| Pot
Perm is a strong oxidizing |
| agent.
It converts dissolved iron and/or |
| manganese
to insoluble oxides, which can |
| be
easily removed by filtration. Pro-Pot |
| Perm

| methods
of introducing permanganate to |
| the
filter, one method is to make a |
| solution
and apply automatically or |
| manually
at regular intervals. |
