Biochemical Oxygen Demand
(BOD) refers to the amount of oxygen that would be consumed if all the organics
in one liter of water were oxidized by bacteria and protozoa
(ReVelle and ReVelle, 1988).
BOD value is most commonly expressed in milligrams of oxygen consumed per liter
of sample during 5 days of incubation at 20°C and is often used as a robust surrogate of
the degree of organic pollution of water.
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.
