Modellierung des Konzentrationsprofils in einem Rotating Disk Contactor

Modified Rotating Biological Contactor

The disposal of domestic wastewater without any treatment into the drainage systems is considered a source of pollution threatening the population. Industrial waste water discharge to the environment is one of the environmental problems which must be controlled. Current mainstream technologies for treatment of domestic wastewater such as activated sludge and tertiary nutrient removal are too co...

Denitrification in a closed rotating biological contactor: effect of disk submergence

Several studies have employed rotating biological contactors (RBCs) for nitrogen removal. However, partially submersed disks are used for nitrification, while completely submersed disks are used for denitrification. The objective of this study was to investigate the effect of disk submergence in the performance of rotating biological contactors, in terms of the denitrification process. Two RBCs...

Erweiterung des Common Information Model zur Modellierung von dezentralen Energieprodukten an einem regionalen Marktplatz

Durch den aktuellen Wandel der Energiewirtschaft von einer zentralen hin zu einer dezentralen Energieversorgung ergeben sich technische und konzeptuelle Herausforderungen, vor allem auch für die bisher verwendeten Standards und Normen. Prozesse der Geschäftsebene werden dabei vorrangig mit dem Common Information Model modelliert, welches momentan auf eine zentralisierte Stromversorgung und den ...

Automatische Modellierung gebundener Handschrift in einem HMM-basierten Erkennungssystem

Model for oxygen transfer in rotating biological contactor.

Rotating biological contactor is being widely used for wastewater treatment but there is an apparent lack of knowledge about the rate at which oxygen transfer occurs, in physical and biological system. In this study the transfer of oxygen from air to water by a rotating disc air-liquid contactor in physical system is investigated. The oxygen transfer model suggested by Kim and Molof, Water Sci....
