Separating elements kept apart and which are arranged vertically in the tower or in the bed. The second way which can be described as "random media" is made up of relatively small ones Elements or bodies composed which are randomly distributed in the tower or in the bedi the invention refers to the last mentioned type of filling media »

In the description and in AEEN claims under the designation is "randomly distributed packing" (random packing element) to mean an element or a fill = body whose size and shape is chosen so that a large number of these bodies in a Surm or bed can be arranged to a filling, the. Elements or bodies are not arranged in a specific orientation to one another ο

In the construction of packing elements that are randomly distributed in a biological filter, it happens on bringing two contradicting demands into decline «On the one hand, it must be biological the active surface of the filling should be as large as possible in order to achieve the greatest possible efficiency, while, on the other hand, the cavities must be large enough to avoid stagnation (ponding) ο apart from these two contradicting requirements do the elements have to be shaped like this? that they can be manufactured economically, both in terms of the material costs as well as the manufacturing costs for a large number of elements "

3 0 9881/0783

Me invention has therefore provided _for in the first place the task of creating filler, the shape of these two contradictory! Gentigt demands and their production costs are low "

The invention thus relates to filling bodies sur random distribution in a biological filter _{tower or filter bed P} characterized by a boundary wall with at least white openings and several inner walls which are arranged within the outer boundary wall and thus form a unit and which have a surface on which a biological one Activity occurs j, with at least one passage between the two openings in the body, which allows a connection between the openings and wherein the total surface of the inner walls is larger than the surface of the boundary wall »

Such a filler body can expediently have the shape of a cylinder open at both ends with at least four diametrical ribs _P which extend over the entire length of the cylinder. The cylinder can be unperforated or perforated _p and the diametrical ribs can contain further ribs, which are arranged at a right or at an acute angle on the diametrical ribs. The length of the cylinder is expediently not greater than its diameter _{or the like}

The invention is described below with reference to the drawing, in which some embodiments of Packings according to the invention are shown as non-limiting examples. Show it:

309881/0783

In Figures 1 and 2, theoretically the simplest shaped filler body according to the Brf-iudung is shown} the filler body has a boundary wall 1 in the form of a cylinder, which is open at both ends, and four diametrical ribs 2 within the boundary wall 1 » which extend over the entire Xsäuge of the cylinder. In this version, neither the boundary wall 1 nor the lip « 2 are perforated.

If the barch knife of the body is assumed to be 1 and its length also assumed to be 1, the material thickness being as small as possible, then the free surface of the boundary wall 1 (inside and outside) is approximately 6.4 surface units. The total surface of the lips is about 8 units of area. The entire surface of the ribs 12 is therefore larger than the entire surface of the boundary wall 1. This is not the case if only three diametrical ribs are arranged within the boundary wall, "You. Total surface of 3 ribs is about 6 areas in this case" , ie less than the entire surface ~ Her boundary wall.

The embodiment shown in Figure 3 has a cylindrical boundary wall 3 which is open at both ends, as well as 5 diametrical ribs 4 and short ribs 5 arranged radially between the diametrical ribs 4 »

In the embodiment of Figure 4, there is one limitation -wall 6 provided similarly to the previous embodiments. They cross ribs 7 and are arranged in a chord shape with respect to the circular cross section of the boundary wall 6.

309881/0783

In the outer shape of FIG. 5, the boundary wall is 9 are again cylindrical, and they are curved Ribs 10 are provided which look the entire length the boundary wall 9 extend »Bai the protruding specified embodiments, neither the boundary wall nor the ribs are perforated or perforated, and the total surface area of the ribs or inner walls is greater than the total surface area of the boundary wall.

In the embodiment according to FIGS. 6 and 7, a cylindrical delimitation wall 11, open at both ends, is provided in which the openings 12 are arranged o Inside the delimitation wall 11 there are four diametrical _{ribs 13 S} , adjacent ribs being connected by a curved rib 14 ; the curved ribs form an inner cylinder «The inner cylinder can contain the holes 15»

In the embodiment according to Figures / and 9, a cylindrical outer wall 16, open at both ends, and four diametrical ribs 17 are provided. Furthermore, four ribs 18 are provided in the longitudinal direction , each of these ribs being perpendicular to the diametrical rib associated therewith. As in the previous embodiment, the boundary wall 16 is provided with openings 19.

In the embodiment according to FIGS. 10 and 11, a cylindrical delimitation wall 20 which is open at both ends and which is provided with openings 21 is provided. Furthermore, four diametrical ribs 22 are provided, each of which carries two smaller ribs 23 or 24 arranged vertically.

309881/0783

In the embodiment shown in FIGS. 12 and 13, a cylindrical delimitation wall 24 with openings 26, which is open on both bands, is again provided. Furthermore, four diametrical ribs 27 are provided, each of which has a few small ₉ ribs 28 at right angles.

In the embodiment NaOH Figures 14 "to 17 the zylin & rissh © boundary wall 29 contains openings 30 ο The diametrical hip 31 extend SiOH from the wall 29 to a short hollow cylinder 32" in the middle of each diametrically © Hipp® carries a H @ ih © of small ribs 33 arranged at right angles.
