Abstract

Liquid flows from a bottom inlet to a tank in which it is stirred by an impeller, rotating at such a speed that a vortex is formed, and entrains air, which induces flotation of solid partiles. Particles are removed with similar efficiency to that of a filter, but process is continuous as no clogging occurs; and oxygenation of liq. is maintained thus obviating fermentation. The impeller shaft may be grooved etc. to assist entrainment, but hollowing for air feed to liq. is not necessary.
