Sewage-Water Treatment and Sewage-Sludge Management with Power Production as Bioenergy with Carbon Capture System: A Review

Sewage-water treatment comprehends primary, secondary, and tertiary steps to produce reusable water after removing sewage contaminants. However, a sewage-water plant is typically power energy consumer produces high volumes of sludge mainly generated in the primary secondary steps. The use more efficient anaerobic digestion with can reasonable flowrates biogas, which shown be consolidated strategy towards self-sufficiency economic feasibility plants. Anaerobic also reduce carbon footprint sources since biogas produced replace fossil fuels for electricity generation. In summary, socio-economic importance high, this review examined works that contemplate: (i) improvements bioenergy production performances; (ii) exploitation technology alternatives plants; (iii) implementation new techniques sewage-sludge management aiming at production; (iv) capture storage.
