NOM-001-SEMARNAT-2021: The Regulation That’s Revolutionizing Wastewater Treatment in the Industry with Químicos Roma

NOM-001-SEMARNAT-2021 is the official Mexican standard that regulates the permissible limits of pollutants in wastewater discharges into national water bodies.
Published as an update to the 1996 version, this new standard establishes stricter and mandatory parameters for all industries.

In other words, this regulation places Mexico’s water resources at the center, requiring that every drop of discharged water meet much more rigorous and measurable standards.

• New regulated contaminants: total nitrogen and total phosphorus.
• Tighter limits: BOD, COD, suspended solids, and fats.
• Classification by receiving body: rivers, lakes, estuaries, or sea.
• Regulation by economic activity and discharge type.

Major Changes Compared to the 1996 Version

The updated standard includes more stringent parameters and stricter monitoring requirements:

• Incorporation of key contaminants: total nitrogen and total phosphorus.
• Stricter limits for BOD, COD, suspended solids, and fats and oils.
• Classification of discharges according to the receiving body (rivers, lakes, estuaries, sea).
• Differentiated regulation by economic sector, recognizing that not all industrial discharges have the same environmental impact.

These changes require industries to transform the way they treat wastewater and adopt more advanced technologies and specialized chemical solutions.
