Anaerobe und anoxische Behandlung von Abwaessern in einem neuen Rotationsscheibenreaktor

A new rotation disc reactor for anaerobic and anoxic treatment of wastewater is presented. The discs are covered with a structured textile material for immobilization of bacteria. In contrast to the wellknown rotating disc contactor the discs are completely flooded. A slow rotation causes a flow into the gaps which are formed by the parallel discs and increases the mass transfer rate. For the anaerobic treatment of a wastewater produced by the dewatering of sewage sludge and for the denitrification of a synthetic wastewater high removal rates could be obtained resulting from a high concentration of immobilized bacteria
