Micro nano bubble technology can significantly improve the solubility of ozone, which can be achieved from the following aspects:

1、 Increase contact area

Micro nano bubbles have extremely small diameters and a larger specific surface area than traditional bubbles. This significantly increases the contact area between ozone and water. A large number of ozone molecules can come into contact with water more fully, thereby increasing the chances of ozone dissolution. For example, in the same volume of water, the number of micro nano bubbles can reach millions or even more than traditional bubbles, greatly increasing the number of contact sites between ozone and water.

2、 Slow rise and long dwell time

Micro nano bubbles rise very slowly in water, and some can even remain suspended in water for a long time. This allows sufficient time for ozone to fully interact with water, increasing the time window for ozone dissolution. Unlike traditional bubbles that quickly rise and escape from the water surface, micro nano bubbles can stay in water for a longer period of time, providing a more stable environment for the dissolution of ozone.

3、 Rupture effect

When micro nano bubbles rupture, instantaneous local high temperature and high pressure will be generated. This energy release can promote the faster dissolution of ozone molecules into water. At the same time, during the rupture process, strong oxidizing substances such as hydroxyl radicals will also be generated, which can work synergistically with ozone to enhance the oxidative degradation ability of pollutants in water and further improve the utilization efficiency of ozone.

4、 Enhanced gas-liquid mass transfer

The presence of micro nano bubbles can alter the physical properties of water, reduce its surface tension, and promote gas-liquid mass transfer processes. Ozone is more easily transferred from the gas phase to the liquid phase, increasing the solubility of ozone. In addition, the water flow state around micro nano bubbles will also change, forming local flow phenomena such as micro eddies, further enhancing the gas-liquid mass transfer effect.

5、 Optimize usage conditions

In practical applications, the dissolution effect of ozone can be optimized by adjusting the parameters of the micro nano bubble generation device, such as bubble size, generation rate, gas flow rate, etc. Meanwhile, by combining appropriate stirring and temperature control measures, the solubility of ozone can also be further improved. For example, increasing the gas flow rate within a certain range can improve the supply of ozone, but excessively high flow rates may cause bubble coalescence and reduce the effectiveness of micro nano bubbles. Therefore, parameter optimization needs to be carried out based on specific experimental conditions.
