Factors that can affect the biogas production

Rate and efficiency of the AD process is controlled by:
  • Type of waste being digested (co-digestion)
    • Pre-treatment
  • Process temperature
    • Mesophilic, thermophilic
  • pH and alkalinity
  • Hydraulic retention time
    • 10-12 days thermophilic, 15 - 20 days mesophilic
  • Organic loading rate
    • 2-3 g VS/l reactor and day
  • Inhibition and toxicity
