But humic ,acid, was removed only by charge ,neutralization, and adsorption bridging in the coagulation experiment. Therefore, the effect of humic ,acid, removal was better when electrified. As the reaction was prolonged in the grid flocculation-electrochemical experiment, anodic would form corrosion pits on the surface because of dissolution.

These counterions reduce the electrostatic interparticle repul-sion to the extent that the van der Waals attraction predominates, thus causing coagulation. Last is floc formation as a result of co-
