Desalination
Nowadays, due to rising water demands and dwindling freshwater supplies, alternative water sources are required. Desalination of brain and brackish water has become a key solution to meet the need of increased water usage. Well water, surface water, and groundwater are major parts of water resources that can be utilized in desalination.
Desalination has become more efficient and cost-competitive on a global scale thanks to recent technological achievements. Desalination systems can be classified according to the energy sources such as; thermal, mechanical, electrical and chemical. The most important factors of choosing a desalination plant are low energy consumption, low effluent production and longevity of desalination plants.
Payamavaran Nanotechnology Fardanegar (PNF) Company, known as the first Iranian active company in the improvement and localization of Electrodialysis (ED) technology, proposes Electrodialysis (ED) as one of the useful method for desalination of brackish water . Electrodialysis is a membrane process in which ions are transported through ion permeable membranes from one solution to another under the influence of an electrical potential gradient.
The desalination systems of knowledge based enterprise; Payamavaran Nanotechnology Fardanegar (PNF) Company; under the brand name of PNAD can be designed and provided in a modular form for every capacity and input EC.
