Principles of Air Flotation Technology | SpringerLink
Abstract. Air flotation, in all its variations, is an efficient way to separate light particulates and oils from wastewater. Particulates that adhere to an air bubble, either by adsorption or absorption, can be floated from the liquid phase. Polymers may be added to improve the attachment of the particle to the bubble.
