Abstract
The characteristics of non-woven fabrics as solid/liquid separation media in a MBR application have been studied in this paper. To understand the effect of particle properties on filtration performance, inorganic and microbial particle filtrations were studied simultaneously. The results showed that there was no significant decline of permeate flux during 120 h operation for inorganic particle filtration. Comparatively, non-woven fabrics were fouled rapidly for microbial particle filtration and significant decline in permeate flux was observed during experimental periods. However, low effluent suspended solids was achieved rapidly due to the denser cake layer on the fabric surface. This study has demonstrated that non-woven fabric materials could be used as solid/liquid separation media in membrane bioreactors for wastewater treatment. An appropriate operating strategy, like optimum operating flux and fouling control, is needed for long-term stable operation.
