Abstract:

A pilot scale membrane bioreactor hybrid system (MBR-HS) was evaluated for municipal wastewater treatment. This novel system comprised of a granular activated carbon-sponge fluidized bed bioreactor (GACS-FBBR) followed by a submerge membrane bioreactor (MBR) with the capacity of 2L/min. The results indicated that the MBR-HS could effectively remove 90% DOC and 95% NH4-N. PO4-P removal efficiency was remained stable at about 70% throughout the experiment. Specific oxygen uptake rate (SOUR) of activated sludge increased from 0.72 to 2.21mg O2/gVSSh for the first 10days and then followed by a steady stage until the end of experiment. Sludge volume index (SVI) was always below 50mL/g, demonstrated an excellent settling properties of sludge. The system also showed an achievement in terms of low trans-membrane pressure (TMP) development rate. The TMP increasing rate was only 0.65kPa/day, suggesting GACS-FBBR can be a promising pre-treatment for MBR. © 2013 Elsevier Ltd.
