Permeate line
Introduction
The permeate line carries the permeate that exits the filter through the permeate
outlet.
Permeate flow control
Liquid containing particles or molecules small enough to pass through the filter pores
is collected as permeate.
Permeate exits the filter through the permeate outlet on the filter.
The permeate pressure control valve, placed on the permeate side of the instrument, is
used to shut off the permeate filter outlet and to manually control the permeate pres-
sure.
Recycling
The permeate outlet can be coupled to the tank. This allows permeate to be routed
back to the tank when, for example, the process is set up and calibrated or during CIP.
Permeate recycling is also used when the objective is to run the system at steady state
conditions, this can be applied during TMP scouting, for example.
