Over the course of the past two years, AUG has been working with the University of Toronto and the drinking water facility in the municipality of Smiths Falls, to test and refine its remote photonic sensing system for continuous monitoring of disinfection by-products (DBPs). The project is funded through SOWC’s Advancing Water Technologies (AWT) program, which is supported by the Federal Economic Development Agency for Southern Ontario (FedDev Ontario).

AUG’s system uses chemical reagents that change colour when they react with THMs, measuring those subtle changes with a photonic spectrometer. The results are ready in just 45 minutes. Thanks to that speedy feedback, plant managers can fine-tune chlorine, pH and coagulant levels, and keep zebra mussels in check without exceeding THM standards.
