ISO 5667-21 Sampling of Suspended Solids in Wastewater: Laboratory Testing Services Provided by Eurolab

ISO 5667-21 is an international standard that outlines the requirements for sampling suspended solids in wastewater. The standard is part of the ISO 5667 series, which covers water quality sampling. The standard was published in 2006 and has since been adopted by many countries around the world.

Relevant Standards

  • ISO 5667-1: Water quality - Sampling - Part 1: Guidance on the design of sampling programmes

  • ISO 5667-3: Water quality - Sampling - Part 3: Guidance on the preservation and handling of water samples

  • ISO 5667-6: Water quality - Sampling - Part 6: Guidance on sample collection, storage, and transport

  • ASTM D7345: Standard Practice for Sample Collection and Preservation of Wastewater

  • EN 25852: Water quality - Sampling - Particular requirements for the analysis of suspended solids in wastewater

    • Legal and Regulatory Framework

    The ISO 5667-21 standard is used to ensure that wastewater samples are collected, stored, and transported in a way that preserves their integrity. This is particularly important for regulatory compliance purposes. Many countries have laws and regulations that require wastewater treatment plants to test for suspended solids.

    In the European Union, for example, the Water Framework Directive (2000/60/EC) requires member states to implement measures to prevent pollution from industrial activities, including wastewater treatment plants. The directive sets out specific requirements for water quality monitoring, including sampling and analysis of suspended solids.

    International and National Standards

    The ISO 5667-21 standard is widely adopted around the world. In addition to the countries that have officially adopted the standard, many others use it as a reference or guide for their own national standards.

    In the United States, for example, the Environmental Protection Agency (EPA) uses the ASTM D7345 standard for sample collection and preservation of wastewater.

    Standard Development Organizations

    The International Organization for Standardization (ISO) is responsible for developing and maintaining the ISO 5667 series. The ISO is a non-governmental organization that brings together experts from around the world to develop standards.

    Other organizations, such as the American Society for Testing and Materials (ASTM) and the European Committee for Standardization (CEN), also play important roles in standard development.

    How Standards Evolve and Get Updated

    Standards are constantly evolving to reflect changes in technology, science, and society. The ISO 5667-21 standard is reviewed and updated regularly to ensure that it remains relevant and effective.

    When a new edition of the standard is published, existing users must update their procedures to comply with the new requirements. This can be time-consuming and costly, but it ensures that wastewater sampling and analysis are carried out in a way that preserves water quality.

    Standard Compliance Requirements

    Compliance with ISO 5667-21 requires that wastewater treatment plants follow specific guidelines for sample collection, storage, and transport. These include:

  • Using certified equipment for sampling

  • Following proper procedures for handling and transporting samples

  • Ensuring that samples are preserved in a way that prevents contamination or degradation

    • Failure to comply with these requirements can result in inaccurate test results, which can have serious consequences for water quality and public health.

    Why is ISO 5667-21 Necessary?

    ISO 5667-21 is necessary because wastewater treatment plants require accurate information about the suspended solids content of their effluent. This information is critical for ensuring that treatment processes are effective and that water quality meets regulatory standards.

    Without accurate data, treatment plants may not be able to identify problems or optimize their operations, which can lead to environmental and health impacts.

    Business and Technical Reasons

    There are several business and technical reasons why ISO 5667-21 testing is necessary:

  • Ensuring compliance with regulations

  • Protecting public health and the environment

  • Optimizing treatment processes and reducing costs

  • Improving product safety and reliability

    • Consequences of Not Performing this Test

    Failure to perform ISO 5667-21 testing can have serious consequences, including:

  • Inaccurate test results

  • Non-compliance with regulations

  • Environmental and health impacts

  • Financial losses due to inefficient treatment processes or equipment failure

    • Industries and Sectors that Require this Testing

    Many industries and sectors require ISO 5667-21 testing, including:

  • Wastewater treatment plants

  • Industrial water users (e.g., textile mills, chemical manufacturers)

  • Municipalities and local governments

  • Environmental monitoring agencies

    • Risk Factors and Safety Implications

    Performing ISO 5667-21 testing requires careful attention to safety protocols and risk management. This includes ensuring that sampling equipment is properly maintained and used, and that samples are handled and transported in a way that prevents contamination or degradation.

    Failure to follow these procedures can result in serious accidents or environmental damage.
