Influence of Organic Loading Rate on Methane Production from Brewery Wastewater in Bioelectrochemical Anaerobic Digestion

Blog Article

The effect of bioelectrochemical anaerobic digestion (BEAD) on the methanogenic performance of brewery wastewater at different organic loading rates (OLRs) was investigated and compared to conventional anaerobic digestion.A continuous BEAD reactor was used to treat brewery wastewater at different OLRs of 2, 4, 8, 16, and 20 g COD/L.d.The experimental results showed that the methane production was yale law school colors gradually increased from 0.

48 L/L.d at an OLR of 2 g COD/L.d to 5.64 L/L.

d at an OLR of 20 g COD/L.d.The methane production of the BEAD system was significantly higher than that of the conventional anaerobic reactor, indicating that BEAD has a better treatment effect for brewery wastewater.The performance turbo air m3f24-1-n of the conventional anaerobic reactor was significantly reduced especially at an OLR of 16 g COD/L.

d, while the BEAD system could withstand a higher OLR.Bioelectrochemical systems provide a completely new platform for the anaerobic treatment of brewery wastewater and greatly improve the operation of anaerobic processes.
