Classification: CPC F  E | IPC E  F

Claim 17:
18. A controller comprising:
memory; and
a processing device coupled to the memory, wherein the processing device is to:
receive first sensor data associated with a first fluid prior to the first fluid entering a first inlet of a pressure exchanger (PX), wherein the PX is configured to receive the first fluid via the first inlet of the PX, receive a second fluid via a second inlet of the PX, and exchange pressure between the first fluid and the second fluid, wherein the first fluid is to exit the PX via a first outlet of the PX, and wherein the second fluid is to exit the PX via a second outlet of the PX;
cause a bearing valve fluidly coupled to a housing of the PX to actuate to provide first fluid to the housing of the PX;
receive second sensor data associated with the second fluid prior to the second fluid entering the second inlet of the PX;
receive user input associated with a target flowrate of the first fluid into the first inlet;
cause a first valve disposed upstream of the first inlet of the PX to actuate based on the user input and the first sensor data to cause a first adjustment of a first flowrate of the first fluid into the first inlet; and
cause a second valve disposed downstream of the first outlet of the PX to actuate based on the first sensor data and the second sensor data to cause a second adjustment of a second flowrate of the second fluid into the second inlet.
