Biochemical oxygen demand (BOD) is the amount of oxygen microorganisms require to break down organic materials. In contrast, chemical oxygen demand (COD) is the amount of oxygen required to break down the organic material via oxidation
BOD stands for Biological Oxygen Demand, while COD stands for Chemical Oxygen Demand. These two measurements are used to determine the amount of oxygen that is required to break down organic matter in water.
BOD is a measure of the oxygen that is consumed by microorganisms as they break down organic matter in water. It is typically used to assess the quality of water, particularly in rivers and streams, and is expressed in milligrams of oxygen per liter of water (mg/L).
COD is a measure of the oxygen that is consumed by chemical reactions as organic matter is oxidized. It is typically used to assess the amount of organic matter present in water, and is expressed in milligrams of oxygen per liter of water (mg/L).
Both BOD and COD are important indicators of the health of aquatic ecosystems, as they provide information about the amount of organic matter present in the water, which can affect the ability of the ecosystem to support aquatic life. However, they are different in terms of the processes they measure and the types of organic matter they can detect. BOD measures the oxygen consumed by microorganisms as they break down biodegradable organic matter, while COD measures the oxygen consumed by chemical reactions as all types of organic matter are oxidized.
