ISO 7827:2010 Water quality - Evaluation of the ready, ultimate aerobic biodegradability of organic compounds in an aqueous medium - Method by analysis of dissolved organic carbon (DOC)
standard by International Organization for Standardization, 11/01/2010

Full Description
ISO 7827:2010 specifies a method for the evaluation of the ready and ultimate biodegradability of organic compounds at a given range of concentrations by aerobic microorganisms. In this context, ISO 7827:2010 also gives specific definitions for the terms ready and ultimate.
The method applies to organic compounds which are: a) soluble at the concentration used under the conditions of the test [dissolved organic carbon (DOC) concentrations of 10 mg/l to 40 mg/l]; b) non-volatile or having a negligible vapour pressure under the conditions of the test; c) not significantly adsorbable on glass and activated sludge; d) not inhibitory to the test microorganisms at the concentration chosen for the test.
The method is not suitable for waste waters, as they usually contain significant amounts of water-insoluble organic carbon, which is not included in DOC measurements.
