Solar-powered desalination for agricultural areas


Desalination plants powered by solar thermal are being tested in California in agricultural areas far from the ocean. Water used for crops can be filled with salts, and the problem gets worse over. The Water FX Aqua4 provides clean water from “wastewater, drainage water, runoff, saline groundwater and industrial process water. The remaining brine is concentrated into solid byproducts for resale.” The system is a highly efficient, scalable solar still that produces 30x more clean water than by natural evaporation.
