Nitrate removal

 

Nitrate in drinking water is considered as a priority pollutant due to its infamous adverse influences on human health. According to the high solubility of nitrate in water, it should be eliminated by specific water treatment methods. There are several traditional methods for nitrate removal which has its own advantages and dis advantages, but due to water shortage in the world new methods are taken to the be consideration.

 Nowadays, one of the most important technology in the world for removing nitrate from drinking water is Selective Electrodialysis (SED).In this method, the pollutant inlet water flow through the specific number of anion and cation membranes causes the removing nitrate ions from the inlet stream to the condensing section and the outlet waste stream.

 Payamavaran Nanotechnology Fardanegar (PNF)  Company, as the only active company in the field of designing and manufacturing Electro Dialysis Reversal(EDR) systems in I.R IRAN, offers selective electrodialysis technology as an advanced method and a suitable solution for nitrate removal of drinking water.

 Nitrate removal of water by electro dialysis (EDR) process is performed without the necessity to any chemical additives. Using this system helps to decrease the operating costs greatly in comparison with reverse osmosis methods and ion exchange resins. Also in electro dialysis(ED) systems, nitrate can be eliminated selectively, which, unlike ion exchange resins, does not increase other water-soluble ions.

The electro dialysis denitritation system of this company under the brand name PNAN has the ability to remove over 70% of the nitrate of the inlet stream. It works with minimal energy consumption and without the need for chemical additives.

 

Features :


•    Water recovery up to 97%

•    No use of chemicals and pre-treatment in the process

•    Electricity consumption almost 0.4 kWh/m3

•    Possibility of using the waste as agricultural fertilizer regarding to its rich nitrate

•    Long shelf life of membranes more than 10 years

•    Very low operating cost compared to other methods
