After Biologicals Nano, Reverse Osmosis, SWRO and MEE is already installed. Problem is Nano Can't handle such high load of BOD/COD

OK, understood. So now we need to establish what form the carbon is in. First is it particulate and can it be removed by prefiltration before the nano? If so we may be able to help using our FilterClear system.
If it is soluble then we need to check how biodegradable is the residual carbon? You could check the BOD:COD ratio and carry out a respirometry test to check. If it is biodegradable at a reasonable rate then it suggests that the biological treatment isn't working efficiently. If it is slowly degradable you could consider advanced oxidation (using UV, ozone or peroxide but probably not chlorine due to effects on membranes).
Happy to help further as needed!
