Adding oxygen to remove dissolved gases in water , to oxidized and convert undesirable substances (i.e Iron and Manganese ) to a more manageable form.
4Fe2+ + O2 + 10H2O → 4Fe(OH)3 ↓ + 8H+
2Mn2+ + O2 + 2H2O → 2MnO2 ↓ + 4H+
these reaction may be happened in this stage where both ferrous iron and manganese are oxidized forming a non-soluble substances and removed after aeration.
