TI  - Removal of Suspended Particles from Wastewater by Conventional Flotation and Floc-flotation
AB  - n this study, the application of conventional flotation and floc-flotation methods to the wastewater containing suspended particles have been investigated. The experiments were carried out in two stages in the Jameson flotation Cell. The results obtained from the two methods were compared. The effect of flotation time and polymer type on the fine particle removal efficiency and residual turbidity was also determined. As a result of experimental studies, it was found that higher particle removal recovery and lower residual turbidity were obtained by floc-flotation compared to conventional flotation. Increasing flotation time increased fine particle floatability and decreased residual turbidity. In 1st stage of the experiments, 96.6% of the floatability recoveries and 304 NTU residual turbidity value was obtained with the combination of anionic polymer (SPP 508) and anionic surfactant (Aero 845) at the end of the 10 minutes flotation time. After 10 minutes of 2nd stage experiments, over 98% of floatability recoveries were obtained by floc flotation. The residual turbidity value of wastewater was decreased from the initial turbidity value of 12000 NTU to 78 NTU by anionic polymer, to 39 NTU by cationic polymer, and 27 NTU by a nonionic polymer.
