Zusammenfassung
Column-shaped tubes of plexiglass filled with granular activated carbon have been tested with regard to the interstitial biological process of purification of infiltrating raw water. Four columns (diameter: 140 mm; high: 1.5 m) have been combined to form a communicating experimental set. These sets were installed in the waterconditioning plant in the Municipal Waterwork of Bremen on the River Weser (Fig. 1). In the course of biological investigations the interstices of activated carbon proved to be artificial biotopes for organisms previously known especially from biocoenoses in interstitial waters and other "hiding-place biotopes" ("Schlupfwinkelbiotope", Husmann & Teschner 1970) of limnic and marine ecosystems, respectively (Figs. 3 and 4). Marine and limnic organisms exist in the activated carbon filters. This is favoured by the salinity of the water in the River Weser (Fig. 2) which is used as raw water in the drinking-water conditioning plant of Bremen.
