The micro nano bubble generator can play a very important role in oil-water separation, which is mainly achieved through the following aspects:

1. Enhance oil-water separation effect: The surface of micro nano bubbles has a negative charge, which can adsorb oil droplets in water, causing them to aggregate and form larger oil droplets, making them easier to separate.

2. Improve separation speed: Micro nano bubbles can quickly rise to the water surface, bringing oil to the surface and accelerating the speed of oil-water separation.

3. Reduce medication usage: Through the action of micro nano bubbles, oil-water separation can be achieved at lower medication usage, reducing costs and minimizing environmental impact.

4. Improving water quality: Micro nano bubbles can remove suspended solids and impurities from water, improve water quality, and make the water after oil-water separation clearer.
