MANAGING ODOUR PROBLEMS FROM THE PEEL REGION LAKEVIEW WWTP THROUGH PROCESS CHANGE AND PUBLIC COMMUNICATION MAKES CLEAR SCENTS
Abstract:The Lakeview WWTP provides 392,000 m3/d conventional activated sludge treatment capacity. Wastewater sludge is processed through thermal conditioning, vacuum filter dewatering and incineration in fluidized bed incinerators. The plant has had a history of odour problems. In order to address the odour problems, the owner, the Regional Municipality of Peel, initiated the Clear Scents odour management strategy. This strategy included odour collection and treatment, sludge process upgrades and public consultation and communication, aimed at minimizing the impacts of plant odours on the community. The Region's short-term odour management strategy consisted of: containment, collection and destruction of odours from major point sources; elimination of a capacity bottleneck in biosolids processing, which has been the cause of sludge accumulation and odour generation from the wastewater treatment tanks; phasing out a portion of the thermal conditioning process, which reduced the high strength odours generated from this process, and the recycle of odorous waste streams from the sludge processing facility to the wastewater treatment plant; and, adding odour control chemicals at key points in the collection system. Concurrent with the implementation of technical measures, the Region implemented a multi-dimensional strategy for communicating and consulting with the public.
