Flotation: 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.
Induced air (gas) flotation separators operate by inducing air bubbles into a chemically treated water stream. The the air bubbles, which then rise to the surface and are skimmed off. Quadricell Separator Operation The Quadricell® separator operates on a low energy, low capital cost, mechanical air (gas) induction principle to
Flotation Separation Technology Induced air (gas) flotation separators operate by inducing air bubbles into a chemically treated water stream. The chemicals cause the contaminants to attach themselves to the air bubbles, which then rise to the surface and are skimmed off. Induced air flotation technology offers exceptional efficiency
An induced static flotation (ISF) cell has an inlet chamber, a plurality of gasification chambers, and an outlet chamber. Contaminated liquid enters the inlet chamber, passes through the gasification chambers, and exits through the outlet chamber.
An inducedgas flotation cell made according to this invention includes an elongated, horizontally oriented separator vessel 10 of a kind used in the art and having a produced water inlet 11 at its first end 13 and an oil outlet 15 and a water outlet 17 located at its second end 19.

Here is a page about the invention of froth flotation as it appeared in a 1917 . That is the basic design of a single froth flotation cell and how it works. Contact US Induced gas flotation . Induced gas flotation (IGF) is a water treatment process that clarifies wastewaters (or other .
Induced Gas Flotation (IGF) has been used for Produced Water (PW) treatment for decades. The roots of flotation technology are in mining, where it has been used to enrich metal ores since the late 1800s. The technology has evolved somewhat to better suit the special limitations presented by offshore facilities.
Induced Gas Flotation D.04 Introduction Induced Gas Flotation (IGF) is a wellproven method of oil recovery in water treatment applications. IGF Units are used extensively around the world for the recovery of oil from produced water streams in a wide range of applications at onshore and offshore production and processing facilities,
A flotation cell is the primary unit operation used to recover fine oil droplets from produced water systems. Both mechanical induced gas flotation (IGF) and hydraulic dissolved gas flotation (DGF) cells have been used for residual oil removal from produced water since the late 1960s (Sport 1970Bassett 1971).
The Tridair Hydraulic Induced Gas Flotation Cell typically accomplishes up to 9098% removal of insoluble oil/organic and suspended solids. Removal efciency is inuenced by physical characteristics of the incoming stream such as pH, total dissolved and suspended solids, temperature, presence of chemicals, mixtures of different streams
Hydraulically Induced Gas Flotation Hydraulic IGFs replace the mechanical driver at each cell with a single circulation pump for several cells. Clean water, taken from the last cell, is injected into each cell through a nozzle designed to create a venturi effect (vacuum).
Induced gas flotation cell The flotation process for removing suspended materials from produced waters is widely used in the petroleum industry to improve the water quality . Flotation involves the introduction of gas or air into the water to create a foam or froth which will scrub the solids from the liquid and carry them out with the foam.
Induced Gas Flotation A Frames Induced Gas Flotation Unit (IGF) receives water from the CoalescingPlateSeparator (CPI), as well as an additional stream from the second stage separators and dehydrators. Water from the CPI still contains dissolved gas, which will be used in the IGF vessel for gas flotation.
FLOTATION SEPARATION TECHNOLOGY Induced air (gas) flotation separators operate by inducing air bubbles into a chemically treated water stream. The chemicals cause the contaminants to attach themselves to the air bubbles, which then rise to the surface and are skimmed off. Induced air flotation technology offers
Induced Gas Flotation (IGF) and Induced Static Flotation (ISF) units provide a more enhanced approach to oil removal through the addition of gas bubbles to aid in the flotation of oil to the surface. Gas, which is typically induced by sparging tubes or eductors, floats the oil to the surface, which can then be skimmed off. In addition
