Bioleaching Process of Sewage Sludge and Anaerobically Digested Sludge via Indigenous Sulfur-Oxidizing Bacteria to Improve Dewaterability and Reduce Heavy Metal Content

Bioleaching Process of Sewage Sludge and Anaerobically Digested Sludge via Indigenous Sulfur-Oxidizing Bacteria to Improve Dewaterability and Reduce Heavy Metal Content

This study investigated the role of indigenous inoculum (primarily sulfur-oxidizing <i>Acidithiobacillus thiooxidans</i> and other acidophilic bacteria) in heavy metal removal from sewage sludge (SS) and anaerobic digested sludge (ADS). Four treatments were evaluated: inoculum + elementa...
