How does work biofiltration?

Biofiltration is a biotechnology that uses specific bacteria embedded in a biofilter bed to treat a contaminated gas-off. The pollutants are adsorbed into the bed and subsequently degraded by the microorganisms mainly to CO2 and H2O. Any oxides of nitrogen (NOx), particulate matter, sulfur dioxide (SO2), and carbon monoxide (CO) are generated. Biofilters are suitable to treat off-gas contaminated with VOCs (volatile organic compounds), undesired odours and some inorganic pollutants:

  • aromatic hydrocarbons (BTEX, styrene, etc)
  • alcohols (methanol, ethanol, etc.)
  • esters
  • aldehydes
  • ketones
  • amines
  • organic acids
  • mercaptans
  • ammonia
  • hydrogen sulfide
  • and other substances

Advantages

Biofiltration is economically more advantageous compared to the physical-chemical and chemical processes at the same efficiency. Unlike conventional technologies such as thermal and catalytic incineration, scrubbing or carbon adsorption, biofiltration is:

  • efficient (with full degradation of the contaminants)
  • environmental friendly & safe (transforming pollutants into harmless products, waste-free and no combustion sources)
  • cost-effective (low Capex and Opex)

Applications

Typically, biofilters are wide used in the following industries or sectors:

  • Food & Beverage
  • Biomass and biogas purification
  • Rendering and animal breeding
  • Oil and asphalt
  • Industrial Waste Water Treatment  & Waste Solid Treatment plants
  • Municipal Waste Water Treatment  & Waste Solid Treatment plants
  • Paint & Coating
  • Fiberglass production and plastic manufacturing
  • Paper & Printing
  • Pharmaceutical and cosmetic
  • Textile
  • Tobacco
