Examples of membrane filtration process configurations
Membrane filtration batch mode with concentration in tank
•
Simple configuration for viscosities up to
”cream level”
•
The trans membrane pressure is regulated
with the regulation valve
•
The retentate flow is regulated with the
speed of the feed pump in combination
with the regulation valve
•
The concentration factor in the retentate is
calculated from the amount of permeate
collected and the initial feed volume
•
This setup can also be used for diafiltration
applications
Microfiltration mode with permeate flow control pump
•
Unique process control at extremely low
and uniform transmembrane pressure
•
The system pressure is regulated with the
regulation valve
•
A positive displacement pump restricts the
permeate flux and keeps a low
transmembrane pressure
•
Reduces fouling and enables high protein
transmission
•
This approach can be advantageous with
other configurations too
