Bioetp - Model BIO-200 -Biofilter system
Biofilter for waste gas streams containing VOCs and odorous compounds is more cost effective and environmental-friendly than conventional air pollution control technologies. In a biofilter, the pollutants are biologically degraded by aerobic microorganisms to stable end products like CO2, H2O, sulfate, microbial biomass, etc.In a biofilter, the pollutants are biologically degraded by aerobic microorganisms to stable end products like CO2, H2O, sulfate, microbial biomass, etc.
Biofilter has been proved its high efficiency to remove pollutants from gas exhausts, which are generated from livestock breeding and poultry raising industry, food processing industry and wastewater treatment plant. Its cost effective and simply maintenance makes the biofilter world-wide popular.
In a biofilter, the polluted gases pass through a bed of packing media covered with a layer of aerobic microorganisms. The pollutants are transferred from air into the biofilm where they are utilized by microbes as energy source. In the same time, the packing bed is continuously irrigated with an aqueous solution containing essential nutrients required by the bio-organisms.
1 Bio-trickling gilter
2 Humidification and nutrients liquid
3 Exhaust air loaded with odrous substances
4 Cleaned exhaust air
5 Media for biofilm growth
6 Biofilm with microbes
Pollutants in the polluted gas, finally will be degraded into non-harmful end-products: salt, water and dioxide.
Biofilters are suitable to treat waste air bio-degradable, and from a covered facility where it can be collected and directed, which generates from
