You havent considered any anaerobic digestion technology.
Primarily, I feel that incorporation of a pre-aeration anaerobic digester can significantly help you in achieving the desired norms. The RO and other membrane technologies again result in high end reject wastewaters, the disposal of which is again an issue.
Anaerobic phase can help in reduction of the organic load without any significant electrical energy addition. Also, the reduction efficiency of this reactor can reduce the load on the further units, as well as, provide a source of fuel gas, which can be used for gas generation. The organic load you have is high, so gas generation will be significant as well. The calculation is
{(FLOW*ORG.LOAD [COD]) / 1000} x 0.5 x 0.45
Here, 0.5 is the percentage of COD Reduction (50%), 0.45 is methane content of this gas (45%)
Further, thumb rule suggests that 12000 m3 of methane generates 1MW electricity.

Thanks Sagar, there isn't any room to change the upstream processes (already existing) and hence the search into AOP's.
