ISO 15587 Acid Digestion of Wastewater Samples Testing
The ISO 15587 method is a standardized procedure used to determine the chemical oxygen demand (COD) in wastewater samples. This testing service is particularly crucial for quality managers, compliance officers, R&D engineers, and procurement professionals involved in industrial manufacturing and processing facilities. The primary objective of this test is to quantify organic matter in water by oxidizing it under acidic conditions using a strong oxidant like potassium dichromate.
The process involves several critical steps: first, the wastewater sample is treated with concentrated sulfuric acid and potassium dichromate solution, which converts all organic compounds into carbon dioxide. This digestion step ensures that only inorganic substances remain unreacted. After digestion, the excess oxidant is titrated back to its original state using an alkaline medium, typically sodium or potassium permanganate.
The chemical oxygen demand measured through this method represents the amount of oxygen required for the complete oxidation of organic matter present in a water sample under specific conditions. This value provides essential information about the quality and potential environmental impact of wastewater discharged from industrial processes. Compliance with regulatory standards such as ISO 15587 ensures that facilities maintain safe levels of pollutants, thereby protecting both human health and the environment.
The accuracy and precision of results obtained using this method are paramount for making informed decisions regarding process optimization, pollution control strategies, and waste management practices within industrial settings. By adhering to international standards like ISO 15587, organizations can ensure consistent quality across their operations globally while meeting local regulatory requirements.
