Iron & manganese removal helper

Decision-tree assistant for tuning oxidant dose and filter operation when removing iron and manganese.

This tool does not do numerical calculations. It guides the operator through a decision tree. Choose the current situation behind the filter and follow the recommended actions. Values are based on operational experience; always combine them with lab data and local rules.

If chlorates are an issue, switch the oxidant to permanganate.

Sodium hypochlorite (free chlorine)

Potassium permanganate (pink colour)

Is iron concentration behind the filter higher than 0.05 mg/L?
