The results of the test coagulation of clarified wastewater of urban sewage facilities are presented in this work. A dose of aluminum and iron-containing coagulants in terms of metal oxide (Me2O3 ) was used as a parameter for comparison of the efficiency of reagent removal of phosphorus from wastewater. It was shown that the uses of any of the selected coagulants make it possible to bring the degree of purification of municipal effluents to the requirements of fishery co-op permissible exposure limit at the stage of simultaneous subsidence, while the best efficiency results are obtained for an aluminum oxychloride coagulant.
