Wastewater treatment plants are microbial jungles, with each site containing more than 10 million different microorganisms. Learning what’s in our wastewater can help reduce pollution more effectively and at a lower cost.
Household wastewater is commonly processed through physical filtration, and chemical and biological treatments. Despite sophisticated processes and monitoring systems, big disruptions from bulking and foaming bacteria still occur, especially during the summer months. Bleach or additional chemicals are often required to manage the microbes that cause the foaming.
Earlier this year, University of British Columbia researchers Dr. Steve Hallam and Dr. Ryan Ziels completed a pilot of an eDNA-based monitoring study with the wastewater facility at the City of Kelowna. Their successful study revealed which bacterial communities are causing the bulking and foaming issues. Detailed information from eDNA also provided information to tailor their treatment strategies to mitigate future operational disruptions.
Now, plant managers have specific information for targeted strategies to reduce pollution.
Different municipalities can now adopt this technology at a low cost. The researchers are developing low-cost protocols to enable near-time microbial monitoring using a handheld sequencing device that costs around $1,300. View the device starter pack.
