dissolved organic nitrogen removal during water treatment

Dissolved organic nitrogen removal during water treatment

Research in the drinking water field over the past quarter of a century has focused on dissolved organic carbon (DOC), thus avoiding potential issues associated with dissolved organic nitrogen (DON). Natural organic matter (NOM) contains roughly 40–60% carbon by weight and 1–5% nitrogen by weight ( International Humic Substances Society ).
