Living downwind of a wastewater treatment plant or settling pond can be a fragrant experience. Natural bacteria break down sewage, but before they finish the job, neighbors often cry “Foul!” Geomembrane Technologies Inc. (GTI), a Canadian company that custom designs and fabricates cover systems, recently installed covers for two 65-foot-diameter wastewater settling tanks near Columbus, Ohio. The cover system allows treatment plants to collect biogas for re-use and improve odor control.
GTI, located in Fredericton, New Brunswick, Canada, specializes in covers for municipal and industrial wastewater treatment plants and drinking water supplies. Projects have included floating, modular, suspended, structurally supported, and gas-handling cover systems.
