Question

Difference between biological oxygen demand and biochemical oxygen demand

Answer 1

Answer:

Practically biological oxygen demand and biochemical oxygen demand are the same. It is the amount of dissolved oxygen required by aerobic biological organisms to break down organic material in a water sample. Difference can be stated between biological oxygen demand (BOD) and chemical oxygen demand (COD).

Answer 2

Biochemical oxygen demand is the amount of dissolved oxygen needed by aerobic biological organisms to break down organic material present in a given water sample at certain temperature over a specific time period

BOD is a measure of, the amount of oxygen that require for the bacteria to degrade the organic components present in water / waste water.
