Scentroid has been awarded a contract to install a network of Scentinal Compact Air Quality Stations, Gas Chromatograph Analyzers, and live dispersion modelling software to provide real-time odour monitoring. The system employs Chromatotec’s Medor line of sulphur compound isothermal GC analyzers. It is capable of detecting H2S, DMS, MM, and 12 other compounds to sub ppb accuracy.
The data is then fed to Scentroid’s odour prediction algorithm. This uses deep learning technology to map sensor data to numerous SM100i field olfactometry readings. The ultimate goal is to determine the odour concentration in OU/m3. Additional Scentinal SL50s are placed for direct emission measurements of high odorous sources. The locations tend to be aeration tanks, Inlet works, and sludge dewatering. The SL50s have the same built-in deep learning algorithm that will calculate the odour concentration of the gases being emitted.
All data is sent to Scentroid’s Total Odour Management System (TOMS). TOMS utilizes logic algorithms to continuously update a live air dispersion model. Metro Vancouver can now not only detect changes to process emissions instantaneously but also verify complaints, predict odour episodes and even optimize process variables to achieve minimal odour impact.
