Abstract: The article discusses the main aspects of the tertiary purification of the line from suspended solids by the methods of sedimentation. The main factors influencing the effectiveness of tertiary sedimentation have been established. The analysis of the possibilities of this method for the removal of various types of contaminants, depending on the used reagent, is carried out. Based on the analysis of the literature, it was found that during tertiary sedimentation, not only suspended undissolved impurities can be removed, but also some dissolved contaminants and pathogens. To remove pathogens, it is necessary to introduce lime before mastering. An analysis of the structures used for tertiary sedimentation of structures indicates the possibility of using classical vertical and radial settling tanks for this purpose. Tertiary sedimentation can be a fairly effective alternative to post-treatment by filtration methods.

Keywords: tertiary sedimentation, biological treatment, wastewater, pollutants, environment, treatment efficiency.
