This study investigated water recovery with the treatment of leather industry processes wastewater (washing, pickling, and degreasing units) using coagulation, ultraviolet/persulfate (UV/PS) treatment, and nanofiltration processes. Coagulation studies were carried out using alum as the coagulant, and the...
