Improved technology and a vertical vessel design reduce the footprint required for this innovative flotation system. The Spinsep flotation system can be designed as an ASME code or a non-code vessel.

How it Works

As the influent stream enters the Spinsep vessel, it flows through a centrifugal coalescing device (Spiralsep™ system) installed in the inlet piping to the vessel. This component initiates gravity separation of the incoming liquid and, if necessary, mixes incoming flotation aids such as chemical water clarifiers.

The circular motion created in the Spinsep vessel by the 90-degree inlet angle results in greater path distance the liquid must travel resulting in improved removal efficiency. The Spiralsep system also stimulates gas bubbles and oil droplet attachment. 

Oil droplets grow on the surface of the pack medium until gravity brings them to the surface where they are skimmed into the oil bucket. 

Water flowing through the gas flotation zone below the packing scrubs it clean of attached oil.  These droplets rise to the surface and are skimmed with incoming free oil.
