A Historical Perspective on Produced Water Treatment
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.

Process
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).

Gas Flotation
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 …
