BS EN ISO 7827:1996 is a European Standard that outlines a method for evaluating the "ultimate" aerobic biodegradability of organic compounds in water by analyzing the dissolved organic carbon (DOC) content. This standard provides a test procedure for assessing the potential for organic compounds to be biodegraded in aerobic (oxygen-rich) aquatic environments, which is important for understanding their environmental impact.
Key points covered by BS EN ISO 7827:1996 include:
The standard defines the scope of the test method, which is specifically for evaluating the ultimate aerobic biodegradability of organic compounds in an aqueous medium using the analysis of DOC.
Apparatus and Reagents: It describes the equipment, instrumentation, and reagents required to conduct the test, ensuring that consistent and standardized conditions are used.
Procedure: The standard provides a step-by-step procedure for performing the test, including the preparation of test solutions, inoculation with microorganisms, and monitoring changes in DOC over time.
Calculation: BS EN ISO 7827:1996 specifies the calculations needed to determine the percentage of ultimate aerobic biodegradability based on the DOC measurements taken during the test.
Reporting: The standard provides guidelines for reporting the test results, including the format and content of the test report.
This method allows for the assessment of how readily organic compounds in water can be broken down by aerobic microorganisms over an extended period, which is important for understanding their environmental impact and potential for pollution.
