<p>Fluid mass is divided into streams each of which undergoes successive compression and decompression movements. One stream is in compression when the next is in decompression and vice versa. Inverse displacements of the streams, thus produced cause beating of the agglomerates to be dispersed. Preferably the fluid is water, to which a thickening agent or a foam and an adhesive is added. The agent is a magnetic powder. Apparatus is described.</p> |
