Industrial Media Filter

Media filter is generally called deep bed filter. Water flow through the filter layer filled with filter media with a certain level of thickness and particle size to reach the filter effect. The media can be quartz sand, sand gravel, activated carbon or other granular material. The level of filtration depends on the diameter of the particles that comprise the filter bed and the flow rate of the water.

Working principle

After the water enters from the water inlet and flows through the filter layer, the suspended impurities are absorbed by the filtration layer, and the filtered water flows from the filter nozzle to the outlet. The cleaning of the filter can be done by backwash. At this time, the water flows reversely from the top of the filter nozzle, causing turbulence disturbances in the filter layer and the adsorbed impurities are released and discharged through the discharge valve. The backwashing process can be automatically completed based on the pressure difference of the inlet and outlet or timing.
