Abstract:

The membrane bioreactor system (MBR) with pre-treatment of sponge tray bioreactor (STB) was evaluated at different operating conditions for treating primary treated sewage (PTS). The result indicated the successful removal of DOC with the efficiency of higher than 95%. The highest nutrient removal efficiency of 83.6% (NH 4-N) and 75.5% (PO 4-P) was observed at sludge concentration of 330mg/L. Specific oxygen uptake rate (SOUR) of activated sludge in MBR kept increasing up to 6mgO 2/gVSSh during stage IV. The sludge volume index (SVI) of less than 100mL/g during the operation indicated the good settling property of the sludge. At highest sludge concentration of 5g/L, trans-membrane pressure (TMP) was increasing dramatically during first 15d up to 25kPa; however it was only 6kPa at lower sludge concentrations. It is concluded that the system showed the highest performance at stage III with sludge concentration of 330mg/L. © 2011 Elsevier Ltd.
