Abstract
nHistorically Crossflow Membrane modules came first in the membrane-based separation (MBS) process. Its high shear generation overcomes two non-idealities concentration polarization and subsequent fouling. Primarily, high shear generation and large surface area create a positive domain for large applications. Thereafter, feed flow rate-dependent shear generation creates a hindrance. This obstruction is overcome with Dynamic Shear Enhanced Membrane Filtration Pilot (DSEMFPs). Low surface area is a vital drawback of DSEMFPs. This radial flow membrane module with its special design develops a large surface area. Moreover, its central inlet and nine peripheral outlets reduce the large pressure drop efficiently. With all the positive properties it efficiently removes the protein from waste water. Moreover, it can work satisfactorily on plenty of wastewater treatment processes. Therefore, a detailed hydrodynamic study of the radial flow module is the primary requirement. The absence of it makes a prominent path for further investigation. Considering the importance of shear, shear stress distribution on the membrane surface is studied here. Moreover, exact velocity vector distribution in the default interior is also vital to understanding the inner hydrodynamic relationship. Additionally, vortices, turbulent kinetic energy, turbulent KE dissipation rate, and dynamic pressure on the membrane surface are also reported in this study for a complete understanding of the exact condition of the membrane surface. All these results justify the positive impact of the Radial flow system in wastewater treatment.
