Tofu Wastewater (TWW) Treatment and Hydrogen (H2) Production by Using A Microbial Electrolysis Cell (MEC) System
High organic pollutant in tofu wastewater (TWW) raises a negative impact on environmental sustainability and health.Therefore, the TWW must be treated before it is discharged into the environment. Microbial electrolysis cell (MEC) is one ofthe green technologies that can be used to treat wastewater and generate hydrogen as well. This work tries to investigatethe performance of MEC based on the decrement of organic pollutants in TWW. Some important parameters of organicpollutants in TWW such as chemical oxygen demand (COD), biological oxygen demand (BOD), total suspended solids (TSS),total dissolved solids (TDS), total solid (TS), and pH were evaluated before and after MEC operation. The results showedthat the COD and BOD levels decreased around 56% and 35% while pH increased from 7.90 to 7.16. Additionally, the TSS,TDS, and TS decreased by around 35.0%, 45.5%, and 33.2%. In addition, the optimum hydrogen yield (YH2) and hydrogenproduction rate (QH2) were obtained at 114±0.1 mLH2/g COD 360±20 mL H2/L/d. Overall, the MEC system could beused to reduce the level of organic pollutants in TWW and generated H2at the same time.
