Claim 36:
37. A system for concentrating a liquid feed, the system comprising:
a membrane system configured to receive the liquid feed and produce a concentrate and a permeate, the membrane system including:
a graphene oxide membrane configured to operate at a membrane temperature of at least 60° C.; and
an active cooling system;

a heat exchanger in fluid communication with the membrane system and disposed upstream of the membrane system such that the liquid feed enters the membrane system immediately after exiting the heat exchanger, the heat exchanger configured to cool the liquid feed and heat the concentrate by transferring heat from the liquid feed to the concentrate; and
a controller configured to:
determine a change in a flow rate of the liquid feed; and
adjust a heat transfer rate in the heat exchanger based on the determined change in the flow rate of the liquid feed.
