Managanese Removal Systems
To remove manganese from water with a filter, a high pH reading and a sufficient oxygen content are necessary to ensure precipitation. Although different filter media have different requirements, in most cases a pH greater than 8 is need for effective manganese removal. In most cases, an oxidizer like chlorine, air, ozone, or potassium permanganate is used as a pretreatment to filtration. Amendment of pH is also often needed.
Removal of manganese with a filter can vary from very simple, with any good granular medium, to a much more complicated two or three step process which requires adding an oxidizer and a pH amendment step.
