Our Odor Experts will be on the floor showcasing unique Electronic Nose technology at the International Water Association (IWA) and Biofiltration Conference - a forum for the managment of environmental odors, air emissions, volatile compounds, and greenhouse gases.

5th IWA Specialized Conference on Odors and Air Emissions Jointly Held With 10th Conference on Biofiltration for Air Pollution Control

4-7 March 2013 San Francisco, California, USA

Expertise in odor, air emissions, sampling, measurement, odor control operations/maintenance, and biofiltration will be exchanged and shared at the show.

We, along with our Solution Partner KRUGER (a subsidiary of VEOLIA) will be at Booth #200 ready to show and discuss the advantages of deploying an Odor Monitoring and Tracking system.

The highlight of the conference is that our top industry experts have been invited to present: Thierry Pagé - Odotech CEO & President; Raymond Porter - Odotech Senior Odor Expert.

CEO Thierry Pagé will be presenting on March 5th at 2pm, on the installation of a continuous electronic nose odor montoring system in the city of Agadir, Morocco. 

The city of Agadir is Morocco's flagship tourist destination thanks to its long beaches of fine golden sand, pleasant climate throughout the year. It also has a port infrastructure and strong industry of seafood processing that becomes the major source of wealth for the city while unfortunately often being implicated as the source of odors.

By combining meteorological data with readings by electronic noses, the system implemented uses dispersion modeling and displays the odor plume which allows real-time monitoring of the odor levels of the city center and the tourist area, enabling the identification of sources responsible for odors while receiving alerts to odor incidents that have been confirmed by a companion questionnaire from nearby residents.

Senior Odor Expert, Ray Porter, will present on March 6th at 10am, on "The New Arithmetic of Odor: Non-Additive Plume Superposition in Continuous Multiple Source Emission Dispersion Monitoring".

His seminar will focus on the differentiating aspects of multiple source odor plume superposition. When using atmospheric odor dispersion modeling on multiple sources, the usual assumption is to consider that the plumes are additive. This approach is reasonable when the mass of conservative, non-reactive compounds are added to meet a compound specific standard. If a single odorant is being considered, such as hydrogen sulphide, and it is being compared concentration based standard.

In the assessment of odor impacts, the addition of odor concentrations from different odor sources is still the common practice. Knowing that there could be partial additions, synergies or inhibition of the blended odor emissions, the impact of the additivity assumption on the predicted plume extents is of interest. Different odorants may define the odor intensity from different odor sources. Combining the different chemical mixtures may not result in a linear, additive result. Combining controlled mixtures of odors from various sources would be evaluated by olfactometric analysis. A matrix of sources and mixing ratios would be evaluated. The data would be analyzed to determine whether the combine odor samples follow linear, logarithmic or non-linear trends.

The two topics being presented will be popular to attend and we recommend that you get there early to ensure a good seat!  

Visit Thierry, Ray or Sharon at our Booth #200. We will be happy to show a "Live demo" of a working Odor Monitoring system complete with Odor Dispersion Modeling.

The 5th IWA Conference on Odors and Air Emissions is taking place in San Francisco CA, from March 4-7th, 2013.

With its enchanting climate and its long beach of 10 km, Agadir has all you need for a great beach holiday. Agadir is a member of a private club of the Most Beautiful Bays in the World. It contains a marina that can accommodate hundreds of pleasure boats and a boardwalk with a stunning view.

Agadir also has a dynamic industrial port that coexists with a vibrant tourism industry. The management of air quality and odours becomes particularly strategic to ensure the quality of life for tourists and locals alike. Furthermore, Agadir seeks sustainability and growth of its industrial activities.

To addresss the issue of coexistence of the tourism and industry in the Agadir area, the Wilaya (county administration) of the Souss Massa Draa Region has set an objective to identify the real-time odour sources responsible for odour pollution experienced in the tourist zone & Agadir city center and  quickly take, in conjunction with industry, appropriate measures to address the sources and maintain comfort of the tourists and citizens of the city of Agadir.

In partnership with the Wilaya, Odotech has recently completed the installation of a regional version of the OdoWatch odor monitoring system for the City of Agadir.

The system consists of a network of electronic noses (eNose™) positioned in the industrial area of ​​Anza and the tourist area of Agadir. The industrial sites specifically covered by the odour monitoring are, for example, fishmeal plants, edible oil processing plant, coffee factories, fishing port and sewage pumping stations.

The managers of plants have access to real-time odour information, allowing them to work with the Wilaya to minimised and avoid the nuisance impact of odours.

The odour surveillance system was commissioned in January 2012 and is the first step of a much wider air quality program for City of Agadir and its suburbs.
