The experience of operation of water treatment facilities in the regions of Russia , the Baikonur Cosmodrome , in Kazakhstan, Uzbekistan and a number of foreign countries, built on the basis of technologies of membrane treatment of natural and wastewater developed by specialists of FSUE "Keldysh Center" and equipment for their implementation. The results of studies of microfiltration track membranes in model and full-scale conditions are presented, examples of created pilot-industrial microfiltration plants. are given. The mathematical models developed for the selection of optimal process modes, as well as the results of the development and implementation of the technology of membrane desalination of water of the Caspian Sea, on the basis of which the largest in the CIS Mangistaus desalination plant in Russia is built. Aktau, Republic of Kazakhstan. The membrane technology of deep desalination of brackish mine waters is illuminated, providing for the production of demineralized water, anhydrous sodium sulfate and other mineral salts. For professionals, graduate students and students engaged in the field of water preparation for economic, drinking and industrial purposes and ecology .
