“…This work used ultrafiltration of skimmed milk in two different module geometries and validated the results with CFD. Feron et al [11] proposed a novel test cell for gaseous separations. This test cell was intended for characterization of high flux flat sheet membrane with uniform mass transfer over the membrane area and the cell design was verified with numerical simulation.…”

Gas flows in laboratory membrane test cells are often assumed to be uniform due to the relatively small feed volumes and ideal mixing of gas mixtures such as air. Scientific literature on characterization of gas flow distribution in the feed volume above the membrane in laboratory cells is limited. (1) (2008) 58]. In this work, the conventional cell used in laboratories was first examined to determine the uniformity in flow distribution and its effects on membrane performance. Using a combination of experimental and numerical methods, the feed flow distribution in the conventional cell was found to be skewed towards the far (retentate) side of the feed volume and also resulted in short-circuiting of the gas mixture to the retentate outlet. A new design for laboratory cell was proposed and experimentally validated. This modified cell was found to have a more uniform flow distribution than the conventional cell, consequently leading to improved separation performance.Crown

“…Successfully achieving these objectives is dependent upon proper design and optimization of the treatment water flow systems within the plant. Numerous studies [ 35 , 36 , 37 , 38 , 39 , 40 ] have employed CFD tools to gain an insight into the phenomena taking place inside membrane modules [ 33 , 41 , 42 , 43 , 44 ] and to improve the overall performance of modules. As an analysis tool, CFD provides the ability to modify operating conditions, fluid properties and geometric characteristics of the flow channels in a flexible but defined way [ 31 ].…”

Numerical Modelling Assisted Design of a Compact Ultrafiltration (UF) Flat Sheet Membrane Module

The increasing adoption of ultra-low pressure (ULP) membrane systems for drinking water treatment in small rural communities is currently hindered by a limited number of studies on module design. Detailed knowledge on both intrinsic membrane transport properties and fluid hydrodynamics within the module is essential in understanding ULP performance prediction, mass transfer analysis for scaling-up between lab-scale and industrial scale research. In comparison to hollow fiber membranes, flat sheet membranes present certain advantages such as simple manufacture, sheet replacement for cleaning, moderate packing density and low to moderate energy usage. In the present case study, a numerical model using computational fluid dynamics (CFD) of a novel custom flat sheet membrane module has been designed in 3D to predict fluid flow conditions. The permeate flux through the membrane decreased with an increase in spacer curviness from 2.81 L/m2h for no (0%) curviness to 2.73 L/m2h for full (100%) curviness. A parametric analysis on configuration variables was carried out to determine the optimum design variables and no significant influence of spacer inflow or outflow thickness on the fluid flow were observed. The numerical model provides the necessary information on the role of geometrical and operating parameters for fabricating a module prototype where access to technical expertise is limited.
