Description

Moderate-rate, complete-mix, anaerobic digestion process.
This proven technology maximizes contact between the anaerobic biomass and degradable organics, making it a good choice for digesting difficult-to-treat waste streams with high concentrations of solids, and fat, oil, and grease (FOG). Additionally, primary sludge or waste activated sludge can be digested in the ADI® CSTR to further increase biogas production.

A solids separation stage can be used to decouple the hydraulic and solids retention times, which can result in increased biogas production and stability. The CSTR can be paired with a membrane barrier, resulting in the cutting-edge ADI® anaerobic membrane bioreactor (AnMBR) system that maximizes biogas production and generates the highest possible quality anaerobic effluent.

  • Digests the most difficult-to-treat wastewater and slurry streams
  • Consistent operation during variations in influent feedstock characteristics
  • Solids recycle for increased biogas production and stability
  • Easily upgraded to an AnMBR system
  • Recover energy from biogas to reduce plant’s fossil fuel usage
