Beschreibung
Zusammenfassung:	The filter (9) material (13) comprises synthetic or natural crystallized hydrated aluminosilicates having a structural framework containing ions of alkali- or alkaline earth metals. The filter is directly connected to a roof drainpipe (2). Preferred features: The filter is a zeolite compound. Adsorbents are added to it. It is located in the standpipe (5) of the roof drain, above ground (6) level. It comprises a double-walled (10, 11) cylindrical cartridge enclosing an annulus (12) containing filter material. Lower ends of the tubes are turned to overlap one another, a ring spacer is inserted into the annulus at the top. Above the filter is a water distributor. Low down, a collector includes a trap for foreign bodies. Water storage with pumped distribution through the filter are included. The filter is inserted in a pressure vessel. The storage vessel includes level control. Further detail based on the foregoing principles is described.
