Claim 38:
39. 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:
an active cooling system, a passive cooling system, or a combination thereof; and
a graphene oxide membrane configured to operate at a membrane temperature of at least 60° C.;

a first heat exchanger in fluid communication with the membrane system and disposed upstream of the membrane system;
a second heat exchanger in fluid communication with both the first heat exchanger and the membrane system and disposed between the first heat exchanger and the membrane system, such that the liquid feed enters the first heat exchanger, the second heat exchanger, and the membrane system sequentially; and
a controller configured to:
determine a change in a flow rate of the liquid feed; and
adjust a heat transfer rate in the first heat exchanger or the second heat exchanger based on the determined change in the flow rate of the liquid feed;

wherein:
the first heat exchanger is configured to cool the liquid feed and heat the concentrate by transferring heat from the liquid feed to the concentrate; and
the second heat exchanger is configured to cool the liquid feed and heat the permeate by transferring heat from the liquid feed to the permeate.
