CFD Simulation of a Transient Ultrafiltration System for Concentrating Bromelain From Pineapple Wastes

In this research, using an ultrafiltration (UF) membrane to purify bromelain enzyme during the production of bromelain enzyme from pineapple brings high efficiency in product quality.This study evaluated membrane filtration using computational fluid dynamics (CFD) simulations.First, the simulation builds a computational model based on the actual UF module to evaluate the filtration performance and the fluid behavior through the filter.Additionally, The Navier -Stokes equations and conservation equations are used to solve the conditions in the study of membrane filtration.The transient mode is used, corresponding to a time level of 3500s.Under the turbulent flow model (SST -), it is necessary to predict the velocity and pressure behavior as well as the parameters of the fluid inside the equipment.The results show that the bromelain enzyme obtained is 99.17%, and the maximum pressure when the process is stable is 236 kPa.The simulation shows that the mathematical model and the simulation results are consistent with validated experimental data.
