For reducing Mn and Fe without chemical must use big aeration, the air capacity is depend on the content of Mn&Fe value.
The trace ions Mn&Mn can be sent to the slow gravity Manganese Green Sand. The result of these ions must be < 0.01 ppm. For regenerate Manganese green sand you can use Na0Cl at pH 5.0-6.5.
