High shear devices rotating systems

Rotating disc systems have also been described as efficient devices to overcome flux limitation due to matter deposit on membrane surface during cross-flow filtration [40]. The problem of erosion of a macroscopic particle solid deposit on a rotating disc membrane has been quantified by Aubert et al. [41]. The influence of the transmembrane pressure, the thickness of the initial deposit and the pore size on the critical shear stress have been investigated and described by empirical fits. It results from this study that fouling is more efficiently eliminated at high Ap and large pore size.
