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

Abstract : By maintaining a high shear rate, dynamic filtration (DF) provides excellent performances in controlling fouling and improving flux during filtration. Many DF devices comprising a mechanical movement generated by the rotation, oscillation and/or vibration of one element have been developed. Based on the bibliometric analysis, new applications and technologies related to DF have become the new research hotspots. Major applications were reported in food processing, water treatment and bioprocess engineering. With a precise definition of the concepts of oscillation and vibration, 55 DF modules have been classified into 15 different types according to movement and shape (filtration cell, membrane, impeller, disk...). But it appears that it remains a great challenge to complete the knowledge on the flow of fluid inside DF modules because of their complex geometries. Global, semi-local and local investigation of hydrodynamics have been detailed. They not only make it possible to estimate performances but also to help to calculate energy consumption according to operating conditions. This review presents the main characteristics of DF devices and existing applications. These empirical results are already beneficial for the selection of DF devices for a dedicated application. However, a better understanding of local and temporal variations in pressure and shear stress is still necessary to refine the choice of a device and the operating conditions. The overarching aims propose to report the main criteria that will help engineers select the DF module or identify the scientific and/or technological bottlenecks about hydrodynamics or applications.
