Biofilters for odour control
Conventional Biofilter
- Biological treatment system
- Low operating costs
- Great footprint compared to other technologies
- Large spectrum of gaseous pollutants removed
- Specially indicated for low inlet concentrations of H2S and VOCs
- Requires a previous stage of air humidification or other pretreatment
- Continuous operation regime
- Sectors: urban and industrial wastewater treatment plants and MSW treatment plants
Biofilter packed with volcanic stone
- Durability of filter material far superior to conventional biofilter media
- Requires nutrient water supply (normally filtered secondary effluent, or chlorine-free tertiary effluent)
- Smaller footprint than conventional biofilter
- Does not require air pretreatment stage
- More robust system than conventional biofilters
- Mixed media bioreactors improve global odour abatement
- Continuous operation regime
- Sectors: urban and industrial wastewater treatment plants
