A comparison of azimuthal and axial oscillation microfiltration using surface and matrix types of microfilters with a cake-slurry shear plane exhibiting non-Newtonian behaviour

Extensive review about industrial and laboratory dynamic filtration modules: Scientific production, configurations and performances

“…The azimuthal movement oscillates at 3 degrees with 20 to 100 Hz, the highest shear stress of 240 Pa is reached. The vibration mode did not influence the filtration performance, while it corresponded to the shear stress peak delivered by the oscillating system [217].…”

“…A cylinder membrane (14 mm outside diameter, 64 mm membrane working length) was immersed in calcite suspension, and two modes of oscillations were performed [217]. The axial oscillations can be operated with an adjustable displacement and frequency up to 100 Hz.…”

Modified Clay Filters for Purification of Petroleum Products Contaminated Water

“…Water absorption test measures the amount of water absorbed by wetted surface of ceramic filters. The test can be used to predict the performance of ceramic filters for specific applications and provide information on degree of compactness, apparent porosity, apparent relative and bulk density as well as comparative performance of ceramics filters [20,21,22]. Table 1 shows the results of the water absorption test, the mass of the filters was measured until a constant mass was reached and the values were used to determine water content, swellability and porosity of the candle filters.…”

Novel methods to induce complex coacervation using dual fluid nozzle and metal membranes: Part I – Use of metal membranes for emulsification

“…In addition, it is possible to predict or engineer the size of the emulsion droplets by a balance of capillary and drag forces during the droplet formation (Kosvintsev et al, 2005). A handful of recent works studied the application of membrane emulsification, such as production of eco-friendly emulsions (Santos et al, 2015), comparison of azimuthal and axial oscillation microfiltration for non-Newtonian fluids (Holdich et al, 2018), preparation of micro and nano emulsions (Vladisavljević, 2019), the use of annular crossflow membrane using a single-pass (Holdich et al, 2020) and use of tubular stainless steel membrane to produce Keratin-Chitosan coacervated capsules in continuous mode (Wilson et al, 2021).…”
