Acoustic fouling characterization

Most of the studies about the use of acoustic waves for fouling characterization gave qualitative information about the cake layer (relative amplitude variations) and concerned flat-sheet membranes. The originality of the method presented here [9] is to give the possibility of extracting qualitative information by using another characterization method in parallel. [Pg.244]

Optical and Acoustic Methods for in situ Characterization of Membrane Fouling ... [Pg.229]

The monitoring of membrane fouling with acoustic waves is one of the few non-invasive methods potentially applicable to commercial-scale modules. Nonetheless, amplitude measurements can only provide qualitative characterization (relative amplitude variations) of the cake formation process because of the lack of knowledge about the propagation mode of an acoustic wave in a deformable deposit.
