Ammonium nitrogen (NH₄⁺–N) and organic nitrogen — including amines, amides, amino compounds, and other nitrogen-bearing organics — exhibit different behavior, respond to different treatment mechanisms, and often coexist in the same stream. For polishing, reuse applications, and challenging industrial matrices, polymeric ion […]
