As time progresses, the efficiency of the membrane will be reduced. In general, the salt
rejection does not change significantly until two or three years after installation when
operated on properly pretreated feed water. The permeate flow rate wi
slightly after one year of operation, but can be extended with diligent flushing and
cleaning of the system. A high pH and/or precipitation of hardness can cause
premature loss in rejection
