working principle cross-flow filtration (diafiltration mode)

 

A feed solution or suspension is pumped under pressure over a membrane. This membrane is selectively retaining the desired components. The product can be the permeate or retentate. Possible operations are concentration and diafiltration.
Membrane processes often offer the more efficient process alternative for separations: combined cleaning, desalting and concentration of suspensions or solutions, separation of solvents, desalination, gas separation or solvent recovery. Here you find calculation tools for membrane processes: calculations membrane processes

The operation pressure typically ranges from 1bar for microfiltration to 40bar and in some cases above for reverse osmosis
