An ecological and economic wastewater odour-control system for a healthier environment.

Alizair™ is a wastewater odour control system that provides staff with a healthy and safe environment to work in. It uses negative pressure and a deodorisation treatment (biofiltration) to collect polluted air. Alizair™ can achieve very high filtration rates (500m³/m²/h) with treatment loads that can exceed 50g/h/m³ of medial, and oxidises malodorous substances (organic or inorganic) into inorganic and odourless compounds.

Alizair™ is one of the least expensive odour-removal solutions and it is also very easy to use. It requires low maintenance and low reagent input, and is available in a wide range of flows. Its efficiency on mercaptans can be improved by the addition of downstream physical or chemical treatment.

Alizair™ is also available as compact units, ready to be used. There are four different sizes, with maximum flow ranging between 1,800 and 6,700 m³/h.
