DAF for oily wastewater treatment

The principle

Placed in to purify water metal anode aluminum or iron, in the process of electrolysis by the anodic dissolution and transferred to the trivalent aluminium ions in solution or bivalent iron ion hydrolyzed to become effective flocculant distributed impurities.Thus the oxygen bubbles at the anode, the hydrogen bubble on the cathode.

The method and adding the flocculant, compared to chemical coagulation method can remove the pollutant is widespread, responsive, suitable for wide PH range, and sediment is close-grained, clarify the effect is good.Widely used in printing and dyeing, dye, leather chemical industry, hospital wastewater treatment, electroplating and other industries.

flocculation 
Plate electrode electric flocculation equipment can be selected according to remove material different and different materials, produce strong flocculation, strong strong strong oxidation, reduction, the effect such as air flotation, in order to achieve the best treatment effect, often used with iron, aluminum, titanium, graphite and lead dioxide, etc.Each material has its suitable for the fields of application, the electric flocculation equipment design and selection of electrode plates is through a large number of research and development test and rich experience in engineering practice and determined.According to a large number of test electric flocculation equipment for all kinds of removing impurity substance in waste water is as follows:oil .COD .SS. SiO2, colloidal silicon, organic silicon. Heavy metal ions. Chroma . hardness. Bacteria, viruses,
