Leachate refers to the meteoric waters that seep through the landfill with pollutants that are both mineral and organic. Physical chemical treatments can be considered alone, or in a treatment compared to a biological treatment.

The process of flocculation of coagulation with lime as coagulant and ferric chloride as flocculent has been optimized for removal. The optimization technique is done using the composite response method 42 central and surface. The effect of the three factors (pH, coagulant dose and flocculent volume) for the elimination of the organic load and in suspension was studied and revealed positive.

Optimal conditions achieved by compromising desirable responses such as SS removal, turbidity removal, COD removal and Se elimination represented 15 g/L of coagulant assay, 2.5 g/L flocculent dosage at pH 10.5 The maximum removal of SS, COD, Turbidity and Conductivity in …
