The present invention relates to an apparatus for an extracorporeal blood treatment having an extracorporeal blood circuit in which a dialyzer is arranged and having a dialyzate circuit, wherein the blood circuit is in fluid communication with a first chamber and the dialyzate circuit is in fluid communication with a second chamber of the dialyzer, and wherein the two chambers are separated from one another by a semipermeable membrane, with a dialyzate pump for a conveying of the dialysis solution being present in the dialyzate circuit, wherein the apparatus has a control unit that is configured to operate the apparatus in a first phase and in a second phase following the first phase, wherein the dialyzate pump is operated with a smaller flow rate in the first phase than in the second phase and/or wherein the dialyzate pump conveys a dialysis solution in the first phase that is of a higher concentration with respect to at least one component than in the second phase.

Apparatus for an extracorporeal blood treatment

A dialysis machine is provided that includes an apparatus for treating fluids, in particular, for treating water for dialysis. The apparatus includes one or more hollow fiber membrane filters, a plurality of fluid lines, one or more sampling points, and one or more valve connections. The apparatus is configured such that contaminants can concentrate in a first hollow fiber membrane filter and conclusions can be drawn as to the contamination of the water. An analysis value can be determined from samples of concentrated contaminants. A method for monitoring the apparatus for contamination, is also provided.

Dialysis machine containing a device for the treatment of liquids, in particular water, and method for monitoring the device for contamination

The invention relates to a method for the processing of protein-containing suspensions or solutions, for example for concentrating or purifying the protein-containing particles or dissolved protein-containing substance contained in the suspensions or solutions, wherein the protein-containing suspensions or solutions are filtered by means of a filter module and the protein-containing particles or dissolved protein-containing substance retained in the filter module are conveyed out of the filter module by means of a backwashing fluid.
