Introduction to Air Flotation Machine Equipment
In the field of wastewater treatment, the air flotation machine is a highly efficient solid-liquid separation device. It operates by introducing a large number of microbubbles into the water, which attach to suspended particles. Leveraging the principle of buoyancy, these particles float to the water's surface, enabling solid-liquid separation and effectively removing impurities, suspended solids, and certain dissolved contaminants from the wastewater.
Working Principle
The air flotation machine operates primarily based on the principle of dissolved air flotation (DAF). Under specific pressure, air is dissolved into water through a dissolved air system to form saturated dissolved air water. When the dissolved air water is abruptly depressurized via a release device, the supersaturated air in the water is released as microbubbles, typically measuring 20–40 micrometers in diameter. These microbubbles rapidly adhere to pollutants such as suspended particles, colloids, and emulsified oil droplets in the wastewater, reducing the overall density of the pollutants below that of water. As a result, buoyancy causes the pollutants to float to the water surface, forming a scum layer, which is then scraped off by a scum removal device to achieve solid-liquid separation. The purified water is discharged from the bottom of the equipment.

Application Scope
Domestic Sewage Treatment
As a pretreatment device for domestic sewage, it can effectively remove impurities such as suspended solids and floating matters, reduce the load on subsequent biochemical treatment units, and improve the overall treatment efficiency of sewage treatment plants. It can also be used for sludge thickening to reduce sludge volume, facilitating subsequent sludge transportation and disposal.
Water Supply Treatment
For raw water such as lake water and river water, it performs algae removal and turbidity reduction treatment, eliminating algae, plankton, and suspended particles in the water. This can purify the turbidity of domestic drinking water and industrial water to below 5 degrees, while also effectively reducing colority and oxygen consumption, ensuring the safety of water supply quality.
