Dissolved Oxygen (DO)
Dissolved Oxygen (DO)
Dissolved oxygen (DO) refers to the oxygen that is dissolved in water, and the amount of oxygen that can dissolve is influenced by factors such as atmospheric pressure, water temperature, and salinity. It is used as an indicator of pollution in water bodies such as rivers, lakes, and marine areas, and is measured and managed for adjusting the amount of activated sludge (clusters of microorganisms) in treatment plants and sewage treatment facilities. Additionally, it is widely measured in various industrial applications, not limited to environmental monitoring, such as boiler water and ultrapure water in the semiconductor industry.
