Membrane type

Main results in matter of fouling

Reference

Rotating MBR

Flat sheet

Flux augmented from 42 L/m2 h to 47 L/m2 h when rotational speed elevated from 15 to 25 r/min

[84]

Rotating MBR

Flat sheet

Membrane fouling rate is much lower in rotating MBR juxtaposed to traditional MBR for the identical energy consumption

[64]

Rotating MBR

Tubular

The fouling rate decreased as the rotational speed of the module increased

[65]

Rotating MBR

Hollow fiber

At the tested rotational frequencies, high dispersive conditions were present and significantly larger than those observed during static operation

[66]

Reciprocal MBR

Hollow fiber

Low and stable transmembrane pressure was achieved at 40 L/m2 h by use of repetitive membrane reciprocation

[67]

Helical membrane

Filter cloth sheet

27% enhancement of stable flux can be maintained by rotating a 360˚ helical membrane, compared to a rotating same sized flat membrane, at a rotating speed of 160 rpm

[1]

Baffled MBR

Flat sheet

10% - 30% increase in membrane surface shear compared with the no-baffle configuration at the same aeration intensity
