Ferox SM Chromium (Cr +6) Treatment (Lab.)
Recently completed bench-top treatability tests on the reduction of hexavalent chromium in groundwater and soils by our Ferox SM ZVI powder. The goal of the study was to derive field design parameters and dosage levels to reduce (Cr +6) contamination to its less toxic and soluble tri-valent (Cr+3) state. As shown in the photo, groundwater and soil from the site had an initial lime-green color due to the high concentrations of (Cr +6). The studies evaluated several dosages of Ferox SM powder in reducing the Cr +6 to Cr+3 within 30 days. As the Cr+3 precipitates out, the groundwater is treated. As shown, the color of the groundwater changed from lime-green to clear as Cr +6 was reduced.
