From Waste to Resource: A Circular Economy Approach for Landfill Leachate Treatment Using Coal Gangue-Based Coagulant and Beneficial Reuse of the Generated Sludge
This study explored the utilization of coal gangue with high iron content to synthesize poly-ferric-alum-sulfate (PAFS) and coal gangue leaching residue-PAFS (CG@PAFS) coagulants, which were subsequently applied to treat landfill leachate and its concentrate. The results demonstrated that the PAFS coagulant exhibited n...
