The reaction principle of electro-flocculation is to use metals such as aluminum and iron as anodes. Under the action of direct current, the anode is corroded to produce Al and Fe plasma. After a series of hydrolysis, polymerization and ferrous oxidation processes, it develops into various hydroxyl groups. Complexes, polynuclear hydroxyl complexes and hydroxides make the colloidal impurities and suspended impurities in the wastewater agglomerate and precipitate and separate. At the same time, the charged pollutant particles move in the electric field, and part of the charge is neutralized by the electrode. Promote its destabilization and aggregation. When wastewater is subjected to electrolytic flocculation treatment, it not only has the effect of coagulation and precipitation on colloidal impurities and suspended impurities, but also can remove many pollutants in the water due to the oxidation effect of the anode and the reduction effect of the cathode.www.khnwatertreatment.com
