The Biopuric Process is an unique combination of existing technologies, wherein sulfur oxidizing microorganisms in the biofilm metabolize hydrogen sulfide into elemental sulfur and sulfuric acid, thus purifying the biogas.

This proven, exclusive Biothane process is installed in municipal and industrial fields. Operating plants are effectively treating biogas with hydrogen sulfide concentrations ranging from 1,000 ppmv to 15,000 ppmv. Removal rates consistently range from 90 - 98%.

The process is environmentally safe and has minimal power requirements. Absence of harsh chemicals ensures that the waste products are not detrimental to the environment.

Benefits of the Biopuric™ technology include:

  • Low energy requirements
  • Little (if any) chemical usage
  • No hazardous chemicals to work with
  • Easy to operate and maintain
  • Proven track record of performance
