ISO-15522 › Water quality -- Determination of the inhibitory effect of water constituents on the growth of activated sludge microorganisms
The following bibliographic material is provided to assist you with your purchasing decision:
This International Standard specifies a method for assessing the potential toxicity of a test material to the growth of aerobic bacteria present in activated sludge. The inhibitory effect is restricted to those microorganisms capable of growth on the chosen organic test medium.
This method gives information on inhibitory effects on the microorganisms over incubation periods up to 6 h.
This method is applicable to water, wastewater and chemical substances which are soluble under the conditions of the test. Special care is needed with volatile or coloured materials and materials which form turbid suspensions or dispersions.
