... the wastewater used. The duration and frequency of backwashing are vital parameters for successful long-term operation of a membrane system. The backwash duration and frequency required to remove the reversible component of the foulant layer increased with time during the operation of membrane an ...

... but also retards the permeability decline. In comparison to the normal backwashing in which flow is reversed across the membrane once during each backwash cycle, two consecutive backwashing pulses during each cycle is an optimized operation. A chemical cleaning may be required to restore the initia ...
