Electric flocculation reaction principle is based on aluminum, iron and other metal anode, in direct current (dc), under the action of anodic dissolution, plasma, Al, Fe in the series of hydrolysis, aggregation, and ferrous oxidation process, and developed into all kinds of hydroxy complex, polynuclear hydroxy complex that hydroxyl, the colloidal impurities in waste water, suspended impurities coagulation precipitation and separation, charged particle pollutants at the same time swimming in the electric field, its part of the charge by electrode and prompt its steady coagulation.
