Research Project Targets GAC Filters With Longer Lifespans

A Ph.D. student at the University of Toronto's Faculty of Applied Science & Engineering is researching innovative solutions to address taste and odor issues in drinking water treatment. The student, Maeva Che, is particularly interested in extending the lifespan of granular activated carbon filters used in water treatment facilities. GAC filtration is an effective process, but replacing the filters after three years is inconvenient and expensive. The research focuses on promoting biodegradation of contaminants within the GAC filters. By encouraging the growth of beneficial bacteria on the GAC, the filters may not need replacing as often, reducing costs for treatment plants. The project is
