The range of raw water zeta potential is reported to be between -10 and -20 mv, however I got the zeta value of -30 mv for a river water with high concentration of humic substances and calcium hardness.

Zeta potential is the charge at the boundary of the colloidal turbidity particle and the surrounding water. The higher the charge the more is the repulsion between the turbidity particles, less the coagulation, and vice versa. Higher zeta potential requires the higher coagulant dose. An effective coagulation is aimed at reducing zeta potential charge to almost 0.
