Abstract

The sand filling is located between vertical water-permeable limit walls of a drain chamber. The channels supplying water to be filtered are arranged outside the filter while the drain chamber collecting the filtered water is located inside the filter. The filter walls are water-permeable all over their height, the collecting ring for drawing off water is mounted in the lower part.
