Abstract

The liq. is conducted vertically, the mean flow speed during the entire treatment being maintained so that all particles are entrained forwards, the residence time in the vertical flow being sufficient for the differences in the flow speeds of particles to result in particles combining and growing; sepn. is then effected out in a later treatment stage. Pref. the vertical flow follows alternate upward and downward directions, the flow speed in both directions exceeding the natural settlement or flotation speed of the particles. In the horizontal connections between these vertical limbs of the path, the speed is also sufficient to prevent the particles sepg. out.
