How to make a good solution even better?
AGA oxygenation cones ensure oxygenation of the water that flows through them by adding oxygen under pressure. This design ensures that close to 100% of the oxygen is dissolved. The outlet water is saturated with oxygen, but free of bubbles. The un-dissolved oxygen is not released from the cone. This prevents bubbles and pockets of gas in the pipe system.
Even with almost 100% efficiency there is oxygen to spare
The flow of water is moving at its fastest when it is fed into the top of the cones. This is where the oxygen is dissolved most quickly. The water flows more slowly further down in the cone as the cross-section increases, and the oxygen forms bubbles which result in slower dissolving. Some bubbles grow so large that they rise and form an area of gas right at the top of the cone.
The solution was quite simply on the surface
The area of gas at the top of the cone appears when the bubbles of gas rise and collect at the top of the cone. This results in a small contact surface between the water and the oxygen, and hence a slow mass transfer rate. The SOLVOX® CV resolves this issue easily and effectively: the oxygen from the gas pocket at the top of the cone is recirculated.
