Sending a thin water film to under direction.
Sending a countercurrent air flow and Oxygen is absorbed into the water.
Measuring Mass transfer coefficient.
Vapor-liquid mass transfer device
Means of basic experiment for understanding the mass transfer phenomena
Dissolved Oxygen is the state of oxygen molecules dissolved in the water or a solution.
At the state of 20℃ and 1atm, DO reaching the saturated state at 9ppm
DO decrease the temperature rises, and increase the air pressure rises
