Description
Summary:Biological reactors using a culture fixed on a fluidized bed are suitable for many applications in waste water treatment. A large number of studies have been carried out at the pilot-plant scale but none exists at the industrial scale for municipal waste water treatment. Examples are: Dorr Oliver (Sutton + Mishra) (1), the Biolex process developed by EBARA (2), and the reactor described by Heijnen (Holland) (3). In the latter two processes, fluidization and aeration are provided by an air-lift system inside the reactor. This article describes the Biolift process whose original feature is that the air-lift system is outside the reactor and is assisted by a system to inject secondary air (process air) into the reactor. This combination allows tight control of fluidization and aeration factors.
