Glass Edge Grinding Wastewater Treatment Systems Customizable

• Primary pollutants: Glass powder (silica powder) produced during cutting and edging.
• No organic matter, inorganic salts, or other ionic substances are added in the wastewater-generating process, and no ionic pollutants are produced during production.
• Due to the characteristics of the production process, wastewater discharge is balanced, with minimal fluctuations in water quality and volume.
• When recycled, the wastewater has a high suspended solids (SS) content of ≥500 mg/L, a chromaticity of 200–400 times, and a pH of approximately 7–8.

• Turbidity ≤1 NTU
• Chromaticity ≤15 times
  Note: Conventional tap water standards: Turbidity ≤3 NTU, Chromaticity ≤15 times.

1. Wastewater is collected via open channels and enters a regulation tank, which balances water volume and quality.
2. The regulation tank is equipped with pre-aeration mixing, and aeration pipes at the bottom prevent glass powder from settling.
3. Two lift pumps transfer the wastewater from the regulation tank to a reaction tank, where PAC (polyaluminum chloride) and NaOH are dosed.
4. Formed flocs are separated in an SS dual-selection integrated machine:
   • Large, easily settleable suspended solids rapidly settle to the bottom hopper.
   • Fine, hard-to-settle suspended solids are lifted to the water surface by microbubbles and discharged into the sludge tank.
5. The clear water compartment (middle section) discharges effluent into a gravity sand filter for security filtration, ensuring water safety.
6. Treated water from the sand filter flows to a reclaimed water tank for reuse in edging and edging washing machines.
7. Sludge from both sections of the SS dual-selection machine is discharged to a sludge thickening tank, dewatered by a plate-and-frame filter press, and bagged for off-site disposal.
