Research Project Summary:

The membrane bioreactor is an efficient technology for wastewater treatment and reuse. It shows many advantages over the conventional process by its highly improved effluent quality, increased organic loading, reduced land occupation and low surplus sludge production . In such a process, membrane-fouling control is of great importance for stable operational performance. With the fouling of the membrane, membrane permeability will decrease and energy costs will increase. In general, membrane fouling is attributed to factors such as sludge particle deposition, adhesion of macromolecules to the membrane surface, and pore clogging by small molecules, among which cake layer formation by sludge.

The present study aimed to investigate appropriate operating parameters and fouling mechanisms in order to reduce membrane fouling in MBRs through using submerged hollow fiber membrane bioreactor, hence improving the overall process performance. These include:

1. mixed liquor suspended solids (MLSS) concentration in the reactor
2. back flushing (cleaning) frequency
3. critical flux and flux control
4. aeration intensity and aeration mode (continuous versus intermittent)
