In many applications in water and wastewater treatment, biotechnology and food processing, the flotation of small colloidal matter is best carried out by utilizing small bubbles in the size range of 20 to 100 microns in diameter (Matis and Zouboulis, 1995). Small bubbles also work quite effectively in the removal of near-neutrally buoyant emulsified contaminants, where the use of conventional treatment techniques such as sedimentation or centrifugation results cost-intensive (Pushkarev et al., 1983). In practise, such small bubbles are generated by dissolved-air or electrolytic methods, and the technique has been termed microflotation (Rubin et al., 1966).  2, record 1, English, - microflotation
