When dissolved Mn shows up in the source water prior to drinking water treatment, oxidation is a straightforward prescription.
What about "colloidal manganese"? This feature of the river water I'm trying to treat is apparently composed of tiny particles that pass through a 0.22 micron filter, do not change with KMnO4 oxidation, and are not reduced by the normal coagulation process (with Alum and polymer) and filtration (mixed media).
Academic research says it's a coagulation challenge, and the colloids have to be destabilized. I'm working on it, but not seeing much progress.
Has anybody faced this problem? Thanks!
