Dual coagulant has the potential to improve the coagulation process. In leachate treatment coagulation/flocculation can be used as a main treatment method or as a polishing/tertiary treatment step. Application of natural coagulant as coagulant aids able to increase the formation of floc and the removal ability of the coagulation process. This study was focusing on the ability of dual coagulants made from chemical coagulant (Alum) and natural coagulant (Cicer Arietinum (CA)) in removing colour from leachate. Jar test was carried out to investigate the effect of dose and pH on the removal ability of the dual coagulant. The optimum pH and dose for dual coagulant were obtained at pH 6.0 with dose of Alum at 4 g/L and dose of CA at 0.6 g/L with 94% removal of colour. While the optimum removal of colour for single Alum (4 g/L) and single CA (1.4 g/L) were recorded as 88% and 22%, respectively. The removals obtained using single natural and chemical coagulants were not as good as those obtained by dual coagulant. Thus, addition of CA as a coagulant aid for alum, able to increase the removal of color from leachate and has the potential to be applied as a treatment method for leachate.
