Separation of particles adsorbed on carrier material.

摘要

A method is described according to which particles present in a fluid are separated from flakes adhered thereto. According to prior art separation takes place with the help of an ultrasonic field applied to the fluid. It appeared that a better separation is achieved, if the flakes are subjected to a substantial velocity gradient. This velocity gradient subjects the particles to shearing forces causing an effective separation of the elements. Tests have shown that a pump generates such velocity gradients, that a most effective separation is achieved.
