Nitrate removal

 

Nitrate in drinkable water is assumed to be a pollutant due to its infamous adverse influences on human health. Since nitrate is present in water in solution, conventional water treatment methods can't eliminate it and cause the problem of progressive production of nitrate and its release to groundwater sources. Today, the most important technology in the world in the field of nitrate removal from drinking water is selective electro dialysis (SED).In this method, the trend of water flow through a particular number of specific anionic and cationic membranes causes the movement of nitrate ions from the inlet stream to the system to the condensing part and the outlet effluent.

Payame Avaran Fardanegar Nanotechnology Company, as the only active company in the field of designing and manufacturing electro dialysis systems in the country, offers selected electrodialysis technology as an advanced method and a suitable solution for nitrification of drinking water.
Nitration of water in the electro dialysis process is performed without the necessity to add chemicals, which decreases the operating costs greatly in comparison with reverse osmosis methods and ion exchange resins. Also in electro dialysis systems, nitrate can be eliminated selectively, which, unlike ion exchange resins, does not increase other water-soluble ions.

The electrodialysis desalination modules of this company under the brand name PNAN have the ability to remove over 70% of the nitrate of the inlet stream with minimal energy consumption and without the need for chemical additives.
