Synopsis

This study investigated the application of chemical coagulation for treating leachate generated at the Magtaa Kheira’s landfill (Algeria). The effectiveness of the treatment and the influence of various factors (coagulant concentration (Al₂(SO₄)₃), pH, and stirring speed) on turbidity removal were optimized using response surface methodology (RSM) with a Box Behnken design. By analyzing the results, the optimal conditions predicted by the quadratic model were 1.3 g/L Al2SO4 at pH 5.3, achieving a removal efficiency of 94% turbidity
