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.
