Micro-Bubble Air Flotation Units
Micro-Bubble Air Flotation Units
Micro-bubble air flotation units are advanced water treatment systems that use tiny air bubbles to remove suspended solids, oils, and other contaminants from water.
How They Work
- Micro-Bubble Generation: These units generate micro-bubbles, typically ranging from 10 to 50 micrometers in size. The small size of the bubbles increases the surface area for attachment to contaminants.
- Flotation Process: The micro-bubbles attach to suspended particles in the water, reducing their density and causing them to float to the surface. This process is known as flotation.
- Separation and Removal: The floated particles form a froth layer on the surface, which is then removed by a skimmer. The clarified water exits the unit as treated effluent.
Applications
- Wastewater Treatment: Micro-bubble air flotation units are widely used in municipal and industrial wastewater treatment plants to remove suspended solids, oils, and greases.
- Drinking Water Treatment: They are also used in drinking water treatment to remove turbidity and improve water quality.
- Industrial Processes: These units are employed in various industries, such as food processing, chemical manufacturing, and oil refining, to treat process water and wastewater.
Benefits
- High Efficiency: The small size of the micro-bubbles allows for efficient attachment to contaminants, resulting in high removal rates.
- Energy Savings: These units typically consume less energy compared to traditional dissolved air flotation (DAF) systems.
- Compact Design: Micro-bubble air flotation units are often more compact, requiring less space for installation.
Examples
- ENADAF Micro Bubble Flotation Unit: Designed by Endemic Process Engineering, this unit offers high removal efficiency for suspended solids, oils, and organic pollutants, with energy savings of up to 30% compared to traditional systems.
- Nanobubble Generators: These generators produce micro-bubbles for various applications, including water treatment, by operating at lower pressures and consuming less energy.
Micro-bubble air flotation units represent a significant advancement in water treatment technology, providing efficient and cost-effective solutions for various applications.
