6. A process for producing water and salt comprising:
feeding saltwater to a solar still unit where the saltwater is exposed to solar radiation to produce humid air and brine, wherein the solar still includes a flow management structure including multiple layers which direct flow of saltwater from a saltwater inlet along the multiple layers to a brine outlet;
feeding the brine to a brine storage container where it is dried to produce salt;
directing the humid air from the solar still to an atmospheric water generator to produce freshwater from the humid air; and
directing the freshwater from the atmospheric water generator to a plasma treatment chamber which performs plasma treatment on the freshwater to produce plasma activated water.
