Canadian council looks to engineering firms for odour control

Lunenburg council, in Nova Scotia, Canada, is looking to engineering firms in an attempt to solve odour control problems.

The town's wastewater treatment plant has been plagued by odour problems since its opening in 2003 with the issue becoming particularly bad on humid and foggy nights.

The council has invested thousands in try to fix the problem in recent years and now it is drafting in the help from engineering companies.

Initial estimates have found that it could cost taxpayers in Lunenburg over $1 million to control odours which emanate from the town's wastewater treatment plant. After several sources were identified and various odour control systems were considered,

After identifying several potential sources of odour at the plant, then considering various odour control systems, a biofilter or photo-ionization were considered as solutions.

The first would use a phased-in approach which would begin with the installation of a biofilter for the headworks followed by the dewatered sludge storage bin, which would be located in the process room. A second phase could be needed to control odours from the sludge holding tank.

If both phases are deemed necessary, the total cost of the project would be $881,750 plus Harmonized Sales Tax (HST).
