Der Bio‐Hochreaktor — eine biologische Abwasserreinigungsanlage in Hochbauweise

The Bio-tower reactor – a tower-type biological waste water purification plant. A novel biological wastewater purification plant is presented which has been developed from the viewpoint of space-saving and which in comparsion to conventional plant shows more structural similarities with tank assemblies. The developments leading to the construction of the bio-tower reactor are first described and the fundamental concepts of the constructional engineering and gassing technique involved are outlined. The construction and operational behaviour of the plant are dealt with and the results regarding sludge separation, gassing technique, and space loading are discussed.
