Iron & manganese oxidation

Indicative calculation of theoretical oxidant demand (hypochlorite, permanganate, chlorine, chlorine dioxide or air) for removing Fe and Mn from raw water given in mg/l and flow.

Iron & manganese oxidation

This calculator provides an indicative, theoretical oxidant demand (hypochlorite, permanganate, chlorine, chlorine dioxide or air) for removing iron and manganese from raw water. It is based on stoichiometric redox reactions; real doses must always be confirmed by jar tests or operation.
