Experimental Investigation Of Bubble Size In Flotation
Flotation was conducted in two cells (1.5 and 2.5 m) with microbubbles (MBs, 5–80 μm) and nanobubbles (NBs, 50–300 nm diameter, concentration of 10 8 NBs mL −1). Bubbles were formed using a centrifugal multiphase pump, with optimized parameters and a needle valve.Apr 21, 2010 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.
