A backwashing alluvial filter has a vertical filter container, a plurality of collecting pipes removably mounted in the container, a plurality of filter elements suspended on the collecting pipes, separating walls subdividing the interior of the filter container into at least two chambers, and communicating with one another via vertical overflow shafts. Washing off of solid matter is performed by supplying a washing liquid via pipes directly under the overflow shafts. |
