ABSTRACT:

This paper presents application of CFD techniques for simulation of wastewater treatment using membrane technology. Finite element method (FEM) was used as numerical solver. A comprehensive model is developed to predict the system. The model considers equations of momentum and mass transfers. The influence of process parameters on the system efficiency was evaluated. The results showed that concentration boundary layer (CBL) is formed near the membrane surface. The modeling predictions also confirmed that the developed model is capable to evaluate the effective parameters which involve in the ammonia removal by means of membranes.
