Water quality. Evaluation of ultimate aerobic biodegradability of organic compounds in aqueous medium by determination of oxygen demand in a closed respirometer Ingestion-build-177197 They are described from theWhat is ISO 9408 Aerobic biodegradability of organic compounds in aqueous medium about? ISO 9408 is an International Standard that specifies a method, by determination of the oxygen demand in a closed respirometer, for the evaluation in aqueous medium of the ultimate biodegradability of organic compounds and wastewaters at a given concentration by aerobic microorganisms. The method applies to organic compounds which: Are water soluble under the
