Controlling odor nuisance with electronic nose: 3 good reasons
Posted by Veronique Cadieux on Fri, Oct 28, 2011 @ 10:43 AM
1.Emission rates are extremely variable for some sources (a large number of distinct samples would be needed to have a clear picture of the variations), an e-Nose can:
-Provide a tool to track fluctuations and trends;
-Allow for immediate reaction and pro-active actions;
-Improve understanding;
-Focused efforts towards the real issues… reduced odour management costs.
Tracking Real-time Odours
2. Real time modelling will present the current situation:
-Which periods and conditions are putting the facility at risk;
-Enables activity planning (i.e. first phase windrow turning, screening…);
-Ensure odour events are minimized ;
-Allows for production increases in optimal periods.
3.System can be programmed with alert points:
-Monitoring of odour concentration at a nose/source or modelled off site odours at specific points;
-Operator is actively informed (alert);
-Neutralizers could be activated, additional aeration (or closure of a fan), startup of a treatment system, etc.;
-Leads to reduced operational cost and rapid response.
Testimonial
“Allowed us to rank odour sources and to set up corrective actions”
“Good correlation between the complaints and the system’s data”
“The real time plume allows for visualisation of our odour impact at all times, more useful and relevant than met tower info”
“My monthly survey can be correlated with the Odowatch information”
“Odour events are avoided by planning around unfavourable conditions”
