Process 1

This process can remove most organic matter from high-salt wastewater through pretreatment and electrolytic advanced oxidation, ensuring the quality of salt produced from zero discharge. Meanwhile, it reduces the scale of the evaporation and crystallization unit via DTRO concentration and volume reduction, significantly lowering the wastewater treatment operating cost.

1. Low operating cost

2. High quality of produced salt

3. High degree of automation

4. Good quality of reused water

Application Fields

Zero discharge of high-salt and high-organic-matter wastewater

Process 4

This process realizes the deep resource utilization of sodium sulfate produced from high-salt wastewater. By adding ammonium bicarbonate, through processes such as crystallization, metathesis reaction and evaporation, low-value sodium sulfate is converted into high-value sodium carbonate and ammonium sulfate, further reducing the treatment cost of high-salt wastewater.
