Purifying wastewater with less energy and cost
Share this story

Queen’s University researcher Philip Jessop is using advanced technologies and materials to develop a low-energy and cost-effective process to purify agricultural and municipal wastewater. The method uses captured energy from waste heat emissions to power the purification process. Jessop’s work builds on a previous project where he developed a method to purify industrial wastewater.

Jessop is collaborating with industry partners, including GreenCentre, Forward Water, Hatch and Kingston Utilities, as well as professors Michael Cunningham (Chemical Engineering) and Pascale Champagne (Civil Engineering), to develop the technology for commercial use. The new technology will be designed to ensure it has the capability to take water that is heavily polluted and make it safe for drinking.

"At present, industrial methods to produce drinking water from sea water or agricultural waste water are very costly – both in energy and in dollars. In our process you can use waste heat – such as the energy lost as heat from a factory or industrial plant – as the primary energy source for our process instead of electricity. For electricity, you will pay top dollar. If you can use waste heat, you may wind up using the same amount of energy, but in terms of dollars spent you’re using a lot less.”
