About OdourTeQ® Biological Filters

The OdourTeQ® range of BioTrickling Filters and Biofilters is built on the foundation of our in depth knowledge of immobilised bacterial fixed film technology. CleanTeQ has lead the development and implementation of the technology in many applications over the past 20 years.

The OdourTeQ® process uses the natural ability of selected bacteria to remove problem pollutants in air emissions.

Our biological approach to air pollution control provides the most cost effective means of odour and VOC abatement and minimises the environmental impact when compared to traditional chemical and adsorption methods.

The OdourTeQ® technology can be used to control emissions from industries such as food, manufacturing, chemical, solvent using, fertiliser and waste water treatment facilities.

Systems are available to treat air flows from as low as 200m3/h up to greater than 100,000m3/h with H2S concentrations ranging from 5ppm to in excess of 1000ppm.

OdourTeQ® BioTrickling Filters are extensively used for the treatment of sewer gas and emissions from waste water treatment plants. The unique design allows for the treatment of hydrogen sulphide and associated odorous compounds including reduced organic sulphides, VOCs, indols and skatoles in a single vessel. The process converts the pollutants to harmless salts, carbon dioxide and water providing greater than 99% removal of hydrogen sulphide and odour.
