Effects of Various Operation Conditions on the Polarization Layer with Ceramic Membranes
Due to extensive usage of microfiltration membranes in industrial –scale, modeling of this processes are important and imperative. MF is one of the processes which are used for certain types of separation. In this paper, treatment of oily wastewaters with ceramic MF membranes was studied and a new approach has been suggested for modeling the concentration polarization layer in the waste water membrane system. Effects of various operation conditions (trans-membrane pressure (TMP), cross-flow velocity (CFV), temperature (T), oil concentration (C), and filtration time (t)) on the concentration profile and polarization layer are studied. A numerical solution of advection–diffusion equation has been developed using a control volume approach based on the finite element method. As will be observed, model behavior complies well with anticipations.
