The present invention relates to a device for the aeration of liquid media by tube aeration, special tube modules contained therein and the use of a device for the aeration of liquid media.

Modules for membrane aeration

The present invention relates to a method for precipitation of peptide where the mixing step of the peptide with the precipitation aid and the precipitation itself are specially separated.

Device and method for precipitation of peptides

Described is a reactor for irradiating ultraviolet light into a fluid reaction medium (). The reactor consists of at least one housing () which encloses a tubular cavity, with a radiation source () for generating ultraviolet light and an inner tube () which, together with the housing (), forms an irradiation chamber () which, in particular, is of annular shape, the irradiation chamber () being connected at least with an inlet () and an outlet () for the reaction medium () and is perfused by reaction medium () in the longitudinal direction of the tube (), the irradiation chamber () being equipped with means () for generating an additional radial flow routing of the reaction medium ().

Apparatus for irradiating liquids

Apparatus and process for UV irradiation and heat sterilization of fluid media, and in particular of liquids containing microorganisms and/or viruses.

The fluid-bed reactor for biological effluent treatment, using carrier particles for microorganisms, consists of a tank with a retention system for the carrier particles, gas supply units and a jet ejector arranged along the tank for the particle recycle. The propulsion nozzle of the jet ejector is fed with the effluent stream which is to be treated.

Device for solids recycle in longitudinal-flow fluid-bed reactors for

An apparatus for cultivating immobilized micro-organisms consisting of a fluidized bed reactor with fittings for gassing and a retainer system for the immobilized biocatalysts. The fluidized bed reactor is characterized in that the fittings for gassing consist of several segments with gas outlets arranged on the base of the fluidized bed reactor, which admit gas alternately or cyclically. A central gas outflow opening, pointing upwards, can be provided in the fluidized bed reactor as a further gassing unit. The method of operating the fluidized bed is characterized in that circulating gassing occurs in the reactor by means of sequential opening of the gas inflow openings of the segment-shaped fittings. In addition, switches may occur from the central gassing unit to gassing by means of the segment-shaped fittings or vice-versa.

Apparatus for the cultivation of immobilized micro-organisms

The fluidized bed reactor for biological treatment of effluent essentially comprises a container (1) over the base 2 of which elongated gassing units having gas exit apertures (5) are arranged parallel to one another, in such a way that in each case two neighboring circulating currents (8, 9) in mirror-image symmetry are produced in the reactor. In addition, the reactor (1) is supplied with a retention system (16) arranged on the outside for the separation of carrier particles for biocatalysts suspended in the effluent.
