Air flotation equipment uses microbubbles to separate other insoluble liquids (such as oil) and fine solid particle suspensions in the liquid. The fine bubbles sent through the outside of the container and the fine bubbles generated in the water due to pressure release cause them to adhere to solid or liquid particles in the wastewater that have a density close to that of water during the floating process, resulting in a state where the overall density is smaller than that of water. , and rely on buoyancy to rise to the water surface, thereby achieving the purpose of separation.1. Compact structure and small footprint; 2. The microbubbles produced are small and uniform; 3. The air flotation container is a static pressure container and has no transmission mechanism; 4. Easy installation, simple operation, and easy to master; 5. Use the internal gas of the system and do not require external gas supply; 6. The effluent water quality is stable and reliable, the effect is good, the investment is small, and the results are quick; 7. The technology is advanced, the design is reasonable, and the operating cost is low; 8. General oil field degreasing does not require chemicals Pharmacy etc.The work of air flotation equipment mainly relies on the surface of suspended matter, which is divided into hydrophilic and hydrophobic. Air bubbles tend to adhere to the surface of hydrophobic particles, so air flotation can be used. Hydrophilic particles can be made hydrophobic by treatment with appropriate chemicals. In the air flotation method in water treatment, flocculants are commonly used to form colloidal particles into flocs. The flocs have a network structure and can easily trap air bubbles, thus improving the air flotation efficiency. Furthermore, if there are surfactants (such as detergents) in the water, they can form foam and also have the effect of attaching suspended particles and rising together.
