Abstract

This study investigates the effect of suspended matter concentration on the coagulation-flocculation and decantation treatment process of a low brackish water C(NaCl) = 1 g/L aiming for an effective optimization of the process using slightly brackish and turbid waters. Experiments were performed to detect the optimum performance of coagulant (Al₂(SO₄)₃) and flocculant on pH and turbidity removal from different bentonite solutions (0.5, 1, 1.5 and 2 g/L). The effects of coagulant dose, flocculant dose, decantation type, feed rate, speed, and time of rapid and slow mixing are also investigated. The medium mixing speed and the co-current lamellar decantation were adequate to improve turbidity removal to high efficiency (99.84%). Using a TE 600 pilot plant to test the optimum experimental conditions resulting from batch experiments, showed a high yield of turbidity removal confirming an application possibility of these experimental conditions in a real treatment plant.
