alginate, are used to represent natural matter and extracellular organic
matter, respectively. It was found that backwashing was more effective
for sodium alginate fouling than for humic acid fouling. Rinsing could be
optimized under an integrated mode of backwashing and forward
flushing, while the time, pressure, velocity, and volume are some of the
optimizing factors during the process. Liang et al. [39] evaluated
different washing methods for cleaning of the ultrafiltration membrane
by algae, and found that 20 min duration of backwashing followed by
forward flushing and 4 h duration of integration of sodium hydroxide
and sodium hypochlorite were of benefit for the membrane cleaning.
Wang et al. [15] suggested that a cross-flow velocity of 1.6 m/s ca
