Bioventing for fugitive emissions

A whiff of change is in the air for low-volume odour as gas streams, thanks to OdaTech’s reinvention of traditional biofiltration systems. By Garth Lamb.

Offensive odours are one of the most frequently reported environmental pollution incidents, with the nation’s regulatory authorities fielding an increasing number of irate calls as communities sprawl out from major cities into land traditionally buffered from intense public scrutiny.

While there are a number of options for treating high flows of odorous gases from sites such as abattoirs, industrial facilities or wastewater treatment plants, Ivan de Souza points out that it is not just major plants that “create a nuisance for people who live around them”.

Currently with the asset management division of WA’s Water Corporation, de Souza has developed a biofiltration system to treat odours throughout the sewage collection system, particularly at venting stacks and pumping stations. After 33 years with the water authority, he is moving on to set up OdaTech, which will target not only wastewater systems but also industrial odour sources.
