Chang, IS Jang, JK Gil, GC Kim, M Kim, HJ Cho, BW Kim, BH 2024-01-21T07:39:26Z 2024-01-21T07:39:26Z 2021-09-02 2004-01-15 0956-5663 https://pubs.kist.re.kr/handle/201004/137927 A mediator-less microbial fuel cell (MFC) was used as a biochemical oxygen demand (BOD) sensor in an amperometric mode for real-time wastewater monitoring. At a hydraulic retention time of 1.05 h, BOD values of up to 100 mg/l were measured based on a linear relationship, while higher BOD values were measured using a lower feeding rate. About 60 min was required to reach a new steady-state current after the MFCs had been fed with different strength artificial wastewaters (Aws). The current generated from the MFCs fed with AW with a BOD of 100 mg/l was compared to determine the repeatability, and the difference was less than 10%. When the MFC was starved, the original current value was regained with a varying recovery time depending on the length of the starvation. During starvation, the MFC generated a background level current, probably due to an endogenous metabolism. (C) 2003 Elsevier B.V. All fights reserved.
