DURING recent years, there has been increasing amount of evidence regarding the importance of protozoa in the aerobic purification of sewage1–4 and, more recently, some quantitative observations on protozoa in determining the condition of sludge and quality of effluent have been recorded5–10. The evidence so far obtained has, however, been only indirect, chiefly owing to the difficulty in separating the protozoa from the associated bacteria. This has now been achieved and the object of this note is to show that the isolated protozoa can bring about practically all the changes associated with the purification. The part played by the bacteria is almost negligible.
