Ferrous chloride (FeCl2) added to chromium-laden brines produced by strong base anion exchange (SBA-IX) systems reduces hexavalent chromium [Cr(VI)] to trivalent chromium [Cr(III)] and precipitates the Cr(III) in a mixed chromium-iron hydroxide solid solution. A series of jar tests was conducted in which FeCl2 was added to synthetic SBA-IX brines. The variables investigated were initial Cr(VI) concentration, initial pH, and Fe(II):Cr(VI) stoichiometric dose ratio. This reduction-coagulation-flocculation (RCF) process was also tested on field brines with various compositions. The RCF process achieved greater than 77% chromium removal efficiency at all tested conditions, except in brines with a bicarbonate matrix. Significant vanadium and arsenic removal (>78% and >49% removal, respectively) was observed in field brines with a chloride or sulfate matrix. Diffuse double layer modeling suggests that adsorption to the precipitated solids was the predominant removal mechanism of vanadium and arsenic.
