Outline

• Biofiltration Technologies
• H2S Emissions Control
• VOC Emissions Control
• NOx Emissions Control

3
Biofiltration

• Utilization of Natural Materials and
  Microorganisms Growing in a Media Bed to Destroy
  Organic Compounds and Remove Air Toxics from an
  Air Stream
• Addition of Biomass Support Media (Wood or other
  packing) improves biofilter performance through
  reduced pressure drop and improved air flow and
  contaminant distribution

4
Biofiltration Technology for Air Pollution Control

• Very Moderate Initial Capital Costs
• Low Operating Costs
• Generates non-hazardous by-products
• Treatment to handle wide range of VOCs
• Consortium of microorganisms, once well developed
  can handle moderate fluctuations in input gas
