Mar 13, 2003 Manganese greensand is a specially processed medium for iron, manganese, and hydrogen sulphide removal.This premium non-proprietary filter medium is processed from glauconitic greensand on which a shiny, hard finite thickness manganese oxide coating is formed and is firmly attached on every grain by a controlled process.. In the years prior to World War II, researchers in the
Iron and manganese are unaesthetic parameters present mostly in groundwater, causing unwanted precipitation and color. Iron removal Iron removal is based on the precipitation of dissolved iron Fe 2 into its oxidized form Fe 3, as FeOH 3 or Fe 2 O 3.. Iron removal by physical-chemical way consists in iron oxidation by air followed by sand filtration, but other techniques exist as well
