    Filters for aquariums, fish ponds, swimming pools, swimming ponds or the like
    The invention relates to a filter for aquaria, fish ponds, swimming pools, swimming ponds or the like. according to the preamble of claim 1. 5
    Such filter devices, in spite of their name, not only fulfill a filter function, but also accomplish the removal of filtered-out biological material by colonizing microorganisms; in many cases, the term biofilter is used for such filters. In order for these devices to be reliable and perform well under the ever-changing operating conditions, it is necessary to provide a flow distributed as evenly as possible through the volume, as in the formation of preferred flow paths, the water to be filtered along these paths rapidly and without sufficient filtering through the device flows, while in other areas to form dead areas in which lack of flow 15 no filter effect is deployed. It is also important to ensure that blockages are prevented and that, if they occur locally, the overall performance of the filter does not or only slightly less suffers. Finally, the solid surface provided by the filter, hereinafter referred to as a debris blanket, must be so large that the microorganisms that perform the biodegradation can develop in sufficient quantity thereon.
    For filters in pipes, tanks and filter basins, most of the material removal takes place mainly on the dirt blanket. Thus, the essential criterion of a good filter is its largest and uniformly streamed dirt cover, as is the case for example with a 25-fold filter
    In addition, the filter should be cost-effective and mechanically stable and chemically safe under all storage or transport conditions and have sufficient life during operation.
    In conventional biofilms and planted soil filters, the dreaded "clogging effect" (chemical, biological colmation) can occur when overloading, which is the formation of a fully dense biofilm (reduction of the pore volume), which 30 • «· · ·· ····· «· · · · · · ···································. ··· * ··· ·· * ί ϊ " ·· * '· »' * ·· * ··· * ·· ·· This effect can be eliminated in the previous filter devices only by a removal of the uppermost filter substrate layer.
    From the above it is apparent that the previously much used foam rubber materials udgl. 5 meet these conditions very incomplete, and that also various other structures in which differently shaped rings or tubes or plates are used as filling material, or filters, as known from EP 852 222 Al, in which glass wool stuffed into a cylinder and flows through from top to bottom of the water to be purified, these conditions only partially with expert care and even then 10 under all reliable fill.
    It has proven variously glass wool or rock wool in another form than filter material, as is apparent in particular from WO 96/38387 Al: This glass fiber mats, as offered for insulation in building construction for sale, rolled up 15 and in the vertical axis in put a big tank. The gussets between the mats are sealed and dirty water flows vertically from below, thus in the direction of the winding axes, through the rollers. However, the water preferably flows in the ever larger gaps between the individual layers than through the layers themselves, and also the peripheral areas to the sealed gussets become more permeable and permeable during operation, so that over the course of the operation, preferred flow paths result, which as mentioned above, significantly reduce the filter performance. In comparison with the glass wool simply stuffed into a container according to EP 852 222 A1, it is favorable that the adverse effects of local blockages by offering numerous alternative routes are not so unpleasant. 25
    DE 20 2009 003 919 Ul discloses a filter material having a plurality of granules and gravel layers, which are arranged one above the other and the associated filter device is flowed through by a supply line from bottom to top, wherein the filter device is not universally applicable by the specific layer structure, but only for larger 3 0 plants such as fish ponds or bathing lakes.
    It is an object of the invention to provide a filter having the aforementioned desirable properties and avoids the disadvantages of prior art filter
    According to the invention, this is done in accordance with the characterizing features of claim 1. In other words, that lumpy pieces of plastic fiber, glass wool, rock wool, zeolites, Schaumstofflocken or the like., In the following generally called filter substrate, on mats Wirrgelege, in particular of geosynthetics consisting, applied and 5 is wound in one embodiment via a tube with perforated lateral surface in at least three layers, the mechanical positioning of very fine filter substrate in flake, Körner-, or spherical shape is favorable Thus, the entire filter volume for colonization by microorganisms Available, each filter flake, each Filterkom or each filter ball has its own dirt blanket. 10
    In the present invention, the "clogging EfFekt" is completely prevented by the spatial arrangement of the filter substrate in a coarse mesh matrix.
    Such a filter apparatus, due to the three-dimensional structure of the knit fabric and mineral wool located in the cavities and depressions of the knitted fabric, constitutes a filter which combines a maximum of solid surface area per unit area with a maximum of mechanical stability. It is therefore, if at all only in small local areas, to form preferred flow paths, the occlusions may have only very small-scale effects. Due to the fact that the individual 20 winding layers come to rest on top of each other in comparison to the randomly filamented mineral wool layers, there is a substantially spiral movement of the water to be cleaned from the outermost surface of the roll (acting as a dirt cover) to the central drainage pipe. This extension of the water path in the filter along a particularly large specific surface area leads to excellent filter properties.
    In particular, the products called "soaky layer" of synthetic raw materials, the geotextile raw materials and the like, come as material for the entanglement. into consideration. The transition between scrim, nonwoven, non-woven texile, woven or stretched geogrid 30, or mesh is fluid, such products are described, for example, by Naue GmbH & Co. KG in Espelkamp, Federal Republic of Germany; from Tengate Geosynthetic Austria GmbH in Linz, Austria; by Tenax Kunststoffe GmbH in Lindau, Federal Republic of Germany; offered by Ketinger Vliesvertrieb GmbH in Freudenberg, Germany, and many others. In the knowledge of the invention and the easily collected detail data of
    In the field of filter technology, the specialist in the field of filter technology can easily select the materials to be preferred for each individual product. As mineral wool, the mineral wool commonly used in building construction can be used. Further features and advantages of the invention emerge from the subclaims and the following description of the preferred embodiments, which refer to the accompanying figures, wherein identical or similar components are identified by the same reference numerals. The invention is explained in more detail below with reference to several exemplary embodiments and with reference to the figures. 1 shows a spatial representation of a filter according to the invention, FIG. 2 shows a spatial representation of the filter in a semi-rolled form, FIG. 3 shows a spatial representation of the filter in a rolled-up form, FIG. 4 shows a plan view of the filter 5 shows a sectional view of the filter of FIG. 4, FIG. 6 shows two serial embodiments of filters, FIG. 7 shows a parallel embodiment of filters, and FIG. 8 shows three possible arrangements of the filter. 20
    Fig. 1 shows a erfmdungsgemäßes filter 1 with a tangle 2 or its spatial structure with cavities, projections and recesses 5, which are filled at least to a good part with filter substrate 3 and with a Hüllgewebe 4, preferably a thin mineral wool layer, are surrounded , 25
    Fig. 2 shows a three-dimensional view of the filter 1 in halbzusammenrollollter form and Fig. 3 in a fully rolled up to a winding form, to aid in winding or later easier assembly in the aquarium, fish pond, swimming pool, etc. the filter 1 can be wound over a pipe (not shown).
    FIG. 4 shows a plan view of the filter 1, the individual flakes, particles, etc. of the filter substrate 3 and a wrapping fabric 4 being visible. 30 ·· ·· * · · ♦ -5-
    Fig. 5 shows a purely schematic view of the section taken along the line V-V of Figure 4, wherein the filaments forming the Vorrgelege 2 serpentine; since this is the case in the other cutting planes as well, the cavities and depressions 5 are thereby formed. The individual structures of the filter substrate 3, which fill the cavities and depressions 5, are clearly visible. The wrapping fabric 4 follows the surface in the individual wells 5 and elevations, z.T. into the cavities, which makes it a kind of durable packaging material. Furthermore, the covering fabric 4, which usually consists of mineral wool, serves for easier replacement of the individual filter substrates 3 or optionally also filters 1. 10 FIG. 6 shows two embodiments with serial arrangements of a plurality of filters 1, which in the first embodiment Al are connected to a net or the like , wrapped and bottlenecks, called node 5, are interconnected, while in the second embodiment A2, the individual filters 1 are connected by a cable 6 or rolled up around the cable 6. In this case, the cable 6 serves as well as an easier interchangeability of the individual filters 1, as in FIG. 5, the wrapping fabric 4th
    Fig. 7 shows an embodiment with a parallel arrangement of the filter 1, which are wound around parallel tubes 7 with perforated shell. These tubes 7 are connected at one end to a supply pipe 8, which serves as input I for the water to be purified, and at the other end to a discharge pipe 9, which serves as the outlet O for the purified water. By this arrangement, the filters 1 are supplied with water around the individual tubes 7, which have Durchflußöffimngen for the water.
    Fig. 8 shows three possible arrangements of the filter 1, wherein in the first arrangement Bl 25, the filter 1 are arranged standing in a basin 10; in the second arrangement B2, the filters 1 are arranged lying and in the third arrangement B3, the filters 1 are poured over one another at will.
    Due to the mechanical positioning of a very fine filter substrate 3 in a spatial matrix of cavities and depressions 5 compared with the prior art, the filter 1 according to the invention is suitable for any desired flow rate. In this case, the filter substrate 3 is fixed by superimposing or rolling the individual random pulley 2 so that no discharge takes place even at high flow rates. »· * ♦ P · t · · ** * ♦ * k · ·· * ♦ · ··· -6-
    As can be seen from the explanations and figures, it is possible to lay a wound around a flexible drainage pipe filter 1 in a zig-zag or spiral shape at the bottom of a swimming pond or aquarium. It is possible to arrange a plurality of identical or similar filters in the form of parallel tubes 7 or in series (in terms of flow), and it is also possible to arrange corresponding filters 1 in their own receiving waters of the water bodies to be cleaned.
    An advantage of the invention is that the filter 1 can be traversed by an anoxic, anaerobic, or an aerobic-anaerobic (mixed form) or only an aerobic medium as required. Anoxic describes a state in which the dissolved oxygen concentration is so low that certain groups of microorganisms assume oxidized forms. In contrast, if there is no undissolved oxygen, it is an anaerobic environment, whereas dissolved oxygen is an aerobic system. The respective load from the water flowing through leads locally to a suitable environment.
    In a preferred embodiment, the material Hüllgewebes 1 is fibrous (non-woven fabric) and consists for example of rock wool with a fiber diameter of 0.002 - 0.006 mm, but also any other water-resistant material can be used. The density of the rock wool in the state of use as a sheath is 0.1 - 0.2 kg / cm3.
    The protrusions, cavities and depressions 5 produced by the snake-shaped course of the interference layer have a characteristic of 1 to 50 mm in the usual applications (aquariums, fish ponds, 25 swimming pools, swimming ponds or the like), usually 20 mm on average.
    A further advantage of the filter 1 according to the invention is that it is more flexible than a sand filter and achieves a higher filter performance, wherein the rolled-up filter (coil), also in 30 flow-through pipes or open, in non-coiled form, floating, for example in a basin as a floating filter, can be arranged.
    The invention is not limited to the illustrated and described embodiments, but can be variously modified, especially when using transparent tubes, the incoming Aigenwuchs with the filter substrate 3 can improve the filtering effect even more. By exchanging or rinsing such a tube, the organic substance can also be removed.
    The invention thus relates in essence to a filter 1 for aquaria, fish ponds, swimming pools, swimming ponds or the like, and is characterized in that the filter 1 is a circlet 2 having cavities and projections and depressions 5 on the surface, the crosstie 2 consists in particular of geosynthetics and in that in the cavities and depressions 5 filter substrates 3, preferably made of plastic fiber, and / or glass wool and / or rock wool, and / or zeolites, and / or foam flocks are incorporated.
    Preferably, the filter substrates 3 are formed lumpy or flaky or granular, with granular does not say anything about the hardness, but an opposite to "flaky" indicates.
