The effects of alum and glutinous rice flour as dual coagulant on the removals of colour and suspended solid from stabilized leachate were investigated. A series of jar test were conducted by optimizing the dose and pH of single coagulant (alum and glutinous rice flour) and its combination. It was observed that low removals (colour: 46%, suspended solid: 16%) were recorded by glutinous rice as single coagulant at pH 7 and dose 1.2 g/L. However, addition of glutinous rice flour (0.12 g/L) as coagulant aid for alum at pH 6 and dose of alum 2.5g/L, show better removals of colour (86%) and suspended solid (92%) from alum. At same pH and dose of alum as single coagulant, the removals achieved only 79% and 83% of colour and suspended solid, respectively. Thus, addition of glutinous rice flour as coagulant aid improved the colour and suspended solid removals from the stabilized leachate
