Hi

May be if you eliminate the pigments and additives by ferric chloride at pH=7 to 8 and then start your MBR process it reduces your process time and the resulted COD as well. More over, you can ozonate the treated waste water in presense of a UV module with proper debi. I suggest that some amount of the concentrate of the RO  system shoulbe conducted to the entrance of the MBR process to reduce the contimination load and put more water in recycle sequence.

Good luck
