Theoretical stoichiometric calculation for Fe2+ and Mn 2+ removal using KMnO 4 A groundwater containing 5 g/m 3 Fe 2+ and 2 g/m3 Mn2+ is processed at a flow rate of 100,000 m 3 /d. Potassium permanganate (KMnO 4 ) is used to oxidize the Fe 2+ and Mn 2+ . Calculate the quantity of potassium permanganate required, alkalinity consumed as CaCO 3 , and quantity of sludge produced. Use the oxidation reactions for iron and manganese using KMnO4 as shown in Tables 20-8 and 20-10, respectively.
