Trevi’s BEtOfilter

Principle

A humidified waste gas is blown through a reactor which is filled with an organic carrier material. On the surface of this carrier, a 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 very high gas flow, e.g. aeration room air flows (up to 50,000 cfm).
