Iron Removal By Slow Sand Filtration

Iron and manganese are unaesthetic parameters present mostly in groundwater, causing unwanted precipitation and coloriron 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 3iron removal by physicalchemical way consists in iron oxidation by air followed by sand filtration, but other techniques exist as well.
