Anaerobic Biotechnology for Sewage Sludge Treatment: Integrating Anaerobic Bioleaching with Anaerobic Digestion. KU Leuven
During wastewater treatment, a significant amount of sewage sludge (SS) is generated as a by-product, with an estimated production in Europe alone of 2 bio tons/yr. SS use as fertilizer and anaerobic digestion are 2 disposal routes that comply with current legislative guidelines on waste disposal and environment. Anaerobic digestion (AD) is widely applied, resulting in volume reduction and biogas production. However, high heavy metal (HM) ...
