Brewery effluent is usually very well treatable and with the high organic loads, the SBR technology is absolutely reliable and should give you TDS values well below your target of 500 mg/l. But for that you need good floc forming for final settling and for this purpose you should check and correct your pH, which should be somewhere between 7,0 and 8,2 in your reactor.

All other technologies are (too) expensive and need much monitoring and corrective measures.
