An alternative method of flotation is "dissolved-air flotation" (DAF), which is much more common in water treatment than induced-air flotation. In DAF, a stream of water is saturated with air at an elevated pressure of the order of 4 atm. The stream is injected into a tank, but customarily there is a continuous flow of the process water ...

Deep compaction using vibro-flotation
For vibro-compaction non-cohesive soil is compacted using a vibroflot. The vibroflot is mounted on the lower end of a pipe on a lift crane, duty cycle crawler crane or rig, either free hanging on ropes or via a leader and sunk into the ground. Through the vibration the soil grains change from their initial loose layering to a denser layering.

HUBER Dissolved Air Flotation Plant HDF
Principle of Flotation: During dissolved air flotation, very fine gas bubbles of 20 ‒ 40 μm are released, which together with the particles present in the wastewater, form an agglomerate. This agglomerate has a lower density than water and rises to the water surface. Nonflotatable particles are separated via conical selection chambers.
