ISO 8191 Measurement of Chemical Oxygen Demand in Wastewater Testing Services

The measurement of chemical oxygen demand (COD) in wastewater is a critical parameter in evaluating the polluting potential of industrial effluents and municipal sewage. The International Organization for Standardization (ISO) has developed the ISO 8191 standard to provide guidelines for determining COD in wastewater samples. This article will provide an overview of the relevant standards, legal and regulatory framework, international and national standards, and standard development organizations.

International Standards

The ISO 8191 standard is part of a broader suite of standards related to water quality testing, including:

  • ISO 6060:1995 (Determination of the chemical oxygen demand)

  • ISO 5815-2:2013 (Water quality Determination of chemical oxygen demand Part 2: Closed reflux colorimetric method)

  • ISO 5821:2006 (Water quality Determination of chemical oxygen demand using high temperature oxidation)

    • National Standards

    National standards bodies, such as the American Society for Testing and Materials (ASTM), European Committee for Standardization (CEN), Turkish Standards Institution (TSE), and others, have developed their own standards related to COD measurement. Some notable examples include:

  • ASTM D1252-06: Standard Test Method for Chemical Oxygen Demand of Industrial Wastewater

  • CEN/TS 15975:2010 (Water quality Determination of chemical oxygen demand)

  • TSE EN ISO 8191:2008 (Kimyasal oksijen talebi (KOT) için ölçme yöntemi)

    • Standard Development Organizations

    The International Organization for Standardization (ISO), the American Society for Testing and Materials (ASTM), and other standard development organizations play a crucial role in developing and updating standards related to COD measurement. These organizations ensure that standards are up-to-date, relevant, and aligned with industry needs.

    Why ISO 8191 is Required

    The measurement of COD in wastewater samples is essential for:

  • Evaluating the polluting potential of industrial effluents and municipal sewage

  • Ensuring compliance with regulatory requirements

  • Optimizing wastewater treatment processes

  • Reducing environmental impact

    • Failure to measure COD can lead to:

  • Environmental pollution and harm to aquatic life

  • Non-compliance with regulations, resulting in fines and penalties

  • Inefficient wastewater treatment processes

  • Loss of business reputation and customer trust

    • The ISO 8191 standard outlines the requirements for determining COD in wastewater samples. These include:

  • Sample preparation and handling procedures

  • Testing equipment and instruments

  • Calibration and validation procedures

  • Quality control measures during testing

  • Data collection and recording procedures

  • Reporting formats and standards

    • The ISO 8191 standard describes the closed reflux colorimetric method for determining COD. This involves:

  • Preparation of a wastewater sample for analysis

  • Measurement of the samples COD using a spectrophotometer or other approved instrument

  • Calculation of the COD value based on the measured absorbance or transmittance

    • The ISO 8191 standard requires that test results be documented and reported in accordance with specific guidelines. This includes:

  • Providing a detailed description of the testing procedure

  • Reporting the test result in units of mass (e.g., mg/L or g/L)

  • Specifying any limitations or uncertainties associated with the measurement

  • Including any relevant additional information, such as sample characteristics or testing conditions

    • Why This Test Should Be Performed

    Performing the ISO 8191 Measurement of Chemical Oxygen Demand in Wastewater testing service offers numerous benefits, including:

  • Reduced environmental pollution and harm to aquatic life

  • Improved wastewater treatment efficiency

  • Enhanced regulatory compliance

  • Increased customer trust and confidence

  • Improved market access and trade facilitation
