Gerard B. Hawkins Summary of Residuals Generation, Treatment, and Disposal at Large Community Water Systems Iron Removal Strategies Iron, usually presents in groundwater as divalent ion (Fe 2+) and is considered as source of membrane scaling. In order to be eliminated, iron complexed requests a coagulation stage, which comes in between oxidation and filtration. The elimination of the ferrous iron, by physical-chemical way, is obtained by raising the water redox potential by oxidation thanks to oxygen of the air and this by simple ventilation. (Parallel installation means that the water flow is split so that half flows through one filter and half through the other.) The elimination of the ferrous iron, by physical-chemical way, is obtained by raising the water redox potential by oxidation thanks to oxygen of the air and this by simple ventilation. Usually groundwater has a low oxygen content, thus a low redox potential and low pH (5.5- 6.5). VGO-HDT process flow diagram 16.
