Abstract
Treatment of fluid polluted with solid particles, for instance, from a dust removal or washing process, by pretreating the fluid to agglomerate the particles, then whirling the fluid to centrifugally concentrate the particles in a first fraction of the fluid and thereby substantially purifying a second fraction thereof, filtering the first fraction to recover the solid particles, collecting the particles and recirculating the purified fluid in the particle removal or washing process, the above treatment being carried out by apparatus having particular utility where the fluid is a liquid.
