Dear Mr. Arsalan,
If you are intending to reach Zero Liquid Discharge ZLD, then there is no ground to refer to Reverse Osmosis. To achieve ZLD you are intending to buy a flash evaporator and a crystallizer, all you have to do is to implement an accurate flash evaporator, and your situation is already fine to bypass any reverse osmosis as long as your wastewater is already of high TDS.

Yes, I agree with you too.
- But for the ZLD process, the TDS should be high, for example, the TDS is 82000, and I do not think it is worthwhile to refine this wastewater directly to the LDP process, but our waste should have at least a TDS of over 150000 ppm.
- On the other hand, we export reverse osmosis waste because in our country (Iran), unfortunately, there is currently no possibility of reverse osmosis.
- Please provide it if you have any suggestions.
- Thank you very much for your guidence and suggestions.
