TECHNICAL PAPER Induced Gas Flotation IGF within an API

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 oil to the surface, which can then be skimmed off. In addition to the gas, a notable benefit to the IGF design is the

Dissolved Air Flotation DAF AWC Water

The 50 micron bubbles used for flotation are formed by recycling a small stream of clarified water through an air pressurized, packed tower saturator to specially designed nozzles at the DAF cell inlet. Here, a rapid pressure drop causes the aire out of the solution and form millions of small bubbles, which are then dispersed through the flocculated raw water. Then, the bubbles rapidly
