BioFilters work by passing the waste air stream through organic filter media known as "BioFiltaire" with a "biofilm" containing bacteria that degrade the odour compounds. The "biofilm" is capable of degrading carbon, sulphur or nitrogen containing compounds, particularly to achieve high efficiency removal of low-level odorous pollutants.
Clean TeQ BioFilter systems can be used individually or in combination with other technologies to treat polluted airflows from 200 m3/h up to 100,000 m3/h and greater.
Clean TeQ® BioFilter design is based on:
- Practical Experience in similar applications
- Use of the CleanBioTM proprietary modeling program to enable the effects of different odor types, peaks and mixtures to be understood
- Media life
Other features include:
- Closed housing to maintain moisture levels independent of external weather conditions
- Automatic control of bed moisture through timers or moisture probes
- Use of specialised IIBioFiltaireTM " media for high performance and long life
- Use of Clean TeQ BioFilter Flooring system
Two types of BioFilter systems are available for pollutant treatment:
- Bacterial (Odor/Toxic control)
- Fungal (VOC control)
All Clean TeQ systems are designed using enclosed construction techniques to provide cost-effective and guaranteed treatment of pollutants.
Materials of construction are based on corrosion- resistant materials including FRP and corrosion- protected concrete.
BioFilter systems can also be supplied on design package/component supply basis (as above) if customer wishes to undertake construction components of project to reduce cost.
Clean TeQ® BioFilters can be used to control polluted air from a range of industries, including:
- Sewerage treatment plants
- Petrochemical industry
- Resin manufacturers
- Plastic industry (Extrusion)
- Chemical industry
- Food processing
- Rendering Plants
- Cost effective
- Small space requirement
- Natural process
- No chemical inputs
- No secondary pollution
- Low operating costs/Energy efficient
- Modular system
- Turn-key operation
- 90 to 99% + removal of odour
- 80% to 99% efficiency of VOCs and toxics e.g. hydrogen sulphide
