As neighbouring areas continue to encroach upon wastewater treatment plants, there is an increasing need for odour control to mitigate potential negative offsite odorous impacts. One technology that is gaining widespread acceptance is biotechnology which utilises the inherent ability of certain micro-organisms to biodegrade offensive odorous compounds. Two main advantages of this form of treatment over other odour control technologies include absence of hazardous chemicals and relatively low operation and maintenance requirements

The purpose of this paper is to provide information related to odour control design criteria used in sizing/selecting biotechnology-based odour control technologies and provide odour removal performance data obtained from several different biotechnology-based odour control systems.

CH2M HILL has collected biotechnology-based odour control performance data over the last several years in order to track continued performance of various biofilters and biotowers over time. Specifically, odour removal performance data have been collected from soil-, organic- and inorganic-media biofilters and inert inorganic media biotowers. Results indicate that biotechnology-based odour control is a viable and consistent technology capable of achieving high removal performance for odour and hydrogen sulphide.

It is anticipated that the information presented in this paper will be of interest to anyone involved with odour control technology evaluation/selection or design review.
