Treatment of odours generated by a water purification plant

Maxi Canada - Biosor

Client: Maxi Canada

The environmental expertise of the CRIQ serving food processing operations

Maxi Canada, a business founded in 1970 that is active in the field of processed chicken products, is located in the heart of the tiny municipality of Saint-Lin-Laurentides, near Montréal. Peaceful cohabitation with the neighboring populations represents a corporate priority with respect to the environment and sustainable development. For this reason, a few years ago it acquired a biofiltration system to process the odors generated by its wastewater purification plant.

This system, which since 2008 has integrated the BIOSORTM biofiltration technology developed by the CRIQ, was originally designed in steel containers, and over time, these containers were replaced in order to comply with the standards dictated by the ministère du Développement durable, de l'Environnement et de la Lutte contre les changements climatiques.

Convinced of the outstanding performance of BIOSORTM, Maxi Canada once again returned to the team at the CRIQ to head the management and production of major initiatives aimed at upgrading its treatment facilities for atmospheric emissions.

Accordingly, the CRIQ, in collaboration with its partners, designed the plans and specifications for a new air filtration system and supervised the dismantling of the existing equipment and construction of new bio filters in addition to providing the assistance required in order to obtain authorization certificates from government authorities.

The CRIQ will also be responsible for the assembly and start-up of the new BIOSORTM biofilters - 2 units each with a capacity of 15,000 Nm3/h - as well as for following up with and accompanying Maxi Canada over a period of 12 months.


- Choosing the CRIQ is reassuring, especially for projects that are
as important as those relating to the environment.
