Description
Air Flotation Unit: Advanced Solution for Efficient Wastewater Purification
The Air Flotation Unit is an essential piece of wastewater treatment equipment designed to remove suspended solids, oils, and other pollutants using microbubble flotation technology. This system plays a crucial role in enhancing water quality by leveraging dissolved air to isolate and extract impurities, making it especially effective in industrial, municipal, and commercial wastewater pretreatment processes.
By introducing pressurized air into water and subsequently releasing it in a flotation tank, the Air Flotation Unit generates microscopic air bubbles that attach to contaminants, lifting them to the surface for easy removal. This process ensures a highly efficient separation of solids and oils from wastewater, resulting in cleaner effluent and more sustainable water treatment operations.
Key Functions of an Air Flotation Unit
| Function | Description |
|---|---|
| Microbubble Generation | Pressurized air dissolves in water to produce fine bubbles when released. |
| Pollutant Adsorption | Tiny air bubbles attach to suspended particles, colloids, and oils. |
| Buoyant Separation | Air-flotation bodies rise to the surface due to lower specific gravity. |
| Scum Removal | Surface scum layer is collected using mechanical scrapers. |
| High-Efficiency Clarification | Achieves rapid and effective separation of pollutants from water. |
Common Application Scenarios
Air flotation unit are widely used in sectors requiring reliable separation of oils, solids, or colloidal particles from wastewater. Typical use cases include:
Food Processing Industry
Used to treat effluent from meat packing, dairy, and seafood processing by removing fats, oils, and suspended solids before biological treatment.
Petrochemical and Refining Facilities
Separates hydrocarbons and oily substances from process water to protect downstream systems and improve water reuse efficiency.
Textile and Dyeing Plants
Removes dyes, sizing agents, and suspended particles to meet stringent discharge requirements.
Paper and Pulp Mills
Treats whitewater and removes fiber residues, enhancing clarity and reducing sludge volume.
Municipal Wastewater Pretreatment
Deployed in municipal systems to pre-treat high-load industrial or commercial waste inflows, reducing the burden on biological units.
