The thesis is devoted to creation a scientific basis for application and regulation of the separating properties of the newest tubular microfiltration membranes developed by us from natural materials - ceramic (from clay minerals) and lignocellulose (from wood) by their modification for environmentally water purification from inorganic and organic impurities of natural and anthropogenic origin to the normativ values of her quality. Ecological expediency of modification of domestic microfiltration membranes from natural materials with metal hydroxides (Fe(III), Al(III), Zn(II) and Cu(II)), hydroxides and oxides of Mn, clay minerals is substantiated for the purpose of increase of efficiency of microfiltration water purification from connections these metals, fluoride ions, natural organic compounds, dyes, and determined the conditions for the formation on the surface of ceramic and lignocellulosic membranes of dynamic membranes, providing maximum removal of contaminants while maintaining their high specific productivity. Experimental baromembrane installations with domestic microfiltration ceramic membranes made of clay minerals have been tested, and technological parameters have been established for the processes of purifying natural water from different sources and spent detergent alkaline solution of the Banknote-Mint of the National Bank of Ukraine from compounds of natural and anthropogenic origin. Based on the results of a comprehensive biotesting it was confirmed that genetically safe Dnieper water purified with ceramic membranes from clay minerals was obtained.
