By "green" presumably you mean lowest specific energy consumption (kW.h/m3).
However which stream(s) are you optimising for, and on what parameters (water quality, recovery and flow rates).
How much waste are you generating (brine, CIP chemicals, consumables, cartridge filters, and NF/RO membrane replacements).
As others have mentioned, your "green" notion is vague, and it depends on where you define your system boundary for your "green" assessment.

TNinput=0-80mg/L (almost complete nitrif & denitrif depending on temprature ), TP=1-2mg/L, COD=5,5g/L & EC=21-23mS/cm. 3rd pass is usefull after a heavy rain when RO is loaded with raw leachate or mixed biological treated and raw leachate. Steady state recovery= 0.7, flowrate=7.5 m3/h
