The effectiveness of various inorganic coagulants based on aluminum and iron was evaluated. Based on a review of the literature data, as well as experimental studies, the advantages and disadvantages of a number of coagulants based on aluminum and iron have been identified. Aluminum sulfate, iron sulfate, as well as polyoxychloride and aluminum oxychloride were studied. Based on the results of evaluating the effectiveness of inorganic coagulants in terms of turbidity, chromaticity, residual aluminum, permanganate oxidability, recommendations for their separate and joint use are given.

Keywords: coagulant, aluminum, iron, turbidity, chromaticity, permanganate oxidability, residual aluminum
