The Thermal Desalinator is a machine which converts Seawater and either Steam Hi, Steam Lo, or Steam Depleted into Water and Brine. Due to the high fuel cost for making steam, Groundwater Pump is vastly more efficient if there is sufficient rainfall to replenish groundwater aquifers.
The Brine byproduct can be utilized in Electrolyzers to create Chlorine to treat Waste Water or in fed into Wastewater Treatment machines to convert Toxic Slurry into Slag. The Evaporation Pond and Evaporation Pond (Heated) can also process Brine into Salt. However due to the high fuel cost for making steam, the production of Salt from Seawater with the Evaporation Pond is several times more energy efficient.
