Abstract One of the nuisance conditions brought about by the impact of civilization on some regions is the accelerated eutrophication of receiving waters, especially of stagnant waters, owing to the increased supply of plant nutrients from industrial and municipal wastes. To counteract this situation it is recommended that effective measures be taken to reduce the supply of phosphorus and, in part, nitrogen to such waters. Insofar as the supply of these elements stems from communal wastewaters this objective can be achieved by extensive purification. While the most suitable method for removal of nitrogen is nitrification and denitrification, that which recommends itself for the removal of phosphorus is the method of phosphate precipitation, a well established, economic technique which can be employed in existing plant. The success of the measures taken, however, depends to a large extent on achieving wastewater having a very low phosphorus content.
