Filtration is one of the key processes in brewery operations. In addition to a bright, shiny filtrate with optimum turbidity, technological requirements also include an improvement in the physical stability of the beer. The filtration achieves high microbiological safety for the filled product.
On top of this, there are also economical requirements: Users want a long filter service life, low operating costs and systems that are easy to operate. These requirements are crucial to the new cross-flow filtration concept.
At a glance
Controlled transmembrane pressure depending on the position of the module in the filter unit
Flow reversal at the membrane modules using a double infeed
Targeted backflushing of individual membrane modules during filtration and cleaning
Thanks to the series connection of the membrane modules, the cross-flow process requires a lower pump output and smaller nominal pipe diameters when compared to a parallel connection.
Controllable filtration concepts
It is possible to individually regulate the transmembrane pressure for different filterability of different beers. The sedimentation tank also guarantees optimal service life with a high number of yeast cells.
Hygienic plant operation
The ability to provide targeted, intensive flushing during cleaning and to provide 85 °C sanitisation allow a high standard of hygiene to be achieved.
Specific membrane development
Optimum filtration results are ensured through our close cooperation and continual further development together with our membrane manufacturer.
