Рассмотрено влияние природы и молекулярной массы полиэлектролитных компонентов и их соотношения в системе на эффективность и скорость процесса осаждения частиц дисперсной фазы. В качестве полиэлектролитов в работе использованы натриевая соль карбоксиметилцеллюлозы, поли-N,N-диметил-N,N-диаллиламмоний хлорид и полианионы и поликатионы на основе полиакриламида. Показано, что применение бифлокуляционных систем значительно увеличивает скорость отделения дисперсной фазы и позволяет добиться улучшения качества осветления дисперсии при значительно меньших (по сравнению с монофлокуляционными системами) расходах полимерных электролитов.</p></abstract><trans-abstract xml:lang="en"><p>The possibility and efficiency of biflocсulation systems, including polymer electrolytes capable of interaction and polyelectrolyte complexes formation, usage in the processes of water treatment for the mineral particles separation, was studied. The influence of the nature, molecular weight of polyelectrolyte components and their ratio in the system on the efficiency and speed of the dispersed phase particles deposition process was considered. Sodium salt of carboxymethylcellulose, poly-N,N-dimethyl-N,N-diallylammonium chloride and polyanions and polycations polyacrylamide-based were used as polyelectrolytes. It was shown that application biflocсulation systems significantly increases the speed of the dispersed phase separation and allows to improve the clarification quality of the dispersion with a much lower (compared to monoflocculation systems) consumption of polymer electrolytes.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>полиэлектролиты</kwd><kwd>полиэлектролитные комплексы</kwd><kwd>дисперсные системы</kwd><kwd>флокуляция</kwd></kwd-group><kwd-group xml:lang="en"><kwd>polyelectrolytes</kwd><kwd>polyelectrolyte complexes</kwd><kwd>disperse systems</kwd><kwd>flocculation</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Государственный доклад "О состоянии и об охране окружающей среды в Российской Федерации в 2017 году".
