The use of the dissociation effect of electricity, with the assistance of chemical coagulants, to remove pollutants from wastewater or convert toxic substances into non-toxic substances is called electrocoagulation. The reaction principle of electrocoagulation is to use metals such as aluminum and iron as anodes. Under the action of direct current, the anode is corroded, producing Al and Fe plasma. After a series of hydrolysis, polymerization, and ferrous oxidation processes, it develops into various hydroxyl complexes, multinuclear hydroxyl complexes, and even hydrogen oxides, causing colloidal impurities and suspended impurities in wastewater to coagulate and precipitate and separate. At the same time, charged pollutant particles swim in the electric field, and part of their charges are neutralized by the electrode, promoting their destabilization and agglomeration. When wastewater is subjected to electrolytic flocculation treatment, it not only has a coagulation and precipitation effect on colloidal and suspended impurities, but also can remove various pollutants from the water due to the oxidation effect of the anode and the reduction effect of the cathode.
High frequency pulse electrocoagulation power supply is a specialized electrocoagulation power supply independently developed and produced by Tongke Electric. This power supply can be used in various industries, has a wide range of applications, and has broad market prospects. It can be used in the following wastewater treatment: coating wastewater, electroplating wastewater, metal surface processing wastewater, chemical wastewater, non-ferrous metal smelting industry wastewater, electronic industry chemical and mechanical polishing wastewater, garbage leachate, leather manufacturing wastewater, printing and dyeing wastewater, phenolic wastewater, papermaking wastewater, boron wastewater, phosphorus wastewater, high fat catering wastewater, drinking water algae removal, sterilization, fluoride removal, iron removal, arsenic removal, etc.
1. Small in size and light in weight, the volume and weight are 1/5-1/10 of those of a thyristor rectifier, with a small footprint and easier mobility.
