With an auxiliary pump connected to Auxiliary Pump 2 in C Mode, C/D Mode, C/D/C Mode, and CFC Mode


with an Automatic Backpressure Valve set to control permeate flow.

The auxiliary pump will run at a defined speed to control the permeation rate, and the Automatic Backpressure Valve will regulate a permeate pressure set-point.
