You may refer to RO membrane OEM's website such as Dow, Hydranautics, etc. For 8" pressure vessel, typical flowrate is 6 - 9.1m3/h per vessel. Just calculate the number of vessel of first stage then multiply with flowrate will give you the total flowrate. Flushing duration is subject to the rinsing of CIP chemical until clean.
