Abstract

See full text

A water treatment system combines a microfiltration or ultrafiltration membrane system with a downstream reverse osmosis membrane system. The MF or UF system has multiple trains of immersed membrane modules. The trains are connected to a common permeate pump. The permeate pump discharges directly into the inlet of an RO feed pump. The membrane trains are each subjected to the same suction. The permeate pumps are operated to provide the required flow to the RO feed pump at or above the minimum inlet pressure of the RO feed pump.
