Moringa oleifera seed powder was taken as 1g, 2g, 4g, 6g, 8g, 10g as coagulant and tested in 500ml of water samples. Citrullus lanatus seed suspension was taken as 5ml, 10ml, 15ml, 20ml, 25ml as coagulant and tested in 500ml water sample. Finally we treated water with combination of moringa oleifera seeds and citrullus lanatus seed suspension in ratio of 1:1.
