Odour Treatment

Controlling wastewater odours

Although intended to help protect the environment, pumping, water purification and sludge treatment stations can themselves be a source of visual, auditory or olfactory pollution, particularly when they are located in towns, residential areas or tourist destinations.

Veolia Water Technologies helps municipal clients respond to odour concerns and control wastewater odours at and around treatment plants.

Electronic monitoring

OdoWatch® technology

The "electronic nose network", OdoWatch®, continuously merges odour data with incoming weather data to display odour plumes on an on-screen map of the site and its surroundings. The system identifies main odour sources and can distinguish between site-generated odours and those originating from other sources.

With weather forecast data, OdoWatch® can project odour impact up to 24 hours beforehand, enabling the operator to take appropriate steps to prevent the predicted impact.

Process solutions

Aquilair™ physical and chemical deodorisation


Aquilair™ is a physical and chemical deodorisation process in which gaseous molecules are transformed to a liquid phase.

Alizair™ biological odour removal system


Alizair™ is a "green," biological odour removal system that uses bio-filtration to oxidize odourising molecules in a liquid medium.

These methods are incorporated during the design stage for new installations but can also easily be added to existing plants.
