Can an reverse osmosis membrane treat this saline water?
Thread Content
I have a question: My company has high-salinity water, with a flow rate of 720 t/d. The water quality parameters are as follows: pH: 10.47, conductivity: 37600 us/cm, COD: 400, TDS: 34500 mg/L, silicate: 400 mg/L; the remaining components are sodium chloride and sodium sulfate. Membrane treatment is intended to be used for this water. Can seawater and fresh water reverse osmosis membranes be used for this? To what extent can it be processed? What’s the cost? Please understand and provide an answer. Thank you!
If the salt concentration is too high, RO is not feasible.
Electrodialysis or evaporation crystallization treatment
This sensation is quite similar to that of seawater; it’s possible to use seawater desalination membranes for this purpose, but with a capacity of 720 t/d, the cost of desalinating seawater becomes high
To determine whether the treatment can produce water suitable for drinking, it depends on your requirements
You mentioned that the cost of desalinating seawater is relatively high – how much is it approximately? What technology is used to treat water to meet the standards for drinking water?

The salinity is too high; conventional membranes cannot handle it. Evaporation is recommended, as DTRO membranes are too expensive
This is possible for you – yields of 18%-23% can be achieved. Your parameters aren’t specific enough; for design solutions regarding the membrane treatment of high-salt wastewater, please add QQ963973833 if you have such a need
