Textile material used in biological waste water treatment plant includes effect structures and base structure which is independent of load bearing capability

摘要

Along the textile (1), in addition to the effect structures (2) a supportive base structure is provided, which is independent of the load bearing capability. An Independent claim is included for the method of manufacture. Preferred Features: The effect structures are welded, adhered, sewn, knitted, woven or flocked with the supportive base structure of warp threads (3). The effect structures lie in the weft direction and comprise effect material introduced in that direction. The basic supportive structure has wefts and effect structures are provided in addition. Effect structures include effect structure strips forming passages (5) transverse to or at an angle to the length of the material. They form in addition crossing points angled with respect to the length, with standing threads lying in the region of crossing points of the effect structure strips. Further variants based on the foregoing principles, and a waste water cleaning module employing the textile are detailed. Salient features include surface modification of the cloth, tubular carrier sections for it and thermal forming. The textile forms a substrate to be hung or inserted into a wastewater treatment tank, with the addition of braced, supportive framing and resilient attachments. Floats, baffles and basal aeration units are included. There is at least one sensor on the frame. Gas introduced, rises up over the textile surfaces, promoting biofilm formation.
