Simulation of the Effect of Cartridge Geometry on Membrane Separation Processes

Nodaway, membrane methods such as ultrafiltration have been considered to separating pollutions from fluids. The governing equations indicate the role of cartridge geometry on the separation process. The present study is carried out to investigate the effect of cartridge geometry on the separation performance of a hollow fiber ultrafiltration system. Numerical Modeling are divided into three categories, include circle, square, and triangle. The region including fibers is considered as a porous medium. Results show in the same conditions, the use of square and triangular geometry reduce transemembrane pressure, cake thickness and consequently the cake resistance and the membrane resistance compared to circle. Also, triangle geometry has shown better performance under changes in inflow and packaging density and the time to reach the same thickness of the cake is more than the other two geometries.
