The objective of this work was to optimize electrocoagulation treatment parameters for the removal of colloidal suspension in dam water, reducing the cost and improving the quality of the treatment. For this purpose, we studied the impact of optimizing the volume of treated water and the agitation speed on the efficiency of electrocoagulation treatment of synthetic water simulating surface water. After the optimization of these parameters, we proceeded to apply it on the waters of the Sidi Said Ben Mâachou dam. The electrocoagulation test was realized in a batch reactor with two flat, parallel aluminum electrodes powered by a direct voltage of 12 V DC voltage. The ions released by electrolysis are stirred using a mechanical stirrer with flat blades. Performance monitoring was carried out using the following parameters: pH, conductivity, turbidity. The analysis of the various monitoring parameters showed that the performance of electrocoagulation is affected by the factors studied. The results obtained showed that intensive agitation of the solution leads to the destruction of the flocs, which subsequently minimizes the efficiency of the treatment.
