Gebze Technology Institute Purifies Water with a New Technique

A new electrochemical reactor that exterminates disease causing elements in water is developed by the Gebze Institute of Technology (GYTE)

The system is expected to reduce the risks caused by the use of chlorine, ozone and ultraviolet (UV) lamps in purifying drinking water. Research assistant in the department of environmental engineering at Gebze Institute of Technology Özge Türkay Daglı, in her statement to Anadolu Agency (AA), said the methods that are used in current purification plants have advantages as well as disadvantages.

She pointed out the risks that are caused by chlorine, ozone and UV lamps, adding, "As it is cheap and simple, chlorine is used at purification plants in Turkey. She said ozone can be used to prevent the byproducts but ozonization is not only expensive but also its practice is challenging. She said UV lamps, on the other hand, are also expensive and not effective for viruses.

Daglı emphasized that other countries are working on alternative methods, and like GYTE, started a project to produce disinfectants using electrochemical substances. She said that producing chlorine from salty water is a known and easy method: "This system can be used by integrating it with the developing technology."

The system is based on using titanium plaques as positive and negative poles and a process of decomposition of ions in the water using a diaphragm. The scientists produced two types of water, anolyte and catholyte, with advanced features by decomposing salty water in its ions in the reactor.

The anolyte is called electroactive water and is used as a disinfectant since it has a high oxidation potential. Explaining the procedure, Daglı added that the disinfectant that is produced by only adding salt into drinking water is cheaper and more ecological than using harmful chemicals. She further said that electroactive technology is currently used in daily life in Russia and Japan.
