Abstract—Based on submerged hollow fiber membrane module reaction to elute pollutants on membrane surface, as shown in
operation performance, backwashing pressure (BP) and . In applications, CIL is more simply and frequently. CIP
backwashing flux (BF), the two key parameters of cleaning in line is mainly used while membrane modules are seriously fouling
(CIL) operation, were analyzed in this work. The results monly 1 or 2 times per year [4].
demonstrated that the optimal CIL condition should made the
backwashing solution cover the farthest hollow fiber end.
Additional to that, when the module was installed higher than
effluent point,
