Biological Oxygen Demand Sensor Using an Arsenic Resistant Bacterium

Analytical Sciences, 1990
Various microbial biosensors, including BOD (biological oxygen demand) sensors, have been reported.''2 These are usually constructed by holding intact microorganisms, such as bacteria and yeasts, near the tip of an oxygen electrode. Since microorganisms consume organic compounds quantitatively, their concentrations can be determined by estimating the ...

Ability of local species plant in surface flow constructed wetland to reduce biochemical oxygen demand (BOD) and chemical oxygen demand (COD) in sasirangan wastewater

, 2020
Sasirangan wastewater has characteristics of high pH as well as high level of biochemical oxygen demand(BOD)and chemical oxygen demand(COD). Sasirangan industries produce large amount of wastewater, which then is directly discarded around the environment
