Combined technique of nanofiltration and electrodialysis NF-ED

About Combined technique of nanofiltration and electrodialysis NF-ED

Through the combined application of nanofiltration and electrodialysis, the raw materials can be fully utilized, the output of wastewater can be reduced, the cost can be reduced, and the income can be increased.

Step1

Bisglyphosate production wastewater, sodium chloride 22%, formaldehyde 1600 ppm, bisglyphosate -1.2%, total phosphorus 12,000 ppm;

Step2

Nanofiltration for salt separation and simultaneous concentration of bisglyphosate;

Step3

Electrodialysis treatment of nanofiltration concentrate, separating salt from organic matter;

Step4

Nanofiltration brine and electrodialysis brine evaporation and crystallization, organic wastewater concentration and incineration.
