The dynamic crossflow filtration with rotating discs provides efficient solutions for a variety of applications.
Crossflow methods for separating substances with poor filtration properties are state of the art.
In applications with solvents, abrasive materials etc. the use of ceramic filter membranes is gaining popularity. With the classic crossflow filtration the feed flows over the filter membrane in such a way that no clogging layer can develop on the membranes.
KMPT has further developed the process of Dynamic Crossflow Filtration. In this process rotating ceramic or polymer discs generate a turbulent differential speed of the feed.
This effectively prevents the development of clogging layers which obstruct the filtration. Energy savings of up to 80 % are the key benefits of this new method. The possibility of processing a higher concentration of the retentate to viscosities of 700 mPas opens up new fields of application.
