The use of a submerged membrane batch reactor (S.M.B.R) for co-treatment of landfill leachates and domestic wastewater

A B S T R A C TThe efficiency of Fenton reagent (Fe 2+ + H 2 O 2 +H + ) for the leachate generated from Pulau Burung sanitary landfill site, located in Malaysia, was evaluated with the objectives of chemical oxygen demand (COD), apparent color, and turbidity reductions. Response surface methodology was used to study the effect of hydrogen peroxide (as oxidant) and ferrous sulfate (as catalyst) on COD, apparent colour, and turbidity reductions of sanitary landfill leachate. A central composite design in two factors [hydrogen peroxide dosage (mg/L) and ferrous sulfate dosage (g/L)] was employed to build a model as well as to perform optimization of the Fenton process. The optimum results for COD, apparent color, and turbidity reductions were 68, 81, and 86%, respectively, setting [H 2 O 2 ] at 747.8 mg/L and [FeSO 4 ] at 12.8 g/L.
