Drinking water was also reclaimed as part of the treatment process, hence rendering this system a zero-liquid-discharge (ZLD) process. For the synthesis of goethite, hematite, and magnetite, Fe(III) and Fe(II) were recovered via sequential precipitation in batch reactors. Lime was added to treated water to synthesize high-grade gypsum.
