New Microbubble Method for Dissolved Air Flotation
The main aim of this PhD project is to investigate the effectiveness of a new method of microbubble production using a dissolution type microbubble generator for Dissolved Air Flotation (DAF) in water treatment. The hope is that the new method will enhance the energy efficiency of the separation process.

water treatment – floatability and rising velocity
In the water treatment field, it is customary to use the term of flotation (in the strict sense) exclusively for flotation induced by using microbubbles similar to those found in "white water" delivered by a tap on a water main rich in gas dissolved under high pressure. This process is called dissolved gas flotation ( DAF).

Flotation: DAF, IAF, SAF - Water and Wastewater Treatment
Typically a recycle flow of the DAF effluent is returned to a pressure tank where the air is added and the tank is pressurized to 50 – 75 psig. The recycled water is mixed with raw influent allowing intimate contact to occur with the released bubbles and the influent particles.

water treatment – natural flotation and aided flotation
When treating oil field water (water withdrawn from an oil well with the hydrocarbons), separating out the oils by mechanical flotation is also designated foaming. This separation is carried out by mixing air (or natural gas) into the water to be treated after it has been processed by adding an organic coagulant and/or a demulsifying agent.

Dissolved air flotation (DAF) 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 dissolving air in the water or wastewater under pressure and then releasing the air at atmospheric pressure in a flotation tank basin.
