How is bod measured in wastewater
WebThe BOD of a sample of sewage is usually determined at a temperature of 20°C. However, BOD of a sample of sewage may also be determined at a temperature other than 20°C … WebBOD is an abbreviation for “biochemical oxygen demand.” This term is used to describe the amount of oxygen that is required to break down organic matter in water. The higher the BOD level, the greater the pollution present in the water. This makes it an important indicator of water quality.
