Mechanism of red mud combined with steel slag conditioning for sewage sludge dewatering

Red mud (RM), which is a byproduct of alumina refining, is typically stored in landfills. This study investigated the capability of RM combined with steel slag to improve sludge dewatering performance. When the RM dosage was 20 mg/g, the HCl/RM ratio was 0.6, and the steel slag dosage was 3 mg/g DS,...
