Research Areas

Horiba XploRA PLUS RAMAN Microscope

At the DWRG we conduct a lot of micoplastic research. We are able to complete detailed analyses of waters containing microplastics with our Horiba XplorRA PLUS Raman microscope in our lab.


Water containing potential harmful algal blooms. Professor Hofmann leads research that investigates the impacts of cyanotoxins and cyanobacteria on water quality.


Magnified photo of daphnia which can be used to monitor fluctuations in water quality, especially in relation to aquatic toxicity testing.


Zebra and quagga mussels in student-made bioboxes used for research on these invasive species, and how they affect water treatment plants.


An ozone generator at one of our partner water treatment facilities. We study advanced oxidation techniques to better improve water quality.


Water collection at our partner sites and transport back to our UofT labs is a regular part of graduate studies. We work with many water treatment plants all across southern Ontario and beyond.

We are involved in a wide range of projects with our research partners. Some of these projects are seasonal, while others span multiple years. A few examples of the recent topics include:

  • Microplastics in drinking waters
  • Biologically active filtration
  • Ultrafiltration fouling minimization strategies
  • Inactivation of emerging pathogens
  • Synergy of multiple disinfectants
  • Disinfection of reuse waters
  • Advanced oxidation processes
  • Secondary disinfection, impacts on biofilm and corrosion
  • Control of disinfection by-products
  • Computational fluid dynamic modeling of dissolved air flotation
  • Use of fluorescence techniques to improve process control
