Findings from Woosong University Has Provided New Data on Hydrology (High speed municipal sewage treatment in microbial fuel cell integrated with anaerobic membrane filtration system)

By a News Reporter-Staff News Editor at Science Letter -- Current study results on Hydrology have been published. According to news reporting out of Taejon, South Korea, by NewsRx editors, research stated, "A cylindrical two chambered microbial fuel cell (MFC) integrated with an anaerobic membrane filter was designed and constructed to evaluate bioelectricity generation and removal efficiency of organic substrate (glucose or domestic wastewater) depending on organic loading rates (OLRs). The MFC was continuously operated with OLRs 3.75, 5.0, 6.25, and 9.38 kg chemical oxygen demand (COD)/(m(3).d) using glucose as a substrate, and the cathode chamber was maintained at 5-7 mg/L of dissolved oxygen."

Our news journalists obtained a quote from the research from Woosong University, "The optimal OLR was found to be 6.25 kgCOD/(m(3).d) (hydraulic retention time (HRT) 1.9 h), and the corresponding voltage and power density averaged during the operation were 0.15 V and 13.6 mW/m(3). With OLR 6.25 kgCOD/(m(3).d) using domestic wastewater as a substrate, the voltage and power reached to 0.13 V and 91 mW/m(3) in the air cathode system. Even though a relatively short HRT of 1.9 h was applied, stable effluent could be obtained by the membrane filtration system and the following air purging."

According to the news editors, the research concluded: "In addition, the short HRT would provide economic benefit in terms of reduction of construction and operating costs compared with a conventional aerobic treatment process."
