Treatment Plants in Solar Thermal Power Plants
"The concentrated solar power plants that have chosen TEDAGUA's technology will generate a total of 410 MW and use both parabolic trough (Extresol, Vallesol and Casablanca in Spain) and central receiver (in Crescent Dunes Energy, in Tonopah, Nevada, USA) technologies. Water installations in concentrated solar power plants collect and treat raw water to feed demineralized water to the steam generation turbine, reserving a small amount for cleaning the solar panels and to supply drinking water for consumption by plant personnel. The processes employed vary wildly depending on the quality of the raw water – in its facilities, TEDAGUA has used lamellar settling, sand filtration, ultrafiltration, electrodeionization, reverse osmosis, ion exchange resins, etc. Tedagua has provided its technology to 10 concentrated solar power plants with a total utility water production capacity of 60,000 m³/day plus 5,000 m³/day of demineralized water."
