Co - degestion of food waste and domestic wastewater by using upflow anaerobic sludge blanket (UASB) couped with a microfiltration membrane (MF)

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. | Vietnam Journal of Science and Technology 56 (2C) (2018) 118-125 CO-DEGESTION OF FOOD WASTE AND DOMESTIC WASTEWATER BY USING UPFLOW ANAEROBIC SLUDGE BLANKET (UASB) COUPED WITH A MICROFILTRATION MEMBRANE (MF) Bui Hong Ha1, The Tien Nguyen1, Thanh Tri Nguyen1, Lan Huong Nguyen2, *, Phuoc Dan Nguyen3 1 Institute for Tropicalization and Environment (ITE), 57A Truong Quoc Dung Street, Ward 10, Phu Nhuan District, HCMC 2 3 Faculty of Environment – Natural Resources and Climate Change, Ho Chi Minh City University of Food Industry (HUFI), 140 Le Trong Tan, , Tan Phu District, HCMC Faculty of Environment and Natural Resources, Ho Chi Minh City University of Technology, 268 Ly Thuong Kiet St., District 10, HCMC * Email: lanhuongba@ Received: 09 May 2018; Accepted for publication: 21 August 2018 ABSTRACT 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/. Removal efficiencies of TSS, tCOD, nitrogen and phosphorus were evaluated. The potential of biogas production also was determined. The results showed that removal efficiency of TSS and tCOD at above mentioned fluxes, respectively, reached %, %, % and % for TSS and %, %, % and % for COD. Also, the yield of biogas production was L/gCODremoved, L/gCODremoved, L/gCODremoved and L/gCODremoved, respectively, in corresponding with above mentioned fluxes. This study indicated that application of the lab-scale model of anaerobic membrane bioreactor for co-digestion the mixture of WF and DWW utilized the concentrated stream of membrane module to increase the biogas yield and to reduce amount of waste solid in .
