Application of micro-nano bubbles for oil-water separation

The trajectory of the micro-nano bubbles in the water is not straight up, but a slow rise in lateral motion. It takes 4 to 5 hours on average to rise 1 meter. The trajectory of the lateral movement and the long-term stay in the water allow the bubbles to capture oil droplets. Create plenty of time. Because the micro-nano bubbles are very small, they have the same surface energy as the tiny particles of any object, and they have surface adsorption for other objects. Coupled with the electrification function of some bubbles, they can also adsorb gas objects, so oil can be adsorbed in oil-contaminated water. Droplets and other pollutants make tiny oil droplets gradually aggregate into larger oil droplets and quickly rise to the water surface to complete the oil-water separation of oil-contaminated water.
