ELECTRODIALYSIS SYSTEMS
Electrodialysis is one of the advanced water treatment technologies and is a membrane filtration method that removes dissolved ions from water with the help of an electric field. In this process, water is placed between cation- and anion-selective membranes and an electric field is applied. Cation-selective membranes allow only positively charged ions (e.g., sodium and calcium) to pass through, while anion-selective membranes pass negatively charged ions (e.g., chloride and sulfate). Thus, ions are transported from one membrane chamber to another, reducing the salt concentration in the water and resulting in purified water. Electrodialysis is a particularly effective method for treating water with low to medium salinity.
This technology is used in many areas such as drinking water production, wastewater recovery and industrial process water preparation. Electrodialysis can operate with lower energy consumption compared to other methods such as reverse osmosis and is more economical, especially for waters with low salt concentrations. In addition, the long lifetime of membranes and the low use of chemicals is an important advantage in terms of environmental sustainability. However, when waters with high salt concentrations need to be treated, more suitable technologies such as reverse osmosis may be preferred over electrodialysis. Electrodialysis offers a flexible and reliable method of controlling the chemical properties of water, thanks to its customizable nature with precise settings.
