    DAF Treatment Plant | Industrial Effluent Treatment System,

    Dissolved air flotation [DAF] is a treatment process which removes suspended solids, oil and grease from wastewater. Many applications use the DAF process but it is particularly useful for industrial wastewater treatment as it can reduce COD by up to 90%.Dissolved Air Flotation (DAF) Machine for Water Treatment,,Dissolved Air Flotation machine (DAF) is mainly used to separate and remove micro suspended substances with density closed to the water. It is air flotation method that dissolved system produces dissolved water through the air will be forced into water under pressure by air compressor and then large amounts of micro bubbles will be produced in water by fast pressure reduction release.Oil Water Separator--Dissolved Air Flotation Unit (DAF,,Dissolved Air Flotation machine, short for DAF, it is main machine used to remove the TSS and oil. It is widely used in the pre-treatment process for the wastewater treatment. The TSS and oil removal rate can reach above 90%, at the same time it can remove some COD around 30~50%.
