Water quality. Toxicity test for assessing the inhibition of nitrification of activated sludge microorganisms Ingestion-build-64721 that is absorbed (cooling) or1 Scope This International Standard specifies a method for assessing the short term inhibitory effect of waters, waste waters or test substances on nitrifying bacteria in activated sludge. The inhibitory effect is estimated over an exposure period of usually 3 h or up to 24 h with weakly nitrifying sludge. The method is applicable to nitrifying activated sludge derived from domestic and synthetic sewage and also to sludges from industrial and mixed
