Dear Mallikarjuna AlapakaThe ...

Dear Mallikarjuna Alapaka The question is very generic and I would need a lot more details before I try to help you - i.e. you need to optimise the system in terms of what? of biology and treated water quality, of membrane performance, of enegry consumption, etc.? However, to start with, I would suggest you get hold of Simon Judd's book titled "The MBR Book", preferably its second edition, that both will make you become more familiar with the membrane bioreactor theory and will have the chance to be provided with case studies that may be of help.
