Water quality. Determination of the elimination and biodegradability of organic compounds in an aqueous medium. Activated sludge simulation test Ingestion-build-86103 PD 6527 is an international1 Scope This International Standard specifies a method for the determination of the elimination and the biodegradability of organic compounds by aerobic micro organisms. The conditions described simulate a waste water treatment plant. Two test systems can be used: activated sludge plants or porous pots. The tests can optionally be performed under conditions of nitrification and denitrification (Annex A) and coupling of the units (Annex B). The method
