An anaerobic digestion process will be installed for biogas production from an animal wastewater. The wastewater has a biodegradable COD concentration of 7000 and 5000mg/L VSS with 70% of the VSS biodegradable. Briefly critique the compatibility of the following anaerobic processes for conversion of the wastewater to biogas and describe the potential impact of the influent solids on the reactor operation and performance. Anaerobic processes:

• UASB reactor

• Anaerobic expanded-bed reactor

• Anaerobic baffled reactor

• Upflow APB reactor

• Covered anaerobic lagoon
