For Zambia, the power consumption of the pumps for water abstraction, suction, distribution and treatment was the basis for determining energy required per hour. This energy was provided by biogas which was produced from a mixed feedstock of equal proportions made up of food leftovers, sewage sludge and fecal matter. This energy and amount of feedstock were used to design the biodigester. The model determined that a 1400m3 biodigester with biogas output of 8.6ML/day could yield 57kW electricity. These results compare proportionally very closely with those of the Safi Sana plant which has a 2500 m3 biodigester and produces 100kW electricity. For South Africa, energy requirements were modeled using experimental data obtained from water reclamation of wastewater and using sludge residue to produce biogas for electricity. This experimental model determined that 618ML/day of wastewater could be processed to yield power generation of 4.2MWh, an upscale from the current 97ML of wastewater per day that generates 1.1MWh.AbstractenBiogasBiodigesterMixed feedstockWastewaterArticleMwandila, G., Mwanza, M., Sikhwivhilu, K., Siame, J., Mutanga, S.
