High-voltage pulse electrocoagulation equipment is the latest generation of electrochemical water treatment system in the world. This technology breaks through the traditional low-voltage and high-current electrolysis method, adapts the high-voltage and low-current (high-voltage pulse electrocoagulation method – HVES) electrolysis method. Using the principle of the electrochemistry, and electrochemical reaction is generated by applying a high voltage to convert electrical energy into chemical energy, and in a specific tank, the organic or inorganic pollutants in the wastewater are oxidized and reduced, and then condensed and floated. Separation of pollutants from water can effectively remove heavy metals such as Cr6+, Zn2+, Ni2+, Cu2+, and Cd2+ from wastewater, CN, oil, phosphate, and various harmful pollutants such as COD, SS, and color.
