초록

Single-staged anaerobic fluidized ceramic membrane bioreactor (AFCMBR) was operated at 25oC for the treatment of low-strength synthetic wastewater with chemical oxygen demand averaging 260 mg/L. Tubular ceramic membrane consisting of aluminun dioxide (Al2O3) with 0.5 μm pore size was used. Overall COD removal was achieved as 87-95% with effluent COD concentration of 15-30 mg/L at hydraulic retention time (HRT) ranging from 1 to 3 hr depending upon permeate flux. Maintenance cleaning with NaOCl solution improved GAC scouring to reduce biofouling effectively, which allowed TMP less than 0.15 bar at 20 L/m2.hr. Energy required to operate the AFCMBR was reduced to 0.038 Kwh/m3 at 17 L/m2.hr, which was about 17% of the electrical energy converted by methane produced by AFCMBR.
