Effect of Interstage Hydrothermal Treatment on Anaerobic Digestion of Sewage Sludge: Speciation Evolution of Phosphorus, Iron, and Sulfur

Anaerobic digestion (AD) with interstage hydrothermal treatment (HT) (i.e., AD–HT–AD) is an emerging technology for energy and nutrient recovery from sewage sludge. Yet, systematic understanding on...
