Abstract:

The Lakeview wastewater treatment plant (WWTP) in Mississauga, Ontario, is owned by the Region of Peel and is operated by the Ontario Clean Water Agency (OCWA). The plant has been equipped with fluid bed incineration (FBI) systems as its disposal option for almost thirty years. Due to the high maintenance and the odor generated by Zimpro, in 2003 the Region of Peel decided to eliminate the heat-treated system and to replace the three existing CWB fluid beds by four hot-windbox (HWB) fluid beds, each dispose of 110 US tons of dry sludge per day. The new system is equipped with external shell and tube heat exchanger for preheating the combustion air to 1230°F and a multiple venturi scrubber as air pollution control device. The system satisfied the design emission requirements by a wide margin upon performance testing. The paper discusses the transition period during the replacement of the Zimpro system.
