1 Pre-preparation of Dissolved Air Water
The operation of a dissolved air releaser relies on dissolved air water as a basic condition.
Process: Under specific pressure, the water pressure is increased using pressurization equipment, forcing air into the water to form saturated dissolved air water.
- This process requires ensuring sufficient contact between the water and air, controlling the water temperature and air purity to reduce impurity interference.
- Ensuring that gas molecules are evenly dispersed between water molecules provides sufficient dissolved gas reserves for subsequent release stages.
- This stage is a prerequisite for the entire air flotation separation system, establishing the foundation for efficient bubble generation.
2 Precise Control of Pressure Environment
The core function of the dissolved air releaser is to change the pressure state of the dissolved air water.
Mechanism: After the dissolved air water enters the releaser, the environmental pressure is rapidly and smoothly reduced through a specific flow channel design optimized by acoustics and fluid mechanics.
- This sudden pressure drop disrupts the original dissolution equilibrium, creating conditions for bubble precipitation.
- The design prevents uneven bubble precipitation caused by local pressure fluctuations while maintaining system stability.
- This pressure change causes excess air in the water to lose its dissolving carrier, initiating the bubble formation process.
3 Efficient Generation of Microbubbles
As the pressure decreases, the air dissolved in the water gradually gathers and precipitates.
Technology: The release device utilizes special components made of corrosion-resistant, high-strength materials with precise pore or channel design to control bubble size.
- The design cuts and disperses the released gas into tiny, uniform microbubbles with extremely small diameters.
- These microbubbles have large specific surface areas and excellent suspension properties in water.
- They do not aggregate into large bubbles due to water flow impact and can remain stably suspended in the water column.
4 Achieving Air Flotation Separation
The generated microbubbles float freely in the water, utilizing intermolecular forces to fully contact and efficiently adsorb suspended impurities and pollutants.
Separation Process: Microbubbles carry impurities to form an air-float mass with a density less than water, continuously rising to the surface.
- Even fine suspended particles that are difficult to settle can be captured by these small-diameter bubbles with large specific surface areas.
- The rising microbubbles form scum on the water surface, which is then separated and removed by a skimmer device.
- This process significantly improves the efficiency and effectiveness of water purification systems.
