Aeration Mode
Several studies have found that an implementation
of intermittent aeration and fluctuation of the aeration
intensity could offer better filtration performance than
that with continuous aeration. This technique can
mitigate cake fouling. The higher permeate flux can
be obtained by increasing the bubble frequency and
various the bubble size [47]. An intermittent aeration
is even able to enhance the de-nitrification process
[48],[49]. Moreover, fouling propensity is different
after using air injection between different locations
which can generate adequate turbulence to minimize
the fouling formation
