The feed stream, after saturation with dissolved air, is introduced into the flotation cell. The flow spreads uniformly across the tank. The micro air bubbles adhere to the suspended particles creating a floating action on these particles. A thick blanket is formed by the solids at the surface of the cell.Get In Touch
