Electrodenitrification compared to best available technologies (BAT) which are: Reverse Osmosis, electrodialysis, ionic exchange resins and biodenitrification processes.
We expect to reach our commercial and business goals thanks to the significant novelties that electrodenitrification brings compared to available solutions. Currently, best available technologies are based on separation and not removal. They separate nitrate and other ions of the water in a non-selectively way producing that approximately a 20% of treated water reverses into a toxic and hazardous waste. Only biodenitrification, like the electrodenitrification, closes the nitrogen cycle.
Both technologies, electrodenitrification and biodenitrification, allow closing the nitrogen cycle again, converting nitrates in air, nevertheless biodenitrification is slow and very sensitive to temperature. On the contrary, electrodenitrification is cheaper, does not require organic matter and the machinery (and consequently investment) is significantly lower.
Besides not generating waste of difficult and expensive disposal, electrodenitrification, has a total cost savings (investment and exploitation) of around 50% compared to BAT. In this context, the advantage for customers or for suppliers of drinking water or wastewater treatment is clear.
To summarize, Electrodenitrification technology could become the best available technology in the near future because it takes several advantages from the current technologies in the market. These ones are:
Electrodenitrification technology converts the inorganic N-based contaminants into air which is non-aggressive to the atmosphere.
It does not produce any sub or by-produce at the end of the process. Other techniques require a post-treatment increasing the operational costs.
Whole waterbody is treated during the process while other techniques can only achieve 80 – 85% of the total amount.
From the economical point of view, its operation and investment costs are very competitive in front of best available technologies at the market.
The electrodenitrification technology developed by Hydrokemos, and scaled and operated with success in the Watify project, offers a clean cost-efficient alternative to remediate nitrate polluted water with the exposed advantages with respect to the best available technologies for nitrate removal, which are Reverse Osmosis, electrodialysis, ionic exchange resins and biodenitrification processes.
