Main features of purification of recycled water of industrial enterprises have been considered. It has been shown that using membrane methods of purification allows to remove of dissolved metals salts from recycled water and to bring their concentration to standardized level. Using this method doesn’t require such large energy consumption as evaporation method. The analyze of membrane purification methods have been fulfilled. Mathematical model of this process has been developed. The solution algorithm has been developed and some results of simulation of membrane purification have been presented.
the method of circulating industrial waters treatment from metallurgical works with high content of phosphates is considered. It includes treatment via reagent precipitation with alkalization and flocculant addition, filtration of residue on a press-filter, further purification of water on a filter with granular loading, purification from residual calcium on an ion-exchange filter, neutralization of softened water and its final desalting in the unit of reverse osmosis.
In work considered application of baromembrane methods for waste treatment of metallurgical works, basic laws of baromembrane processes. On basis of adduced laws defined basic tasks of control system, mode of working and quality indexes of operation membrane complex.
In given report is considered automatic system operative supervisor management (ASODU) of the underground mine on extraction of diamond ore «Internacionalinyy». They are brought main functions, which execution is entrusted to this system, technical decisions prescribed in base of the work ASODU.
The article is devoted to system «Ore pretreatment» of automation of process of enrichment of factory on extraction of diamonds. Work of a site рудоподготовки and its equipment, the basic purposes and problems of introduction ASUTP «Ore pretreatment» is briefly described, the basic contours by means of which introduction, stabilization and optimization of corresponding technological parameters is reached are resulted.
