Anaerobic digester types

The following is a partial list of different types of anaerobic digesters. These processes and systems harness anaerobic digestion for purposes such as sewage treatment and biogas generation.

Examples include:

• Anaerobic activated sludge process
• Anaerobic clarigester
• Anaerobic contact process
• Anaerobic expanded-bed reactor
• Anaerobic filter
• Anaerobic fluidised bed
• Anaerobic lagoon
• Anaerobic migrating blanket reactor
• Batch system anaerobic digester
• Continuous stirred-tank reactor (CSTR)
• Expanded granular sludge bed digestion (EGSB)
• Hybrid reactor
• Imhoff tank
• Internal circulation reactor (IC)
• One-stage anaerobic digester
• Submerged media anaerobic reactor
• Sintex Digester
• Two-stage anaerobic digester
• Upflow anaerobic sludge blanket digestion (UASB)
• Upflow and down-flow anaerobic attached growth
