This study aims to valorize Chouara Tannery's water sources (the Boukhrareb creek and local underground water) by eliminating some typical pollutants using coagulation-flocculation process followed by activated carbon filtration. For the coagulation-flocculation process, we used ferric chloride (FeCl3) and aluminum sulfate (Al2(SO4)3) separately with different dosages to choose the most efficient coagulant. According to the experiment results, analyzed pollutants, heavy metals, and turbidity were well decreased by (FeCl3) with an optimal concentration of 15 mg/L for Boukhrareb creek and 20 mg/L for underground water. In particular, turbidity was reduced with coagulation- flocculation process; it has reached 0.27 NTU for Boukhrareb creek, as well as 1.8 NTU for local underground water after activating carbon filtration. In addition, some toxic heavy metals such as iron, phosphorus, and aluminum were removed up to 99% and mercury for 100% for both water samples. For this reason, this research strongly suggests using ferric chloride as a coagulant-flocculant followed by activated carbon filtration before using them in Chouara Tannery leather production's process.
