METHOD AND SYSTEM FOR ELECTROCHEMICAL REMOVAL OF NITRATE AND AMMONIA

摘要

An electrochemical method and system for removing nitrate and ammonia in effluents, using an undivided flow-through electrolyzer, said electrolyzer comprising at least one cell, each cell comprising at least one anode and one cathode, the cathode being in a copper/nickel based alloy of a high corrosion resistance and a high electroactivity for nitrate reduction to ammonia and the anode being a DSA electrode of a high corrosion resistance and a high electroactivity for ammonia oxidation to nitrogen in presence of chloride.
