Dissolved air flotation Wikipedia

Dissolved air flotation (DAF) is a water treatment process that clarifies wastewaters (or other waters) by the removal of suspended matter such as oil or solids. The removal is achieved by dissolving air in the water or wastewater under pressure and then releasing the air at atmospheric pressure in a flotation tank basin. The released air forms tiny bubbles which adhere to the suspended matter

What’s a flotation tire? TireBuyer

Flotation tires often have a particularly wide footprint, which can be maximized by running with lowered tire pressure and expanding the (very durable and reinforced) tire sidewalls. Rather than digging and clawing through the terrain like certain types of off-road tires, flotation tires conquer difficult loose terrain primarily by expanding

Buoyancy Wikipedia

Buoyancy (/ ˈ b ɔɪ ə n s i, ˈ b uː j ə n s i /) or upthrust, is an upward force exerted by a fluid that opposes the weight of a partially or fully immersed object. In a column of fluid, pressure increases with depth as a result of the weight of the overlying fluid. Thus the pressure at the bottom of a column of fluid is greater than at the top of the column.
