Brim is used to remove dissolved iron and manganese. The Ph must be above 6.8 and dissolved oxygen content must be equal to 15% of the iron and manganese content. No regeneration is required only periodic backwashing.
In this section you will find filtration media for the reduction of iron and hydrogen sulfide (rotten egg smell) . Manganese greensand is the single best method for removing these contaminants in higher concentrations and when other filter media will not quite work. Manganese greensand is regenerated with potassium permanganate.
