Iranian Scientists Develop Water Desalination Technology with Energy Generation Capability
In this technology, water purification is carried out simultaneously with the generation of electrical energy. Sodium chloride salt, the most abundant salt among the water salinity factors, is selectively removed from the water and simultaneously the energy required to light various LEDs is produced during the system recovery. This process is carried out by using nanomaterials.
The capacitive deionization method is called desalination of water by removing various salts and pollutants from it in the form of ions with the help of an electrochemical process.
Iranian scientists at the faculty of chemistry of Sharif University of Technology succeeded in designing an innovative system with an extraordinary dual function in purifying water from sodium chloride salt, the most abundant salt among the water salinity factors, selectively combined with the generation of the energy required to light various LEDs during the system recovery.
The special nanomaterials synthesized in this research, along with the unique design for producing energy from salted water, the low cost and environment-friendly nature of this technology, are the advantages of this research.
In a relevant development in December, a knowledge-based company has succeeded in designing and building a portable solar water desalination device.
“Our knowledge-based company has succeeded in designing and building a portable solar water purifier which can float on seawater, salt water, or even collected rainwater and it effectively absorbs sunlight and converts it into heat,” Farzaneh Heshmati, one of the company's researchers from Tarbiat Modarres University, told ANA.
Noting that the device maximizes the rate of water evaporation and condenses and collects the purified water by using a special technology, he said, “The final output of the device is fresh and germ-free water that is completely disinfected and suitable for drinking.”
“This device is completely solar and does not require electrical energy or moving parts like a pump to operate,” Heshmati said.
