Biofiltration Systems
Odours and organic emissions are an inherent part of wastewater treatment and industrial processes. Biofiltration has been in use in Europe since the 1950's and is now recognised worldwide as a highly efficient and cost effective air pollution control technology.
How do biofilters work?
The biofilter process relies on the principles of microbial oxidation, whereby microbes oxidise the odours and offensive organics, using them as a food source and converting them into non-odorous carbon dioxide and water vapour. In the case of hydrogen sulphide, a sulphate salt is formed and retained in the bed.
Biofiltration system features
- Ability to treat several contaminants simultaneously
- No chemical requirement
- Renewable, sustainable technology
- Simple to operate
- Odour removal efficiency greater than 95% in most cases
- Treated air dispersal over wide area
- Effective lifespan of media is 5 years

Contaminated air is distributed and passed through the moist organic media. Within the bed, contaminants are absorbed into the water layer surrounding the media surface where they are biologically destroyed by active bacteria.
