504

The Online Microbial Fuel Cell (MFC)-type BOD Analyzer, HABS-2000, is continuous and automatic BOD measuring equipment that uses MFC, which is the first source technology in the world. Because HABS-2000 uses microbes from the field, it has outstanding field applicability, and it has less clogging due to the use of a large tubes. It is also economical and easy to maintain because there are no consumables that must be periodically replaced.

Principle

HABS-2000 can measure Biochemical Oxygen Demand (BOD) by using MFC. The MFC that is applied in HABS-2000 uses organisms or a part of them to convert the reducing power that is generated by organisms’ energy metabolism into electrical energy. Because the amount of electrical signal that is generated from MFC increases in proportion to the concentration of organic matter contained in the measuring sample, the equipment converts this to BOD concentration for measurement.
