Alternating current wastewater desalination process
Thread Content
Wastewater has a high salt content, making biochemical treatment difficult; effective desalination processes are needed for glyphosate and bisphosphonates
Previously, a treatment process for wastewater containing sodium sulfate was designed: negative-pressure double-effect evaporation was followed by crystallization and centrifugation to obtain solid sodium salts, after which the wastewater could be discharged in compliance with standards, while the sodium salts were packaged for shipment.
If the wastewater is relatively clean and contains no excessive suspended solids, a nanofiltration membrane filter can be used to remove salt ions, which is an ideal solution. The cost of implementing this method is not high; it depends rather on the volume of wastewater to be treated. For example, nanofiltration is used to remove salt ions contained in paper brightening agents, and it is also widely applied in the separation of salt ions from reactive dyes, with good results.

We are considering that the cost is too high; removing salts from glyphosate wastewater is no easy task
It must be treated; otherwise, biochemical treatment is not possible
Sodium sulfate has a high value for recovery; of course it is worth recovering!
