Abstract

The invention relates to a filter element consisting of a molded body of porous concrete, which element is arranged in the water stream of a purification system. In particular, the filter element () is a molded pervious concrete layer arranged as a partition between a lower compartment () and an upper compartment () of a treatment chamber (), wherein the water inlet () opens into the lower compartment () and a water outlet () issues from the upper compartment ().
