drinking Water treatment: iron removal

and demonstrates that solubility rises as pH and TAC decreaseNote 1: when the dissolved iron concentration remains above that theoretical value, instead of precipitating the excess Fe 2+ in the form of FeCO 3 (siderite), one should suspect the presence of chelated iron, a source of difficulty when applying physical-chemical treatment for iron removal.
