Technical Field

[0001] The utility model relates to the technical field of air flotation devices, in particular to dissolved air flotation slag removal equipment. Background Art

[0002] A flotation device is a device that uses gas buoyancy to suspend an object. Common applications include suspended liquid treatment in industrial production processes, sewage treatment, wastewater treatment, and cleaning of floating objects at sea. A flotation device usually includes a buoyancy chamber and a gas supply system.
