The colloids, microparticles, microorganisms and macromolecules is the suspension can be removed effectively by the crossflow-microfiltration. Therefore, crossflow-microfiltration has been applied widely in the processes of solid-liquid separation. Furthermore, because the direction of the feed flow is tangential to the membrane surface in crossflow-microfiltration, the formation of a filter cake is minimized and the pressure drop is lower compared to the convention filtration process. The behavior of CFMF of a colloidal suspension with the presence of macro-molecules was studied. The analysis is based on the membrane blocking/fouling which increases flow resistances and causes flux decline. Cake filtration model was used to fit experimental data. From this model, the most of the activated carbon particles were too large to enter the membrane pores and were deposited as cake on membrane surface. |
