The electrode plate of electroflocculation equipment can use different materials according to the different substances removed to produce strong flocculation, strong oxidation, strong reduction, strong air flotation, etc., to achieve the best treatment effect. Iron, aluminum, titanium, graphite, lead dioxide, etc. are often used. Each material has a suitable field of application. The design of electroflocculation equipment and the selection of electrode plates are determined by extensive R&D tests and extensive engineering practical experience.
