But when this water contains impurities like iron, turbidity, it impacts on water consumption. The objectives of this study were removal of iron and turbidity by using coagulation, sedimentation, jar test and filtration. Dolichos lablab, Litchi chinensis were used as natural coagulant and alum was used as chemical coagulant. Turbidity was removed by Litchi chinensis (88%) which was better than of Dolichos lablab (48%). But chemical coagulant alum (98.4%) was more successful than natural coagulants. pH was differed for Dolichos lablab (8.36) and Litchi chinensis (8.16) due to addition of alum in the treatment process. Salinity (359.13mg/l) was unaffected throughout the whole experiment. EC (406.2µS/cm) and TDS (201.99g/l) were decreased for natural coagulants `and increased (466.23µS/cm, 232.99g/l) for chemical coagulant. Initial value of Iron was measured 2.19mg/l. Both natural and chemical coagulant were successfully removed Iron up to 97.17%. All the analyzed parameters were compared with national and international drinking water quality standards to understand treated water quality. All of the physicochemical parameters of samples were in acceptable limits. The study recommended that, treated water could be used for drinking and domestic purposes.
