OdoWatch® - Odor Monitoring For Improved ControlSource: Veolia Water Solutions & Technologies
Kruger’s OdoWatch®, by Odotech, is the world’s first real-time, continuous odor monitoring technology. OdoWatch combines odor detection with wireless, automated instruments, to capture continuous emissions and weather data. With installations in the U.S., Canada, Europe and South America, OdoWatch provides wastewater treatment plant managers with the tools needed to prevent and manage odors before they can become a nuisance to neighborhoods within close proximity.
An OdoWatch® system is comprised of electronic noses (e-noses), a weather tower, a preconfigured computer, OdoWatch® software with AERMOD, and a communication system that transmits data to the computer.
How It Works
E-noses are positioned near odor sources at the site to measure odors continuously. The sensors within the e-noses are calibrated to recognize and quantify in odor units the odors of each site. The standards used for the measurements are ASTM E-679-91 and European Standard EN13725.
Veolia Water is the exclusive licensee of OdoWatch® technology in the water and wastewater industry.
The odor data from the e-noses are transmitted to a central control unit (CCU) – a computer preconfigured to analyze the information. A weather tower at the site also sends data to the CCU.
The CCU combines the weather data with the odor data and uses proprietary software along with AERMOD (an air dispersion modeling program) to display the intensity of the odor as a color coded plume overlaid on a map of the site displayed on the computer screen. Thus operators can see the odor intensity. In addition, an alert button at the top of the screen will activate when the odor intensity begins to approach the level at which a human nose can detect it.
In this way, operators are warned when the weather conditions and odor emissions combine to create a situation in which odor complaints could arise. The early warning enables the operators to make process adjustments, use odor treatment chemicals, or take other proactive steps to prevent nuisance odors.
