In this study, we examine the improvement of fouling control of hollow fibre membranes with mechanical vibrations in the dead-end filtration of an inorganic suspension. Hollow fibres with diameters of 1.7 mm and 2 mm vibrating at moderate frequencies (0-15 Hz) and small amplitudes (0-12 mm) were submerged vertically in a 4 g/L Bentonite solution. Experiments were then conducted at both constant permeate flux and constant suction pressure conditions. The results showed that the membrane performance can be greatly improved when the vibration frequency or the vibration amplitude increases beyond a threshold magnitude. For example, over 90% reduction in the membrane fouling rate was achieved at 8 mm amplitude and 8 Hz frequency vibration compared to no vibration. Experiments were also conducted with 1% and 2% fibre looseness. The results showed that a small looseness can reduce the membrane fouling and increase the permeate flux under vibrations, which can be mainly attributed to the additional lateral movement of the fibres induced by the looseness. A comparison of vibrating the hollow fibres with and without the holding frame was also carried out to determine the effects of turbulence generated by the vibrating holding frame used in the experimental setup. Particle Image Velocimetry (PIV) measurements were performed to quantify the associated turbulence inside the membrane reactors. It was confirmed that the turbulence generated by the vibrating frame was more obvious at a high vibration frequency. However, it had little influence on the membrane filtration performance. Overall, the results from the present study confirm that at moderate frequencies, the cake layer resistance can be reduced substantially by vibration due to the dynamic shear enhancement on the membrane surface.
