Die Form des Substratmaterials kann nahezu beliebig gewählt werden, bekannt sind Tropfkörper, Scheibentauchkörper und Vliesbettanordnungen. In der Regel wird das Substrat material während der Wasseraufbereitung innerhalb des Bioreaktors bewegt; die parallel zueinander angeordneten Scheiben eines Scheibentauchkörpers werden bei spielsweise gedreht, wobei die Oberfläche des Substrats zeitweilig auch an die Luft gelangt. Das Substrat dient der Aufnahme der vor allem aus Bakterien bestehen den biologisch aktiven Schicht. Neben der Auswahl der biologisch aktiven Schicht ist hierbei auch die Auswahl des Substratmaterials von großer Bedeutung für die Funktion des Bioreaktors. Geeignete Substratmaterialien haben eine hohe Abrieb festigkeit und sind chemisch resistent. Sie müssen den Bakterien der biologischen Beschichtung außerdem ausreichende Schutzzonen bieten, um das Ablösen von Bio masse zu erschweren. Die Oberfläche des Substratmaterials muß so beschaffen sein, daß sich die gewünschte Menge an Biomasse darauf anlagert. Wichtig ist, daß sich auf den bzw. zwischen den Substraten kein Schlamm anreichert, was zu Verstop fungsproblemen führt.Bioreactors are used in wastewater technology to treat wastewater set. Here you make the properties of biologically active material, e.g. B. a layer of bacteria, the biological contaminants to use len metabolism and thus quasi filter out. Known bioreactors consist essentially of a vessel for receiving or carrying Waste water and a substrate material immersed in this vessel. The shape of the Almost any substrate material can be chosen, trickling filters are known, Disc diving bodies and fleece bed arrangements. Usually the substrate material moved within the bioreactor during water treatment; the Discs of a disc diving body arranged parallel to one another are used for for example rotated, the surface of the substrate temporarily also in the air reached. The substrate is used for the absorption of bacteria the biologically active layer. In addition to the selection of the biologically active layer the selection of the substrate material is of great importance for the Function of the bioreactor. Suitable substrate materials have high abrasion strength and are chemically resistant. You need the biological bacteria Coating also provide sufficient protection zones to keep the organic from peeling off to complicate mass. The surface of the substrate material must be such that that the desired amount of biomass is deposited on it. It is important that no sludge accumulates on or between the substrates, which leads to blockage problems.

Die Poren des Polyurethanschaumstoffs sind für biologisch aktive Beschichtungen und Sauerstoff gut erreichbar. Die aktive Oberfläche beträgt bis zu 5000 m²/m³. Weitere bekannte Kunststoffmaterialien zur Verwendung als Substratmaterialien sind Polyäthylen und Polystyrol. Diese Substrate sind jedoch sämtlich teuer, da sie speziell für Bioreaktoren in geringen Mengen hergestellt wer den.Suitable known carrier materials consist for example of polyurethane or Polyurethane foam. The pores of the polyurethane foam are for biological active coatings and oxygen easily accessible. The active surface is up to 5000 m² / m³. Other known plastic materials for use as Substrate materials are polyethylene and polystyrene.

In einem bevorzugten Ausführungsbeispiel werden als Fasermaterial verrottungsfe ste Synthesefasern aus Polyamid oder Polyester eingesetzt. Um hohe Porösität und ein hohes inneres Volumen zu erzielen, werden Grobfasern im Titerbereich zwischen 8 und 300 dtex verwendet. Dadurch wird ein Luftanteil im Inneren des Reini gungskörpers von 65 bis 99 Vol.-% erzielt. Dieses hohe innere Volumen und die Gewebestruktur ermöglichen eine gute Haftfähigkeit für das biologisch aktive Ma terial und auch eine leichte Abgabe der Stoffwechselprodukte an durchlaufendes Wasser.In a preferred embodiment, rot-proof as the fiber material Most synthetic fibers made of polyamide or polyester are used. To high porosity and To achieve a high internal volume, coarse fibers in the titer range between 8 and 300 dtex used. This creates an air content inside the Reini achieved body of 65 to 99 vol .-% achieved. This high inner volume and the Fabric structure allow good adherence for the biologically active material material and also an easy delivery of the metabolic products to continuous Water.
Als Binder können alle bekannten wasserfesten, elastischen Polymere, bevorzugt Synthesekautschuk- oder Acrylatdispersionen, verwendet werden. Der Binder ist nach allen bekannten Methoden einzuimprägnieren, z. B. zwischen zwei Walzen. Man kann ihn auch durch beidseitiges Besprühen auf das Vlies aufbringen.All known waterproof, elastic polymers can be preferred as binders Synthetic rubber or acrylate dispersions can be used. The binder is impregnated by all known methods, e.g. B. between two rollers. Man can also apply it to the fleece by spraying on both sides.
Das Verhältnis von Fasern zu Binder kann variiert werden zwischen 90 : 10 und 20 : 80. Die Fertiggewichte des erfindungsgemäßen Substratmaterials liegen 100 und 2000 g/m².The ratio of fibers to binder can be varied between 90:10 and 20:80. The finished weights of the substrate material according to the invention are 100 and 2000 g / m².
