Water Treatment: Aluminum Sulfate, Polymer, and Activated Carbon Between Efficacy and Overdosing. Case of Oum Er-Rbia River, Morocco

This article examines the impact of aluminum sulfate, polymer, and activated carbon on water treatment processes. General observations indicate that aluminum sulfate effectively reduces turbidity, but excessive use can result in reagent wastage. Similarly, polymer addition reduces turbidity up to an optimal dosage, beyond which it may contribute to increased turbidity and the same thing for activated carbon. The study emphasizes the significance of conducting jar tests to optimize the quantities of these chemicals through design of experiments (DOE), aiming to improve treatment effectiveness in order to meet international requirements in term of turbidity norms while reducing costs. By achieving the right balance, water treatment processes can efficiently remove suspended solids, leading to improved water clarity.
