PROJECT: DAWSON AERATED LAGOON PILOT PLANT
 LOCATION: City of Dawson, Yukon
OWNER: City of Dawson
DESCRIPTION: The 73 L/d thermally insulated pilot plant consists of two aerated cells each with a 15 day retention and a third cell with a 60 day retention. The objectives of the pilot program is to assess the ability of an aerated lagoon to treat a low temperature, low strength wastewater in order to produce an effluent that is non acutely toxic to fish by removing ammonia and surfactants from the wastewater. Heating and cooling loops were installed in each tank to control tank temperature.
ROLE: Design of pilot plant, procurement of equipment, development of testing program & operating procedures, overview of installation and operation and reporting.
