Oxidation of Iron and Manganese

Calculate the amount of air needed to be supplied to the water to oxidize all the iron and manganese in the source water

TABLE FOR CALCULATION OF OXYGEN DOSAGE REQUIRED TO OXIDATE IRON AND MANGANESE

Input

Input Data Unit
Iron concentration mg/l or ppm
Manganese concentration mg/l or ppm
Flowrate m3/h
An accepted value of residual oxygen for other oxidation mg/l or ppm
The oxygen transfer efficiency of aeration devices From a low end of 5% to a high end of 25% to 35% for Mazzei Injectors. Using a figure of 25% for Mazzei Injectors is conservative and is supported by both laboratory and field data. %
