摘要：This study treated the waste valorisation of steel industrial wastewater (SIWW) rich of ferric chloride as an original coagulant for removal of landfill leachates. The study also compares the different dosage of SIWW with ferric chloride. Jar-test experiments were employed in order to determine the optimum condition for the removal of organic matter. The effect of different dosages of SIWW in contamination with classic coagulant was also studied. The results reveal that lower pH values less than 5 enhance removal efficiency of contaminants. The percentage removal of 56, 78.3 and 72% of COD, BOD5 and NTK respectively were achieved by addition to 7 ml/l SIWW. 54.4, 76.7 and 70% removal of COD, BOD5 and NTK respectively were achieved by addition to 1200 mg/l classic coagulant. The volume of sludge produced, was lower compared to classic coagulant.
