The paper has presented an analytical review of the state of the art in scientific developments and technological solutions
of nanofiltration in drinking water treatment. The article has shown the possibilities of nanofiltration and analyzed reasons
restricting its wide-scale use in drinking water supply. It has covered new approaches to the solution of problems related
to membrane fouling. 相似文献

The paper has investigated regularities of water defluorination by methods of galvano- and electrocoagulation. It has been shown that electrocoagulation ensures more effective defluorination of water than galvanocoagulation. It has been proposed to use the methods in question for removal of fluorides from concentrates being formed in defluorination of water by reverse osmosis. 相似文献

The system of the efficient monitoring of air quality for maritime cities and health resorts has been set up. A basis for
the prototype of such a system is establishment of functional links between the concentration of toxic substances in the air
and the disperse composition of sea aerosol and the surface of microlayer for every maritime region under hydrometeorological
conditions. This provides an opportunity to monitor the chemical composition of sea aerosol by its disperse characteristics
and dispersion of the surface film. 相似文献

Investigated are physical and chemical conditions resulting in the formation of the ever complex organic substances from inorganic components. We investigated a number of chemical reactions running in underwater hot volcanic sources whose result is that from inorganic compounds form various organic molecules. Catalysts of the reactions may be solid particles containing transit metals that are present in hydrothermal waters. Products of reactions of reducing carbon dioxide under these conditions are formic, acetic, pyruvic acids and also methanol. This explains the formation also of more complex organic substances playing an important role in the origin of life in the medium of hydrothermal sources. 相似文献

A critical review of hypotheses of the hydrosphere genesis has been performed. It was shown that the natural background of neutrons was insufficient for explaining the hydrosphere enrichment with deuterium. This enabled us to confirm an assumption about the atmophilic genesis of hydrosphere. Enrichment of the protoplanetary cloud matter with deuterium and, probably, lithium, beryllium and boron contributed to the formation of terrestrial planets in the Solar System. 相似文献

Investigated are working characteristics of reverse-osmotic membranes of low pressure ESPA-1 and TFC-75 in purifying aqueous solutions of phosphates in the range of their concentrations 10–490 mg/dm3. It is shown that at minor difference of selectivity of studied membranes with respect to phosphate–ions the specific capacity of the membrane ESPA-1noticeably exceeds such of the membrane TFC-75. 相似文献
