Table 4 Biogas production estimates for anaerobic digestion of algae biomass grown on wastewater nutrients

Description	Source	Algae biomass (tons yr^-1)	Biogas production (kg yr^-1)	Total energy (MJ yr^-1)	Households powered¹
Wastewater	HFC AWTP	1,965	123,215	6,776,838	144
Centrate	HFC AWTP	4,660	292,294	16,076,165	342
Total		6,625	415,509	22,853,003	486

¹ Assuming average energy consumption of 653 kWh per month and thermal efficiency of natural gas turbine of 60% with waste heat recovery.
