Water quality. Test for inhibition of oxygen consumption by activated sludge for carbonaceous and ammonium oxidation has-hardcopy Why should you use BS1 Scope This International Standard specifies a method for assessing the inhibitory effect of a test material on the oxygen consumption of activated sludge microorganisms. This method is intended to represent the conditions in biological waste water treatment plants. It gives information on inhibitory or stimulatory effects after a short exposure (usually 30 min up to 180 min or even more) of the test material on activated sludge microorganisms. This
