FILTER ELEMENT FOR WATER LOADED WITH SOLID PARTICLES AND DISSOLVED TOXIC SUBSTANCES AND PURIFICATION SYSTEM EQUIPPED WITH SAID FILTER ELEMENT

摘要

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 (10) is a molded pervious concrete layer arranged as a partition between a lower compartment (9) and an upper compartment (11) of a treatment chamber (8), wherein the water inlet (12) opens into the lower compartment (9) and a water outlet (17) issues from the upper compartment (11). The pervious concrete filter Layer may contain one or more additives to enhance adsorptio n of pollutants, such as heavy metal ions, phosphorous, hydrocarbons or other target soluble pollutants.
