Induced Gas Flotation

Induced gas flotationWikipedia

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 water where it may then be

Sep 12, 2013· Induced gas flotation (IGF) is a treatment process that clarifies wastewaters (or other waters) by the removal of suspended oil. The removal is achieved by introducing very small bubbles of air or other gases into the water or wastewater. The bubbles adhere to and enhance the buoyancy of the suspended oil which accelerates the rate at which the oil floats to the surface of the water where it can

TECHNICAL PAPER Induced Gas Flotation (IGF) within

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

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.

the injection of air or production gas using water as the driving fluid through the injector nozzles. Under these conditions, the flotation kinetic is similar to a process of Dissolved Air Flotation (DAF) but with less energy consumption, similar to the Induced Air Flotation (IAF) process. This system, as well as being efficient, is also
