BOD

The role of Biochemical Oxygen Demand (BOD) is to measure the amount of oxygen needed to remove organic waste from the water of bacteria.Important to know, the larger the Biochemical Oxygen Demand, the more rapidly oxygen is depleted in the stream. This means there will be less oxygen in the water.biological oxygen demand is essential By providing information to assess the effect discharged wastewater will have on the receiving environment.The BOD value is commonly expressed in milligrams of oxygen consumed per liter of sample during 5 days of incubation at 20°C.The goal is maintaining the aquatic life and aesthetic quality of streams and lakes.

Biological Oxygen Demand (BOD)

Applications of Biochemical Oxygen Demand:

Study of Biodegradability & Toxicity of organic compound.
Study of reaction kinetics biodegradation of specific waste and its removal from the environment.
Study of specific bacterial strength and enzymatic systems responsible for biodegradation of specific compound.
Study of oxygen up take rate of biomass and their viable concentration present in activated sludge systems.
Monitoring of the performance of effluent treatment systems with greater speed and reliability.
