Gepackte Säule in der aeroben Abwasserreinigung

Aerobic high-performance reactors are occasionally used for the purification of sewage water containing high concentrations of organic pollutants. The increase in performance is achieved by a variety of processes and reactor technologies. One feature which all systems have in common is that shearing forces generate large phase interface surfaces between substrat/oxygen and bacteria/substrat with an intensive mixing at strong turbulences. This improves both the transport of oxygen and the mass transfer. These are also the operating principles of the circulation reactor with a packet column consisting of specially shaped ceramic components. Model studies with synthetic wastewater have shown that this type of reactor is indeed capable of reaching the decomposition performance of familiar high-performance reactors, however, with less energy input and without moving parts
