The size of EDF secondary filter screen is small, and the operation is flexible. According to different ways, the size of the filter mesh can be changed to separate the solid debris beyond the regulation from the water flow. The backwash effect is good, and the separated debris can be quickly discharged. The local mesh backwashing has little interference on the overall flow and ensures the stable water supply. The backwashing operation is automatically controlled by the differential pressure instrument to eliminate the separated debris in time.
