Use of Fe ( VI ) for Removal of Total Organic Carbons ( TOC ) and Heavy metals from Coproduced Water

The objective of the research is to develop a new, simple, and environmentally friendly method for the simultaneous removal of heavy metals and total organic carbon (TOC) in coproduced water (CW) from the energy production industry. Ferrate anions (FeO4) or Fe(VI) oxidation ability is very strong over the whole pH scale. Fe(VI) has been considered one of the futuregeneration water quality improvement agents. The oxidation of CWs TOC into CO2 and H2O can be done via Fe(VI). The result of the reduction of Fe(VI) is Fe(III) which is an excellent adsorbent for removal of heavy metals in CWs. Once the heavy metals and TOC have been removed from the CWs it is much easier to then remove the total dissolved solid (TDS) from the CWs. Water supply around the world is becoming insufficient for the growing populations and sources for additional water supplies must be established. Treated CWs can potentially be used to partly mitigate the tight water supply dilemmas in states such as Wyoming.
