Biofilter for Ethylene Oxide
The eco-friendly solution for low Ethylene Oxide (EtO) concentrations and high to very high airflows. Converts EtO into CO₂ and H₂O at ambient temperature, without chemicals or natural gas. Ideal for room air vents or aeration room vents.
Built for high airflows
Treats airflows up to 85.000 m³/h (50,000 cfm) with up to 200 ppmv EtO.
No chemicals or natural gas
An eco-friendly technique with harmless by-products: water and CO₂.
Very low operating costs
Fully automated, with low maintenance needs.
Trevi’s Biofilter - bEtOfilter
Principle
A humidified airflow is blown through a reactor which is filled with an organic carrier material. On the surface of this carrier, a selected microbial community is growing, degrading the organic compounds in the waste gas and converting the EtO into CO₂, H₂O and new biomass. The BEtOfilter operates at ambient temperature, without the need for chemicals or natural gas.
Application
- Waste gases with low EtO concentrations, up to 200 ppmv.
- Waste gases with hight to very high gas flow, e.g. aeration room air flows.
