Research in Environmental Engineering encompasses three areas: water treatment, wastewater treatment and solid waste disposal and management. The work serves the vibrant communities in the Prairies with special challenges of advanced nutrient removal from water and wastewater; cold climate issues; water and wastewater treatment in remote locations; landfill bioreactor issues. Examples include: particle analysis in water and wastewater; floc properties in dissolved air flotation; biological nutrient removal from wastewater and sludge liquor; novel biofilm membrane processes; biosolids processing and disinfection; anaerobic treatment processes; animal residue treatment; fermentation to generate carbon for biological phosphorus removal; clogging of leachate collecting pipes; and bioreactor landfills.
The environmental engineering program and the new laboratory offer the latest in instruction and facilities for studying the physico-chemical and biological transformation of pollutants in water, wastewater and solid waste. In particular, the program aims at developing the principles of reactor and process engineering for the treatment of water, industrial and municipal wastewater and solid waste. State-of-the-art analytical equipment includes, among other, high performance liquid chromatographs with a variety of detectors, gas chromatographs, automated ion analysers, atomic absorption spectrophotometer, carbon analyser, and flow-injection nutrient analyzers. The new and spacious laboratories allow for bench scale testing of various process conditions in three controlled temperature environmental chambers. Present research addresses, among other: nutrient removal and recovery; removal of endocrine disrupting compounds; municipal solids and sludge utilization; optimization of water treatment processes; cold climate water and waste treatment and industrial waste processes.
