Overview
The BS EN ISO 20236:2021 standard is an essential document for professionals in the field of water quality analysis. This comprehensive standard provides detailed methodologies for the determination of key water quality parameters, including Total Organic Carbon (TOC), Dissolved Organic Carbon (DOC), Total Bound Nitrogen (TNb), and Dissolved Bound Nitrogen (DNb). These parameters are crucial for assessing the organic and nitrogenous content in water, which are indicators of water pollution and overall water quality.
Key Features
- High Temperature Catalytic Oxidative Combustion: The standard employs high temperature catalytic oxidative combustion, a highly effective method for breaking down organic compounds and nitrogenous substances in water samples.
- Comprehensive Methodology: Detailed procedures ensure accurate and reproducible results, making it a reliable reference for laboratories and water quality professionals.
- Wide Applicability: Suitable for various types of water samples, including drinking water, surface water, and wastewater.
- International Standard: As an ISO standard, it is recognized and adopted globally, ensuring consistency and comparability of results across different regions and laboratories.
Detailed Description
The determination of Total Organic Carbon (TOC) and Dissolved Organic Carbon (DOC) is vital for understanding the organic load in water. TOC represents the total amount of carbon in organic compounds present in the water, while DOC refers to the organic carbon that is dissolved in the water. These measurements are crucial for monitoring water treatment processes and ensuring the safety of drinking water.
Total Bound Nitrogen (TNb) and Dissolved Bound Nitrogen (DNb) are equally important parameters. TNb includes all forms of nitrogen bound in organic and inorganic compounds, while DNb specifically refers to the nitrogen in dissolved form. These measurements help in assessing the nitrogenous pollution in water bodies, which can have significant environmental impacts, such as eutrophication.
The high temperature catalytic oxidative combustion method described in this standard ensures complete oxidation of organic and nitrogenous compounds, providing accurate and reliable measurements. This method involves heating the water sample to a high temperature in the presence of a catalyst, which facilitates the breakdown of complex organic molecules into simpler compounds that can be quantified.
Applications
This standard is applicable in various contexts, including:
- Environmental Monitoring: Regular monitoring of water bodies to assess pollution levels and the effectiveness of pollution control measures.
- Water Treatment Plants: Ensuring the efficiency of treatment processes and the safety of treated water.
- Research and Development: Supporting scientific studies on water quality and the impact of pollutants.
- Regulatory Compliance: Helping organizations comply with national and international water quality regulations.
