The purpose of this study was to examine the effect of feed water quality and operational
parameters on the efficiency of backwashing. In this study, a series of fouling experiments were
first performed under various operating conditions. The primary operating parameters varied
throughout the experiments were particle concentration, operating pressure and solution ionic
strength. A theoretical model for flux decline due to cake formation was evaluated and utilized
to determine the structure of the cake layer formed during fouling experiments. Following each
fouling experiment, the membrane was backwashed in order to relate the backwash efficiency to
both physical and chemical parameters. Finally, a theoretical value for the particle packing
density of the cake layer calculated from the model was correlated to the backwash efficiency in
order to elucidate the effect of cake structure on the efficiencies of backwashing. Includes 6 references, figures.
