The aim of the work is the maximal use of specific properties of cationic polyelectrolytes for extraction of polydisperse impurities from aqueos media. The experimental researches were carried out by the methods of surface chemistry using the laboratory models of bubble-film water-purifiers, which were created in the process of the previous research work. The extraction kinetic of polydisperse impurities from water was investigated. Here water circulated through the granular mass with a surface, saturated with adsorbtion olygomers monolayers of cationic surfaсe-active polyelectrolytes. The physical-chemical and hydrodynamical effects followed by the appearance of polyelectrolite film on granulated mass are investigated. The physical and mathematical model of circulating heterocoagulation on granular mass and the model of combined process of circulating heterocoagulation and activated bubble-film extraction is developed and experimentally examened. It was tesed on polydisperse compounds of iron, silica-aluminium and other substances which intensively turbid aqueous media. It was developed the demonstration laboratory device where heterocoagulation and bubble-film processes occur simultaneously and without additional energy consumption. The possible application area - water treating, public health services, food-processing industry Product Description popup.authors popup.nrat_date 2020-04-02 Close
