摘要:
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.

摘要:
A device and a process are described for membrane electrophoresis or electrofiltration. The device contains at least one input chamber, one output chamber, and one cathode chamber and anode chamber each, whereby the individual chambers are separated from one another by membranes, and are integrated into a permanently attached module with membranes, and whereby the electrodes are integrated into the module, and the module is connected to constructions enabling continuous flow through the input and output chambers, as well as through the electrode chambers. It is emphasized that this abstract is provided to comply with the rules requiring an abstract which will allow a searcher or other reader quickly to ascertain the subject matter of the technical disclosure. It is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the appended issued claims. 37 CFR §1.72(b).
摘要:
A filter cartridge unit including a first end plate, at least one second end plate, and a filter cartridge that is arranged between the end plates. The filter cartridge is connected, in a form-fitting and fluid-tight manner, to its adjacent end plates in a circumferential subarea of contact surfaces thereof using an adhesive.

摘要:
An adapter is provided for fastening a filter element in a cylindrical receiving opening of a bottom part of a lower piece of a filter housing. The adapter has at least one seal arranged in a peripheral groove on the circumference of the adapter to permit fluid-tight separation of a non-filtrate chamber, which surrounds the external jacket of the filter and from which medium to be filtered can be delivered to the filter, from a filtrate chamber into which the filtrate can be introduced from the filter. The seal is connected by injection molding to a base surface of the peripheral groove and is at a distance from at least one side wall delimiting the base surface of the groove.

摘要:
A method for testing the integrity of filter elements, in which the convective component of the volumetric gas flow rate is determined from the ratio of the volumetric gas flow rates and the ratio of the solubility or diffusion coefficients of two different gases in the wetting liquid of the filter elements or is determined from the ratio of the volumetric gas flow rates and the ratio of the solubility or diffusion coefficients of a test gas in two different wetting liquids.
