<p>In a method for cleaning rubble, in which the dirty water is to be purified, after the removal of relatively coarse and medium sand fractions, the invention proposes the use of a separator (7), known from the food sector and furnished with blades, to separate fine sands and very fine sands. Flotation units (12) or sedimentation units (25) can be connected downstream of the separator in order to remove the remaining contaminants from the water. As a result of the removal of the fine sand portions, the proportion of reusable substances which are removed from the water is increased, while at the same time, the proportion of wastes to be disposed of is reduced. <IMAGE></p> |
