Abstract
A filler and a process for producing it, where the filler, in the case of the biological treatment of sewage, should in particular exhibit a "biological meadow" which is necessary for this purpose, and a uniform moistening ability. In the case of known fillers which consist of strips, it has been found that the strips straighten under influence of encrustation and thereby form a pore foothold for the "biological meadow" and seek to become attached to each other. The purpose of the novel filler is to eliminate this drawback, and for it to be easy to manufacture and install. The novel filler exhibits at least one tensile member (fibre 29), which has been located beside the strips 20. When suspended, this takes up the load such that the strips 20 are essentially unloaded and thereby retain the shape they were given during manufacture. The filler is especially suitable for the biological treatment of sewage and drinking water, i.e. denitrification. <IMAGE>
