Dear Mr. Kumar,
as first a reliable analysis and data addressing the volume to be treated should be transmitted.
Beside all the valuable solutions offered, in order to reduce the TDS the last step needs to be a membrane based treatment. But if reverse osmosis is necessary or nanofiltration could achieve the limit value in the effluent needs to be assessed in detail. In any case for the successful processing of this kind of wastewater we strongly suggest to use membrane elements or membrane modules respectively based on the "open channel technology".
