Groundwater is presently one of the major sources of water supply in Kelantan. The problems with iron in water are mainly aesthetic. Iron gives water a sour, metal taste, stains laundry, and food cooked in the water receives an unappetizing colour. This research is focused on removal of iron and manganese from groundwater. The area of focus was mainly the Chicha Kelantan Groundwater plant. The removal of ferrous iron (Fe (II)) and Mn in groundwater has been generally achieved by simple aeration, or the addition of an oxidizing agent or the lime treatment. Aeration has been shown to be very efficient in insolubilization of ferrous iron at a pH level greater than 6.5 and maintaining iron concentration 0.3 mg/1. Also it is effective for maintaining concentration of 0.05 mg/1 for manganese. In this study, some of the removal methods were experimented in the Chicha and in UTP such as aeration and coagulation with all complete results attached. It can be concluded that coagulation, flocculation after aeration further decrease the Fe and Mn concentrations in the water. Concentrations of Fe are low as 0.02 mg/1 and for Mn are 0.035 mg/1 which is a tremendous result. Although lime is not recommended, sodium hypochlorite might be an ideal replacement for other chemical additions. After hypo addition, concentrations of Fe are 7.95 mg/1 and Mn is 13.2 mg/l considering very high dosage of Fe & Mn solution. It is effective to reduce both Fe & Mn concentrations.
