The possibility of using BOD on-line measurement.
Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
BOD (Biochemical Oxygen Demand) is one of the important parameters in wastewater treatment technology, it normally takes five days to get the result. Using MFC (Microbial Fuel Cell) to build up a small on-line system to measure BOD will reduce to operating time to 20 minutes. In this report, the MFC BOD on-line measurement was processed in order to test if this rapid way would work in practical usage.
The experiment used secondary sedimentation sludge as the bacteria source on the MFC anode pattern with GGA (Glucose and Glutamic Acid solution) as an electron producer, and the 30 minutes voltage value changing curves was gotten by measuring the voltage. At the end the curve was analyzed and compared with the real BOD value in order to get the conclusion.
The BOD on-line measurement is quite promising and efficient when multi-samples are needed to be tested.
