Modelling of critical flux in cross-flow microfiltration
Abstract
In this study, the concept of critical flux was introduced. Below this critical flux, there will be no membrane fouling. Laboratory - scale crossflow microfiltration (CFMF) experiments were performed to investigate the effects of operational factors such as suspended particle size, cross-flow velocity, membrane pore size on the critical flux in CFMF performance. The experimental results indicated that the critical flux increased with the increase in particle size and cross-flow velocity. A hydrodynamic force balance model developed in this study predicted successfully the critical flux value.
