Tkachuk N. Improving the process of adsorptive purification of drinking water and aqueous-alcoholic solutions

The dissertation is dedicated to the improvement of the processes of adsorptive purification of drinking water and aqueous-alcoholic solutions by domestic natural adsorbents. Kinetic curves of adsorbing ions of ferum and ammonium nitrogen by the analyzed natural adsorbents have been obtained. The author has established the adsorptive capacity of paligorskite, glauconite, mordenite with regard to heavy metals, radionuclides, colonies of harmful germs and suggested the groundings for sorption mechanisms which concurrently take place. Curves for adsorbing ions of ferum and ammonium nitrogen in water and adsorbent have been plotted. Mathematic model for adsorptive processes has been developed on the basis of diffusive model, program for its solution has been suggested, its adequacy has been checked. The obtained results have been used when elaborating the construction of adsorption device, used to improve the technological scheme for producing drinking water. The physical constants and kinetic characteristics of adsorptive impurities from water by paligorskite have been calculated. The effective adsorbent for processing aqueous-alcoholic solutions - glauconite - has been selected. The optimization for the process of adsorptive purification of aqueous-alcoholic solutions by glauconite has been performed and equation of regression for the theoretical calculation of aldehydes, adsorbed from the solution, has been worked out. Equipment and technological schemes for adsorptive purification of drinking water and aqueous-alcoholic solutions have been improved and their economic efficiency has been substantiated. Key words: natural dispersive minerals, adsorptive purification, drinking water, aqueous-alcoholic solutions, physical constants, kinetic characteristics, mathematic modeling, optimization.
