Oxidation Reduction behaviour is highly contributes to the condition of the water. Oxidation reduction potential [ORP] gives an idea about the Redox behaviour of water while the pH value give an indication about the behaviour of the Hydrogen ion concentration. When Manganese is in water, it can exist either as particulate matter or as dissolved matter and this can be showed in Manganese phase diagrams. Due to the inconvenient consequences, Manganese should be removed from the water if only it has a higher concentration. For this, oxidation can be done by using Calcium hypochlorite and the obtained precipitate can be filtered. The behaviour of different Manganese species fluctuates with different pH values and Eh values. The objective of this study was to determine the effect of pH and Eh while changing the different concentration of Calcium hypochlorite to the blended Manganese solution which is prepared by using MnSO4. Final concentration of Manganese was reduced with lower concentration of Calcium hypochlorite and ORP values were reduced with the increasing pH. To conclude the result, Mn3O4, Hausmannite was obtain as the Manganese species according to the Manganese phase diagram.
