Electro-oxidation electric coagulation flotation machine technology is a combination of electrolysis, flocculation and flotation.
Principle of electro-oxidation electrocell air flotation
    For the purification of water in place of aluminum or iron as the anode in the electrolysis process by dissolving the anode and transferred to the trivalent aluminum ion or a divalent iron ion hydrolysis solution becomes effective coagulant dispersed impurities. Sun and Moon from the reaction of the formula sheet electrode, thereby generating oxygen bubbles at the anode to produce hydrogen bubbles at the cathode.
    When these bubbles rise, the suspension will be brought to the surface, forming a scum layer on the surface; on the other hand trivalent aluminum ions (or bivalent iron ions) and its hydrolyzed polymeric product of interaction with the flocculation of suspended impurities. Electro-coagulation flotation method compared with the conventional coagulation method has many advantages: eliminating the need for any chemical coagulant dosage; electrocell no anionic flotation method, no impurities; electric field formed by the flocculation reactor, the particles mutual exclusion between the original becomes attracted to coalesce; electrocell flotation in the reaction O2 and H2 flotation of fine bubbles, light adsorption of suspended particles or hydrophobic substances, so that it is separated from the water; by removing suspended solids and use of special electrode to achieve the effect of removing bacteria.孫金勇 other electrical flocculen domestic wastewater treatment, the study found that under certain conditions, the turbidity removal efficiency of 95%, COD removal rate was 59%.
    The method and dosing flocculant chemical coagulation method compared to the kind of pollutants can be removed widespread, rapid response, wide applicable PH range, and sediment compaction, good clarifying effect. Widely used in printing and dyeing wastewater treatment, chemical dyes, hospitals, leather, electroplating and other industries.
