2. Dissolved Gas Flotation Section Water enters the unit through lotation section and lows down the length of the vessel through four lotation cells. Each lotation cell is separated from the next by an underlow bafle which is designed to maintain uniform low through the lotation cell. The recycle stream is taken from treated water section
Polishing afterwards with Dissolved Gas Flotation units best, especially when pressure is available – Mother Nature's superior Induced Gas Flotation method; Further filtration downstream may be required to meet more stringent …
Primary (1st stage) treatment uses hydrocyclones (desanders and deoilers) to remove the bulk of solids and liquids. This technology will separate down to 10 micron sand particle size and 30-40 ppm oil content. Second stage treatment is most commonly induced gas flotation (IGF), followed by nut shell media filtration (NSF).
The bottom (red) line shows the range of operation for a WH4 (4" diameter) desander. At 5 psi pressure drop the unit has a throughput of ~1100 BPD, while at 50 psi pressure drop the throughput increases to slightly less than 4000 BPD.
The next article covers the general design and operation of the multiphase desander. References. Rawlins, C.H. 2017. "Separating Solids First – Design and Operation of the Multiphase Desander", paper 185658-MS presented at the SPE Western Regional Meeting, Bakersfield, CA, 23-27 April.

Two IGF methods, similar in principle but different in design, were in use: the mechanical IGF and the hydraulic IGF. The efficiency of the hydraulic design closely followed that of the mechanical design, but has gradually improved over the past 30 years. Outside of the first Monosep multicell IGF, WEMCO also created a hydraulic nozzle air design.
Produced water is a major byproduct in oil production and the largest waste stream generated in the petroleum industry. At the Norwegian Continental Shelf, produced water is still mostly discharged to the sea, but …
Gas flotation for oily wastewater treatment is based on the attachment of gas bubbles to oil droplets to produce lighter aggregates that rise to the wastewater surface.
API and CPI (Corrugated Plate Interceptor) separators are predominantly used in the separation of free oil from produced or effluent water or suspended solids for oily water treatment in an (Oily Water System) (OWS).

Induced Gas Flotation (IGF) 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 injecting gas bubbles into the water or wastewater in a flotation tank or basin. The small bubbles adhere to the suspended matter causing the suspended matter to float to the surface of the …
