OdoWatch system

1 electronic nose, OdoWatch® software for modeling atmospheric dispersion of odors, weather tower

Background

For over 30 years, the rendering plant has collected and processed animal waste from livestock and slaughterhouse operations from 14 counties in south-western France. Located in the town of Passage near Agen, the plant began early its investigation into understanding and reducing its odoriferous emissions.

Odotech Assignment

Odotech began by installing a continuous odor measurement OdoWatch® system consisting of 1 electronic nose. This was used to measure the emissions from the biofilter deodorization process, within the buildings. This source of odor had been identified by the members of the neighborhood committee, coordinated by Odotech, as the main source of perceived olfactory distress, a result supported by measurements taken during the initial site reconnaissance.

Principal Outcome

Rather than reinvest in processing solutions to reduce odor impacts, the rendering plant focused on optimization of biofilter performance using the measurements provided by the OdoWatch® system. The work performed allowed them to noticeably reduce the concentration levels of their emissions and to smooth the previous fluctuations in the efficacy of the deodorizing process.
