Odor Control - The Green Solution to Air Pollution

Columbus, OH BiofiltAer - 25,000 cfm

BiofiltAer allows naturally-occurring microorganisms grown in an environmentally controlled filter media bed to break down and eliminate malodorous compounds in an environmentally friendly process, with little if any affects from ambient temperature variations.

BiofitAer is available is several configurations, from small modular designs to large static pile systems. Below are some Biofilter configurations. Click on the images to enlarge them.

Unlike synthetic media based systems, the TPS natural media based system requires little or no additional nutrients (N, P, K) micro nutrients (Mn, S, Se), or buffering chemicals which add to the annual operations cost and complexity. Additionally, periodic loss of the emission stream does not result in a significant loss of biomass because of its backup food source supply contained within the media. Once the airstream is reintroduced, provided it is properly humidified, there is little if any additional re-acclimation time required.

Advantages of Biofilters

Lower operating costs than all competing methods such as chemical scrubbing, activated carbon, thermal oxidation and many other proprietary media systems.

  • Low capital costs.
  • Truly green process - no harmful chemicals used, low energy requirements and final products are inert.
  • Safe and reliable operation.
  • Long filter life (from 3 to 8 years).
  • Short and simple start-up.
