Design, Commissioning and Operation of the Odor Control Systems for the Pine Creek Wastewater Treatment Plant

An award winning, state-of-the-art Biological Nutrient Removal (BNR) Wastewater Treatment Plant (WWTP) was built in the south of the City of Calgary, surrounded by new residential developments. Odor control was a major commitment and a complete odor emission characterization study was carried out. Odor dispersion was modeled and four different systems were designed, three biofilters and one caustic scrubber. A prequalification process took place to select the biofilter vendor (BioRem). The systems have been built and are currently operating. Several issues were encountered during commissioning and operation but after resolving issues, a series of Guaranteed Performance tests proved the effectiveness of the systems. No odor complaints have been received after a year of operation.
