Membrane filtration has become a primary technology for ensuring the safety and efficiency of treatment of wastewater. This work presents a simulation of wastewater using hollow fiber and tubular membranes. Mass transfer and hydrodynamics of the system were investigated by solving conservation equations. The conservation equations solved are the Navier-Stokes and continuity equations which were solved numerically using the computational fluid dynamics (CFD). Finite element analysis was applied for numerical solution of the system equations. The influence of effective parameters on the mass transfer and hydrodynamics of the process removal was investigated. The distribution profiles of concentration, concentration polarization, velocity, and pressure were obtained and compared between the hollow fiber and tubular membranes for the solute. The results of the simulation confirmed that feed and solvent velocities are the most important parameters in the separation. It is also indicated that the hollow fiber membrane reactors showed good results in the removal process from aqueous solutions.
