Induced Static Flotation Unit ISF - Liquid Chromatography

Apr 28, 2021 · Induced Static Flotation Unit ISF. Since the IGF was originally developed for the mining industry, the power required by the impeller needed to be sufficient to suspend solids of perhaps 0.2-0.3 mm in diameter at concentrations of 30-40% solids. As solids removal is not the dominant process in oily water treatment, solids suspension capability ...

US4782789A - Induced static flotation cell - Google Patents

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. Gas bubbles are introduced into the bottom of each gasification chamber and attract suspended contaminants and/or oil as they rise.

Induced gas flotation - Wikipedia

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 removed by a skimming device.
