d mode of backwashing and forwardRinsing here is consisted of backwashing and forward flushing,
which are usually applied following each other. Periodical rinsing can
avoid the aggregation or dense attachment of particulates on the
membrane surface due to the reverse direction force from a higher
backwashing pressure or surface shear from a high velocity, and cause
reduction or slower rate of concentration polarization. Some rinsing
way may be effective for cleaning some certain foulant; some for others.
Katsoufidou et al. [70] investigated the fouling phenomena of
ultrafiltration by different organic substances, and found that different
organic matters presented different fouling mechanisms. In the
experiment, two model substances, commercial humic acid and sodiu
