On most sites Manganese will be reduced by the aerating iron removal filters. Where tests indicate that this may not be achieved MG filters are used. Usually, they are installed as a second stage polishing filter but can also be used as ‘stand alone’ filters removing both Iron and Manganese.
MG filters use a process called oxidation to remove iron and manganese from water. Not to be confused with aeration (which uses the available oxygen within the atmosphere) they require a stronger oxidant. This can be potassium permanganate or, where circumstances make possible, sodium hypochlorite.
We refer to these filters as ‘regenerating’ filters. The filter media can remove a certain amount of iron and manganese before it must regenerate. This process is fully automatic and doesn’t add anything to the treated water. Unlike ion exchange systems which swap iron and manganese for sodium.
There are theoretical calculations that govern how an MG filter performs but individual site conditions will dictate the final performance figures.
