EN 25813 Ammonium by Flow Injection Analysis
The EN 25813 method for determining ammonium in wastewaters and effluents using flow injection analysis (FIA) is a critical tool for environmental quality management. This technique is widely employed to ensure compliance with stringent wastewater discharge limits set by regulatory authorities such as the European Union.
Flow Injection Analysis is an automated analytical procedure that allows continuous measurement of chemical parameters in liquids. It is particularly advantageous for ammonium testing due to its high throughput and precision, making it suitable for routine monitoring in industrial processes and municipal waste treatment facilities.
The method involves introducing a sample into the flow stream where reagents are added, followed by a reaction mixture that generates a measurable signal indicative of the amount of ammonium present. The generated signal is then detected by a photometer or other appropriate detection device. This process provides rapid results and ensures accurate quantification.
Compliance with EN 25813 is essential for industries involved in wastewater treatment, such as food and beverage manufacturers, textile dyeing and finishing plants, paper and pulp mills, and chemical processing facilities. Non-compliance can lead to significant financial penalties and reputational damage. Therefore, reliable testing methods are critical for maintaining operational efficiency.
The procedure described in EN 25813 ensures that the results obtained from ammonium analysis are consistent with international standards. This consistency is vital for ensuring accurate assessment of a facility's environmental impact and for providing data that can be used to improve processes and reduce emissions.
For industries operating under stringent regulatory frameworks, the EN 25813 method provides a robust foundation for compliance. By adhering to this standard, facilities demonstrate their commitment to sustainable practices and responsible resource management.
| Parameter | Description |
