Abstract:
1. A water distillation system, comprising: a membrane distillation unit which produces desalinated water from feed water comprising salt water; a primary water heater which raises a temperature of the feed water upstream of the feed water entering the membrane distillation unit; and an evaporative cooler which lowers a temperature of a coolant upstream of the coolant entering the membrane distillation unit, wherein the evaporative cooler comprises at least one tube through which the coolant flows, 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.
