This study investigated anaerobic co-digestion of food waste (FW) and domestic wastewater (DWW) by upflow anaerobic sludge blanket (UASB) combined with an external microfiltration membrane (MF) - AnMBR. The model was conducted with varying of hydraulic resident time of 72 h, 48 h, 36 h and 24 h in corresponding with varying of flux, respectively, were 47, 70, 94 and 141 L/m2 .h. Removal efficiencies of TSS, tCOD, nitrogen and phosphorus were evaluated. The potential of biogas production also was determined. | Co-degestion of food waste and domestic wastewater by using upflow anaerobic sludge blanket (UASB) couped with a microfiltration membrane (MF)
