Performance and optimization of an oxidation-filtration process for iron removal from groundwater in Morokro (Tiassalé, Côte d’Ivoire)

Over ۶۰% of the groundwater in the Tiassalé region contains iron concentrations exceeding the WHO guideline value (۰.۳ mg/L). Although iron is not a major health hazard at low doses, its excessive presence can degrade water quality and indicate the presence of other potentially harmful contaminants. This study aims to develop an effective treatment method for the deironization of groundwater in Morokro. A detailed physico-chemical characterization of borehole water samples was first conducted. A multi-criteria analysis was then employed to identify the most suitable treatment option, selecting the oxidation-filtration method. The optimization of this process Was conducted using a Box-Behnken experimental design. Optimal conditions for iron removal were obtained for an HCl concentration of ۱۵.۵۵۵ mg/L, an HCl dose of ۷.۳۲۳ mL, and an aeration time of ۵۰.۳ minutes. These findings led to the development of a tailored treatment protocol adapted to the specific characteristics of Morokro's groundwater.
