A team from IRDA and CRIUCPQ has been working on developing an air treatment unit to reduce pig farm emissions. The objective of the project was to improve the existing experimental design to produce a commercial unit that is cheap to install and operate.
The first phase of the project was aimed at adapting the design of the air treatment unit (ATU) developed by IRDA to produce a commercial unit to be installed at a pig farm. Based on the new concept, we evaluated the efficiency with which the ATU captures standardized dust particles, artificially suspended virus models, and aerosols naturally generated on pig farms. The long-term performance of the ATU on a commercial scale was then evaluated. The last phase of the project was a cost-benefit analysis of this technology.
From 2016 to 2018
Air quality, Coexisting in an agricultural environment
This technology developed by IRDA minimizes the spread of infectious diseases and reduces odours generated by swine production.

The aim of this project is to show that efforts made to better distribute phosphorus on the land are effective and that the indicators used to determine phosphorus saturation thresholds are correlated with soil phosphorus balance and dynamics.
