Get PriceFlotation: DAF, IAF, SAF By Dave Christophersen, Vice President/Technical Manager Flotation is a method of separating solids or liquids from water by introducing fine gas bubbles. The bubbles attach to the particulate matter, and the buoyant force of the combined particle and gas bubbles is great enough to cause the particle to rise to the surface.

In wastewater treatment, the advantage of flotation over sedimentation includes: x When the stream is variable and th ere is a tendency for some of the particles to rise or oil is presen t, a sedimentation process could be compromised as some of the waste naturally floats to the surface.
Get Priceflotation process, in mineral treatment and mining, process for concentrating the metalbearing mineral in an ore . Crude ore is ground to a fine powder and mixed with water, frothing reagents, and collecting reagents. When air is blown through the mixture, mineral particles cling to the bubbles, which rise to form a froth on the surface.
Get PriceMicroflotation is a further development of standard dissolved air flotation (DAF). Microflotation is a water treatment technology operating with microbubbles of 10–80 μm in size instead of 80300 μm like conventional DAF units. The general operating method of microflotation is similar to standard recycled stream DAF units.

Historically this was first used in the mining industry, where it was one of the great enabling technologies of the 20th century.
Get PriceThe process is initiated when oily wastewater enters the EnviroCell™ at the inlet. The inlet cell provides a surge capacity, dampening the incoming flow, allowing the flotation process to properly function. It also provides a buffer for free oil removal and skimming, lowering the oil content of the process before entering the first active cell.
