Abstract
VARIATIONS in the biological activity of activated sludges have been ascribed to a number of causes, and attempts have been made to relate the presence of characteristic organisms to the activity of the sludge. Reynoldson1 found that under the conditions existing at the Huddersfteld Sewage Works, the logarithm of the Vorticella count in the activated sludge closely followed its biological activity, as measured by the purity of the effluents produced.
