With TDS your choices are to look for a coagulant if the TDS is associated with DOC (and that is probably what adsorption has removed); otherwise you are probably looking at a membrane system.
Anaerobic digestion, as mentioned below, may help, but only of the TDS is associated with organic material, and the anaerobic digestion may release further TDS back into the system, depending upon the system and operation being used.

Coagulation, aeration and sedimention with retention period of 24 hours was applied prior to discharge. The effluent with high TDS is actually the treated effluent fro the ETP.
