Zonal Density Gradient Reorientation

Particles are separated by buoyant density using a reorienting gradient.

Zonaldensity gradient reorientation

Step Process
1 While at rest the rotor is filled, using a pump, with density gradient material.
2 During rotor acceleration the density gradient reorients vertically inside the rotor.
3 Once at operating speed, product fluid containing the vector particles is pumped into the rotor.
4 Vector particles begin to sediment radially and band isopycnically in the gradient. Waste material flows out of the rotor.
5 After the product fluid is processed, the rotor is decelerated and brought to a stop. The gradient reorients horizontally while retaining particle separation.
6 With the rotor now at rest, the desired separated particles are now ready to be collected.
