چکیده انگلیسی
Chemical Coagulation (CC) and Electrocoagulation (EC) processes using iron as coagulating agent were compared while treating aquifer water contaminated by a relatively high concentration of total chromium (CrTâ¯=â¯19.0â¯mgâ¯Lâ1). A continuous semi-pilot comprising of EC (or CC), followed by flocculation, sedimentation and sand-filtration steps was used to remove CrT from water in order to get drinking water. A ratio of Fe/CrTâ¯â¥â¯3 was required to reach the best efficiency of treatment using EC and CC. More than 99% of CrT was removed and residual CrT concentration below 0.05â¯mgâ¯Lâ1 (the limiting value recommended by WHO) could be obtained using the both configurations. However, CC increased the concentration of dissolved solids above the guideline recommended for drinking water.
