Abstract:
1. A method of desalinating water, comprising: transferring heat from a coolant to a feed water to increase a temperature of the feed water and decrease a temperature of the coolant; further increasing the temperature of the feed water; further decreasing the temperature of the coolant using an evaporative cooler comprising at least one tube through which the coolant flows, wherein the evaporative cooler sprays salt water on an outer surface of the at least one tube, and the evaporative cooler forces dry, unsaturated air to flow over the salt water on the outer surface of the at least one tube such that a portion of the salt water evaporates and lowers the temperature of the coolant inside the at least one tube; and producing desalinated water from the feed water by inputting the feed water and the coolant into respective portions of a membrane desalination unit.
