The flocculating dosing device is used to add flocculating agent to the circulating water, and the raw water is pressurized by the boosting pump. After the flocculating agent is stirred by the pump impeller, the fine solid particles in the raw water are suspended and the colloidal substance is subjected to micro flocculation reaction. The flocs having a volume greater than 5 microns are generated and flow through the filtration system piping into the highly efficient asymmetric fiber filter, and the flocs are retained by the filter material. The system uses gas and water combined flushing, backwashing air is provided by the fan, and backwashing water is provided directly by tap water. The system's wastewater (high-efficiency automatic gradient density fiber filter backwash wastewater) is discharged into the wastewater treatment system.
