High-efficiency simultaneous treatment solution for nitric acid and ammonia.

This is a high-performance wastewater treatment device that adds a nitrate reduction function to the cathode side based on the conventional "N-FreeA system." In this system, nitrate ions (NO₃⁻) in the wastewater are first electrochemically reduced at the cathode and converted into ammonia (NH₃). Next, by reacting with hypochlorous acid (HOCl) generated at the anode, the ammonia is oxidatively decomposed to nitrogen gas (N₂). This process allows for the efficient simultaneous removal of nitrate nitrogen and ammonia nitrogen from the wastewater. Additionally, even if ammonia is already present in the raw water, both nitrate and ammonia can be treated simultaneously, enabling the safe and reliable removal of multiple nitrogen compounds in one go. 【Features】 - Capable of handling wastewater that cannot be treated by biological methods. - No dilution is required, and the high reaction speed allows for space-saving. - No secondary waste (such as sludge) is generated. - Can operate only when treatment is needed (continuous operation is not necessary). - There is no need to treat ammonia and nitrate separately. - Particularly suitable for treating wastewater with high salt concentrations (high electrical conductivity). *For more details, please refer to the PDF document or feel free to contact us.*
