The present invention relates to hollow fiber membrane modules for use as 'immersion modules' in filtration and/or dialysis methods, in particular whenever impairments due to fouling effects are expected from the use of liquids that are contaminated or lead to deposits. The hollow fiber membrane module comprises at least one housing and a plurality of tubular hollow fiber membranes which are arranged parallel to one another in and/or around the housing in a packing space, wherein the volumetric ratio of all the hollow fiber membranes arranged in the packing space to the packing space is less than 20%. Methods for producing such hollow fiber membrane modules are also provided.

The present invention relates to a device and a method for determining the concentration of organisms in a fluid, where metabolite parameters are recorded by means of a data acquisition unit and subsequently converted.

Device and method for monitoring and controlling biologically active fluids

A device for monitoring a processing liquid comprising at least one sensor for generating at least one monitoring signal, and a device for processing the monitoring signal and for generating a control signal for directly or indirectly influencing the composition or condition of the processing liquid. A device is also provided for detecting, storing, and maintaining the reliability of performance of the sensor. In addition, actuators are provided for converting given criteria or specified values.

The present invention relates to an air humidifier and to a method for humidifying air, the use of special devices enabling air to be humidified with sterile water. A large contact area between water and air is combined with low losses of flow pressure. A membrane contactor having at least one tube membrane embedded in a hydrophilic, porous body comprises the air humidifier. The present invention enables use of coarse filters to ensure that the water is dispersed over a large surface area.
