3.1 The Process Parameters

To ensure optimal biogas production from human waste, several parameters and their impact on the anaerobic digestion process should be understood and will be briefly introduced in the following chapter:

• Temperature
• C:N Ratio
• Total Solids (TS)
• Volatile Solids (VS)
• Chemical Oxygen Demand (COD)
• Biochemical Oxygen Demand (BOD)
• pH
• Organic Loading Rate (OLR)
• Hydraulic Retention Time (HRT)
• Solid Retention Time (SRT)
