The new developed BMF-120 cross-flow technology, overcomes all earlier barriers to successful commercial implementation of membrane filtration as alternative to kieselguhr filtration in breweries. The key to the feasibility of this new technology is a newly developed cleaning strategy and the excellent properties of the applied NORIT membranes.

Product description
One filter skid has a maximum capacity of 120 hl/h. Because of the modulary set up a filter line can be composed of maximal 6 skid
(with a combined capacity of 720 hl/h).

Principle of Operation
The filter is fed by the feed pump, which provides the necessary pressure. The filter itself is contained in a recirculation loop, with a second pump, providing the necessary Cross-Flow velocity through the membrane fibres, in order to keep the deposition of solids on the surface as low as possible.

The recirculation loop has a bleed valve fitted, in order to control the concentration of solids in the recirculation loop. The filter itself is formed by porous fibres, with a very well defined pore size. The mature beer is pumped through the fiber, while part of the beer permeates through the wall, driven by the pressure difference between the inside and outside of the fibres, separating the beer from all haze causing constituents.
