washes of polluted air in a counter flow system - via aqueous solutions - in wet scrubbers operating in series. These scrubbers are filled with inert material watered with the chemical solution, which enhances the contact between the gas and the liquid.

Aquilair™ treats highly concentrated gaseous effluent which may have concentrations of odorous components as high as 1g/m³. This highly reliable technique enables you to achieve treatment yields in excess of 99%, ensuring the total absence of odour-induced pollution. The scrubber packing material characteristics (type, specific area, volume, depth) are selected to optimise the gas-liquid contact time and molecule transfer.

Aquilair Odour Control System

Wastewater treatment, water purification and sludge treatment processes can all be sources of visual, audible and olfactory pollution. This can be particularly bothersome if treatment plants are situated in towns or close to residential areas. Effective odour treatment is essential.

Aquilair is a chemical deodorisation technology that transfers the odour molecules to a liquid, thus preventing them from being released into the air. It is effectively used to treat highly concentrated gaseous effluents, guaranteeing the total removal of odour pollution.
