| Shrnutí: | Title screen Solid insoluble impurities in water represent a heterogeneous group of mechanical contaminants present in the form of suspensions or colloidal particles of various origins, sizes, and chemical compositions. Their presence significantly affects the organoleptic properties of water and may also cause complications in technological processes. This paper presents the results of experimental studies on the behavior of solid insoluble impurity particles (active and inactive metals, their oxides, carbonaceous particles, mineral components, plastics, and other impurities) in aqueous suspensions under sedimentation and flotation conditions. Generalization of the experimental results made it possible to predict potential concentration ranges of impurities in contaminated water layers using dimensionless complexes. Collective effects of particle sedimentation and flotation in the presence of multiple impurity types were identified. Mathematical expressions derived from the experimental data enable prediction of the influence of key input parameters (properties, sizes, and concentrations of impurities) on sedimentation and flotation characteristics, which significantly modify the structure of contaminated wastewater and technological water layers. The expressions obtained from the experiments can be applied to optimize purification processes, providing more accurate forecasts of impurity removal efficiency under varying conditions Текстовый файл AM_Agreement |
