The reactor includes a chamber typically listed below the ground. It has an inlet for inputs (primarily human excreta) and two electrical outlets (one at the centre for biogas, and the various blog here other on one of the sides for outlet of sludge). Enhancement of animal manure and vegetation will certainly boost the performance of the activator.
If adequate wastes are created, private households can each have one and get the advantage of biogas production. In bigger towns and cities, fluid waste might be shared by means of a sewerage network to a centralised wastewater therapy plant; for instance, Addis Ababa's waste is dealt with at the Kality Wastewater Therapy Center.
