Mekanik Flotasyon Hücresinde Flok-flotasyonu ile Doğaltaş işleme atıksuyundan süspanse tanelerin yüzdürülmesi

Abstract

Flocculation and flotation methods have been applied individually to achieve the removal of suspended particles from wastewater. However, in this study, the floc-flotation method where these two methods are applied together in a mechanically agitated cell and the use of combinations of different type surfactant and polymer to achieve floatability of fine particles are investigated. The conventional and floc-flotation experiments were carried out to determine the effect of different parameters such as collector type and dosage, pH, flotation time, condition time and polymer/surfactant interactions on floatability of very fine particles. When the results of floc-flotation and conventional flotation were compared, it has been found that higher floatability values were achieved with floc flotation. It can be obtained 96.8% floatability of particles in presence of anionic surfactant (Aero 845, 750 g/t) and nonionic polymer (SPP N 134, 30 g/t) at pH 8 and 5 min. conditioning time for 5 min. flotation time by floc flotation in the mechanical cell.
