Frequently Asked Questions (FAQ)
Q: What are the main pollutants in special ceramics wastewater?
The primary pollutants include high concentrations of suspended solids (SS) reaching up to 2000 mg/l, fluctuating pH levels, and potential traces of heavy metals such as Chromium (Cr), Copper (Cu), Nickel (Ni), Zinc (Zn), and Iron (Fe) depending on the raw materials used.
Q: How is suspended solids (SS) reduction achieved in this wastewater treatment?
Suspended solids are reduced from an inlet level of 2000 mg/l down to an outlet level of 200 mg/l. This is typically achieved through physical chemical processes such as coagulation, flocculation, sedimentation, and mechanical filtration.
Q: Why is maintaining a stable pH of 7~8 important for ceramics wastewater treatment?
A neutral pH range of 7~8 is optimal for the precipitation of heavy metals, ensures the efficiency of coagulants, and meets standard environmental discharge regulations without causing damage to local piping networks or ecosystems.
Q: What is the significance of the ≤30% moisture content in the mud cake?
A mud cake moisture content of 30% or less indicates efficient sludge dewatering. Lower moisture content reduces the overall volume and weight of the waste, significantly lowering transportation and disposal costs for the ceramic production facility.
Q: Can the treated outlet water from special ceramics production be recycled?
Yes, with an outlet suspended solids concentration of 200 mg/l and neutral pH, the treated water is often suitable for recycling back into initial clay preparation, washing, or dust suppression processes to promote sustainable water management.
