Includes bibliographical references (leaves 264-279). / Eutrophication of water supplies has necessitated the development of methods to prevent discharge of excessive quantities of nitrogen and phosphorus. Operation of a generally applicable process for removing these elements from sewage effluents has not yet been reported. The investigations described here were carried out to determine the feasibility of using the nutritional requirements of controlled ecological systems for this purpose. The results are presented as an alternative approach to the chemical methods that have received consideration.
