SubscribeMany gases mix with water like nitrogen and oxygen without chemically reacting with it.
Some gases chemically react with water e.g. ammonia, CO2, and HCl. Oxygen does not react with water. Dissolved Oxygen (DO) is really a physical distribution of oxygen molecules in water.
There are two main sources of DO in water: atmosphere and photosynthesis. Waves and tumbling water mix air into water where oxygen readily dissolves until saturation occurs. Oxygen is also produced by aquatic plants and algae as a by-product of photosynthesis.

How Can Dissolved Oxygen be Measured?
Dissolved Oxygen can be measured in the laboratory using a bench DO Meter, in outdoor and field applications a portable DO Meter would be used and for plant and process applications an online DO controller would be used. Dissolved Oxygen can be measured using the Polarographic (Clark Cell) Method or the Galvanic Cell Method.
