This study examines iron removal from synthetically prepared high iron concentration water using electrooxidation (EO), electrocoagulation (EC), and combined treatment. The effects of various process variables like applied voltage, salinity, and initial iron concentration were analyzed for EO and EC treatments. Results show that 100% removal of iron was obtained at pH 7, with applied voltage of 6 V, contact time of 6 h, and salinity of 0.5%. Combined EO–EC technique proved most cost effective amongst the above three treatments. For iron removal in high-salinity groundwater by these techniques, follow first-order kinetic model.

摘要

This study examines iron removal from synthetically prepared high iron concentration water using electrooxidation (EO), electrocoagulation (EC), and combined treatment. The effects of various process variables like applied voltage, salinity, and initial iron concentration were analyzed for EO and EC treatments. Results show that 100% removal of iron was obtained at pH 7, with applied voltage of 6 V, contact time of 6 h, and salinity of 0.5%. Combined EO–EC technique proved most cost effective amongst the above three treatments. For iron removal in high-salinity groundwater by these techniques, follow first-order kinetic model.
