At PFWA, under our brand OdaTech®, we design and supply a comprehensive range of highly efficient and cost effective systems for the treatment and elimination of intrusive odours.

Initially developed for use in wastewater, our custom designed systems can be configured to suit a wide range of applications – from small air valves and manholes, to waste water
treatment plants, meat processing plants and mining sites.
Our systems achieve over 99% removal of hydrogen sulphide (H2S) and significantly reduce corrosion on steel and concrete infrastructure, most notably in sewer networks, drastically reducing costly maintenance. Additionally, we design and manufacture a range of chemical wet scrubbers for the effective removal of potentially dangerous contaminants in gas streams

Odour Treatment

Odatech® produces a comprehensive range of engineered, highly efficient and cost-effective odour control systems specifically designed and developed for odour removal and corrosion prevention for municipal and industrial applications.


The root cause of odours and corrosion in sewer collection systems is sulphide generation by bacteria in waste water passing through sewer pipes and infrastructure.

Odatech Products

OdaTech® offers odour control systems with very low life cycle costs for both above and below-ground applications and for treating varying gas flow volumes and odour concentrations.

System Features

OdaTech® products fully comply with WSA 121-2004 Industry Standard for Biofilters for Odour Control.
