Olfactometry Services and Expertise

For over 15 years, Consumaj has acquired expertise in olfactometry, by mastering all the stages of the analytical process. The engineers and technicians of Consumaj are also able to offer expertise in odour control strategies, to assist companies and groups in meeting requirements and standards.

Many companies and groups require odour dispersion modelling to meet odour emission standards and limit neighbourhood nuisance. Consumaj is well aware of laws and regulations governing odour emissions in Quebec as well as Canada. Consumaj can provide to its clients, odour control strategies developed through odour dispersion modelling. Such strategies can allow more production flexibility while limiting odour emissions to levels environmentally acceptable.

Whether the source originates from cooking operations, handling of chemicals, chimneys, emission diffuser, and waste or wastewater treatment facilities, whatever the source, Consumaj offers sampling and analytical services followed by an odour dispersion analysis to recommend odour control strategies adapted to the needs and operation of the client.

Odour control strategies need a systematic approach

Odour and emission sampling

Consumaj is well equipped to sample a wide range of sources, whether from a chimney or surface. Consumaj is also equipped with wind tunnels simulating the dispersion of a product over a surface.

Olfactometric analysis and odour characterization

Olfactometric analyses provide information on the character of sampled odours. The laboratories of Consumaj are equipped with ONOSE-8®, a state-of-the-art stationary dynamic olfactometre. Design, manufactured and operated by the engineers at Consumaj, ONOSE-8® is one of the most consistent and reliable olfactometre produced in Canada.

Atmospheric Dispersion Modelling

Once the odour or emission source is sampled and analyzed, its properties can be inserted into an atmospheric dispersion model to predict its nuisance level on the neighboring buildings, based on prevailing winds.

Dispersion models generally provide the following information:

  • Compare the levels of emissions to those accepted by regulations.
  • Identify the nuisance impact of the emission on the neighborhood.
  • Establish the attenuation level required to practically eliminate all neighborhood nuisance.
  • Optimize emission remediation measures and investments.
  • Produce emission dispersion diagrams to optimize the location of a new installation and minimize its emission nuisance.
