A device () and method for media filtration with a preparation container (). A chamber () containing a dissolvable medium () is situated between the container inflow and outflow, and has a filter (). A mixing arm (), connected to the inflow, protrudes into the medium in the chamber with at least one mixing nozzle (), disposed at the free end () of the mixing arm for generating a directed jet of solvent. The preparation container has bottom () and top () parts bracketing the chamber. The filter is a sterile, has on the filtrate side facing the outflow, a circumferential outer edge () resting on a circumferential rest edge () of the bottom part of the preparation container and is connected fixedly thereto. A sterilised filtrate space () is formed between the filtrate side () of the filter and the outflow situated in the bottom part.

Membrane with performance enhancing multi-level macroscopic cavities

A container has an outflow arranged in the vicinity of the bottom and a vortex breaker mounted upstream from the outflow for preventing foaming. The vortex breaker has a vertical main wall and two vertical side wings oriented away from one another to define a T-shape. The main wall merges into a fixing arm. A method also is provided for producing the vortex breaker. The method includes a) cutting a flat plate to define a main wall, two side wings, and a fixing arm connected to the main wall; and b) folding out the side wings in opposing directions in each case into a final position arranged transverse to the main wall. The vortex breaker is applicable in chemistry, biotechnology, and filtration technology.

The invention relates to a filter module and an apparatus for the static filtration of liquids using filter cells having deep bed filter layers and using spacer layers. According to the invention the filter module has a stack of n filter cells and n+1 spacer layers for filtrate and at least one channel arranged in the interior of the filter module. In this case n is &#x2267;1. The filter cells consist of a draining spacer layer for feed liquid and deep bed filter layers which are arranged in a sandwichlike manner thereto and which are joined to one another at their circumference toward the at least one channel at the rim via a sealing compound and wherein the spacer layers for filtrate are furnished with the sealing compound at the rim on their external circumference. The invention can be used to remove substances from liquids, in particular for clarification and sterile filtration in the sectors of the foods industry, drinks industry, pharmaceuticals and chemicals industry, and also in the field of environmental engineering.
