Odour Control Devices - Selection, Design and Application

Wastewater odours can cause offence and disruption to communities and property owners in close proximity to wastewater assets. This in turn can cause reputational risk to asset owners and vexatious technical issues to wastewater network operators and designers. 

This paper investigates a range of odour control devices as a tool to asset owners and designers alike for the purposes of controlling and mitigating wastewater odours. The means of appropriate technical selection of devices is considered along with a commentary on common misconceptions impacting device selection. The sizing of devices is considered, along with guidelines for the appropriate sizing for both effective odour treatment and optimised whole of life costs. 

A consideration of wider wastewater network issues is undertaken and a methodology for effectively integrating odour control devices into existing networks to facilitate effective odour solutions is given. The principles of Integrated Odour Management are highlighted and used to demonstrate effective methods of reducing hydrogen sulphide production and air flow management to in turn improve the effectiveness of odour treatment, and reduce the operating costs of odour devices employed on troublesome wastewater networks.
