Induced Gas Flotation is very widely used in treating the industrial wastewater effluents from oil refineries, petrochemical and chemical plants, natural gas processing plants and similar industrial facilities. IGF Units in the oil industry do not use air as the flotation medium due to the explosion risk. These IGF Units use nitrogen gas to ...

Induced gas flotation, or 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 …

The document discusses investigating the performance of induced gas flotation (IGF) for treating produced water from oil refineries in the Persian Gulf region. The produced water has an elevated temperature of around 100°C and high total dissolved solids (TDS) of approximately 300 g/l. Pilot tests on a synthetic produced water found that at 100°C and …

The objective of this work is to study the treatment of oily wastewater containing anionic surfactant at Critical Micelle Concentration (CMC) by the Modified Induced Air Flotation (MIAF) process. MIAF, which is the combined process between the IAF process and the coagulation process, was applied and also compared with the …
The document discusses a study that investigated the use of induced air flotation (IAF) to remove polycyclic aromatic hydrocarbons (PAHs) from produced water (PW) obtained from an oilfield. The study examined the effect of varying concentrations of the nonionic collector Tween 80 and the frother ethanol on PAH removal performance. Ultraviolet-visible …
Induced gas flotation (IGF) IGF mainly adopts diffusion or porous plate to directly add compressed air to the flotation tank or with the help of a water pump suction pipe to inhale the gas. Otherwise, a bubble generator or high-speed impeller produces negative pressure to inhale gas into the floatation tank, generally forming bubbles of …

Its schematic dia-gram and dimensions are shown in Figure 1. The cy-lindrical-shaped generator has an outer diameter of 45 mm and a height of 80 mm. There are two entrances in it. The one in the ...
The Induced Air Flotation (IAF) applies a self aspirating and radially discharging funnel-shaped nozzle, which produces extremely fine gas bubbles by using only 10% of the purified waste water recycle as the propulsion jet. This nozzle is installed in a flotation cell, where intimate contact between flocs and gas bubbles takes place. ...

Induced-air flotation makes use of the centrifugal force of a high-speed backspin impeller through which gas is introduced at the top and liquid at the bottom. The gas and liquid become fully intermingled and, after passing through a disperser outside the impeller, form a multitude of gas bubbles, thus completing the flotation separation ...

Dissolved air flotation is a process that aims to separate a solid phase from a liquid phase. In the field of water treatment, the preferred term is "clarification", probably because it …
Induced air flotation (IAF) was developed using a rotating-flow microbubble generator for water treatment. This newly-developed generator can produce fine microbubbles with diameters on the order of micrometers, whereas it has to use a large quantity of water as propulsion, especially when surfactant-free water is used. That is to …
Induced air flotation (IAF) is a well-known technology that is widely applied in urban wastewater treatment plants (WWTP) for fat, oil, and grease (FOG) removal. However, most IAF systems are not optimized and typically operate with fixed parameters, regardless of inflow variations. Furthermore, the optimization of IAF systems is limited by …
