Claim Text:
1. A water recovery system, comprising: a generally sealed enclosure; a first air treatment unit within the enclosure, said first air treatment unit configured to draw water vapor from a liquid desiccant and to transfer the water vapor to an air stream flowing through the first air treatment unit, said first air treatment unit including a plurality of structures arranged in a substantially vertical orientation, said structures being spaced apart from each other with an air stream gap between each pair of adjacent structures, each structure having at least one surface facing an air stream gap across which the liquid desiccant can flow, wherein the air stream flows through the air stream gaps between the structures such that the liquid desiccant humidifies the air stream, each structure further includes a separate desiccant collector at a lower end of the at least one surface for collecting liquid desiccant that has flowed across the at least one surface of the structure, said desiccant collectors of the structures being spaced apart from each other to permit airflow between the collectors, said first air treatment unit further including a liquid desiccant source for supplying the liquid desiccant to the structures; and a second air treatment unit within the enclosure receiving the air stream treated by the first air treatment unit, said second air treatment unit causing condensation of the water vapor in the air stream without use of a desiccant to produce drinkable liquid water that can be transported outside the enclosure, wherein the air stream treated by the second air treatment unit is received by the first air treatment unit; and an air mover for circulating air between the first and second air treatment units.
