Advanced Electrodialysis Water Desalination: EDR

 

Electrodialysis (ED) is an electrochemical separation process in which ions are transferred through semi-permeable ion exchange membranes in the presence of an electrical field.  Ion exchange membranes are carrying positive or negative electrical charges in form of fixed ions. Cation-exchange membranes (contain negatively charged groups fixed to the polymer matrix) and anion-exchange membranes (contain positively charged groups fixed to the polymer matrix) are the most important types of ion exchange  membranes for ED.

 Electrodialysis Reversal, commonly abbreviated EDR, is a type of ED which involves reversing the electrical charge of electrodes after a specific interval of time. This polarity reversal helps to increase the efficiency of the membranes.

 Payamavaran Nanotechnology Fardanegar (PNF) Co. known as the first Iranian active company in improvement and localization of Electrodialysis (ED) technology, proposes ED and EDR as the best method in separating salts, removing pollutant ions such as nitrate and heavy metals from water and wastewater.

In addition to its special advantage of recovery up to 95%, very low operating costs in comparison with other methods, is another unique benefit of this method. Notably, Electricity consumption will mainly be included in the operating costs through the electro dialysis method.

 

 

Advantages of reverse electrodialysis (EDR) method:

High desalination efficiency up to approximately 95%

High longevity of membranes usage up to 10 years

No requirements to chemical additives during the process

Very low maintenance costs compared to typical methods such as reverse osmosis

 No need to pretreatment
