Effect of raw water quality on coagulant dosage and optimum pH

Removal of turbidity, suspended solids (SS) and natural organic matter (NOM) using coagulation are well known because of the ability of the process in destabilizing the colloids particles and reducing the repulsion force between the particles. The objectives of the study are to explore the effect of...
