Research Interests:

I am interested in sustainable wastewater treatment. Sustainable wastewater treatment provides economic and resource benefits over many current wastewater treatment practices where wastewater is considered to be a waste to be treated and then thrown away. This is both costly and inefficient. In sustainable wastewater treatment, wastewater is considered to be a raw material that can be converted to useful products such as energy, nutrients and especially water. Where possible, the water will be reused directly and only thrown away to the environment when no other options are available. Because the useful products may sold, the net economic cost versus current practice is reduced. Because the useful products reduce the demand for these products directly from the environment while also reducing the discharge of contaminants, the net environmental cost of sustainable wastewater treatment is also reduced versus current practice.


Anaerobic processes are key components of sustainable wastewater treatment. Oxygen is not required, biomass yields are reduced and energy can be recovered, usually as methane and possibly as hydrogen or even directly as electricity. My recent focus has been to develop more technically capable and cost-effective systems for the anaerobic treatment of wastewaters. In particular, we have been looking at anaerobic hydrogen production, anaerobic membrane bioreactors, and anaerobic sludge digestion, the latter in combination with energy production systems such as engine generators, microturbines, fuel cells, etc. Most of the work is experimental but computer models are developed and evaluated to help focus experimentation and provide deeper insights into underlying mechanisms.


In addition to energy, water for reuse is a key product of wastewater treatment. In conjunction with the Drinking Water Research Group at the University of Toronto, we have been examining the application of advanced membrane processes to remove endocrine disrupting compounds from waters. The high quality waters produced can be used for a variety of purposes.
