In water treatment mixing processes occur as rapid mixing (aiming the colloid destabilization by added coagulants), slow mixing (aiming the floc-aggregate formation) and mixing of disinfectans. The author focuses on the mixing processes of coagulation-flocculation. The intensity of mixing can be characterized by the mean velocity gradient, G (1).
