The first permanent US installation of a unique technology that can “smell” an odor problem before it occurs recently went on line in Tucson, Arizona, according to N.A. Water Systems, a Veolia Water Solutions &
Technologies company.
 

OdoWatch® is now operational at the Roger Road Wastewater Reclamation Facility, where six e-noses (electronic noses) calibrated to smell odors like the human nose are installed at the facility. The unit performs real-time air dispersion modelling to generate a colour-coded plume indicating the level of odour on a map of the site.
 

The odour is quantiied by the system, and if the level begins to approach the threshold that can be perceived as a nuisance by a human nose, an alert notifies operators that actions must be taken to mitigate the situation. OdoWatch® can also be used to determine which source at a facility is causing the alert.
 

Pima County’s OdoWatch system is a first for the United States. Pima County has also requested an OdoWatch System proposal for its Ina Road Wastewater Reclamation Facility.
 

Veolia Water Solutions & Technologies is the exclusive licensee of OdoWatch® technology in the water and wastewater treatment industry.
