Abstract
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 ≧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.
