The removal of iron has always been accomplished by means of an oxidation reaction followed by the precipitation of ferric hydroxide. This study was performed to determine if precipitation of something other than ferric hydroxide would be feasible for such removal in a water‐treatment plant. The study determined that precipitation of ferrous carbonate may occur in many plants that treat hard water.
