There were considered the issues of wastewater treatment of soap manufacture, notably from fats, soaps and suspended solids. Conducted studies showed that the most effective wastewater treatment could be flotation method combined with settling. There was established that by using such technique there is a reduction of fat content by 10 or more times, and soaps and soaps by 4 -5 times. The proposed technology could be realized in combined flotation plant as flotation tank. Depending on type of solved issue, there could be conducted decontamination with the use of xenon flash lamps.

Target of research was waste of hydrometallurgical processing of tungsten concentrates (sheelite and wolframite) - dump cakes, stored in sludge dump of plant. The aim of work was process engineering of dump cakes processing, guaranteed extraction from its products of enrichments, that could be entirely drawing into economic circulation. In laboratory conditions with the use of gravity methods of enrichments from cakes were extracted weight fraction, enriched by compounds of tungsten and molybdenum, and light fraction, consisting basically from calcites, fluorites, quartz, iron oxides, magnesium and aluminum. Both products of separation process were possessed by properties of capital goods: the weight fraction of gravity on its quality is secondary tungsten raw material, that could be profitably reprocessed by means of existing technique at plant. There were described results of tests on compression strength of samples of heavy-weight concrete, proving the possibility of reduction by 20-30% of the cement.

There was displayed a possibility of chelating agents  application (EDTA, EDTMP) for remediation of sod-podzol soils, which were artificially polluted with by heavy metals (HM) – Cu(II), Pb(II), Zn(II), Cd(II). There was established a dependence of HM sorption on some factors (nature of metals, pH, and humic matter content in soils). There was described identical sorption behavior of low humic soils and synthetic goethite (α-FeOOH). There was studied process of soils demutualization by the action of water solutions of chelating agents under different value of pH of extract solution (pH = 2 - 10) and mole ratio reagents (chelating agent : HM = 1 - 20). There was demonstrated that the extraction by EDTA solution (twentyfold redundancy in relation to HM) during 1 - 2 hours leads to high degree of extraction of Cu (II), Cd (II) (70 – 95 % of acid-soluble forms) and less effective extraction of Pb (II) (5 – 35 %). Optimal for extraction pH of medium corresponds to range of pH of 5 - 8. Desorbed action of EDTMP was expressed more weak (in comparison with EDTA), that is connected with more strong sorption of phosphonates.

There was developed and research a new filtering medium for treatment of drinking water from iron and manganese, which contains as the base granular foam glass ceramics, obtaining by means of secondary treatment of glass scrap. There were determined physical and technical characteristics of foam glass ceramics pellets. There were conducted studies and laboratory tests of filtering medium on waters of different sources. There was draw conclusion that complex of oxides and hydroxides, obtaining on the surface of granular foam glass ceramics allows removing from water iron and manganese.

There was considered the issue of increasing of usage efficiency of buildings and facilities’ demolition as broken bricks, as well as production fault and technology of concrete manufacturing, and reducing of its producing costs in the manufacture from its light small piece of wall materials. There were described study results of products of crushing out of broken bricks and production fault of bricks production. There was investigated structure and morphology of secondary aggregate from broken bricks and fault, verified potential of its usage as small and large aggregate in the composition of light ceramoconcrete. There was established that important specific feature of such aggregate is existence of porous structure of grains, which leads to increased water adsorption of aggregate, and it is supposed usage of its in concrete mixture together with superplasticizing agents of water reducing action. There was established conformity of unique influence of secondary aggregate with increased water adsorption on processes of structure formation of light ceramoconcrete.

Removal of biogenic matter on biological treatment plants poses a problem of upgrade of withdrawal of toxicants at final step of wastewater’s tertiary treatment. There was established that adsorption-catalytic loadings of AK series are possessed by high resistant to detritions and maintained high performance during of 15 years of lifecycle. There was described comparative analysis on efficiency of wastewater’s tertiary treatment with the use of different types of filterable loading. Conducted at Cluster of mineral springs of Caucasus Sewage treatment facilities showed that obtained as removing of suspended matters both nitrogen-containing compounds, phosphates, metals.

There was considered a possibility of plastic material recovery, which are parts of solid household waste composition, by means of thermolysis with receiving of textured carbon, which could be used for example under designing. There were selected optimal parameters of synthesis process carrying-out in accordance with recommendations of literature sources. With the aid of SEM-images by taking into account physical and chemical properties of polymer waste was made analysis of unique features of thermal transformations these carbon-containing materials. On the base of EPR-measurements were received data about thermal stability of research materials.

There was investigated influence of MKAD Orbital on intake of polycyclic aromatic hydrocarbons (PAH) into ecosystems of National Park “Losiny Ostrov”. There was made analysis of content and composition of PAH on the territory of park during winter and summer period. There was examined dynamics and level of PAH intake on soil surface with leaf and brunch shedding for nondecidous aciculilignosa and decidulignosa. The most powerful source of aerial fallout of  PAH at studied territory of park is MKAD. There was demonstrated that in the range of 100 m from MKAD at forest territory of National Park “Losiny Ostrov” is formed transport abnormality with high level of aerial fallout of PAH during all year. For all points at studied territory was detected more high contribution of “light” PAH in winter aerial fallout, in comparison with summer period.

There were substantiated significance and practical importance of domestic equipment development for neutralization of ballast waters of large capacity ships, possibilities of environmentally safe methods usage for neutralization of ballast waters, namely filtration and far-ultraviolet radiation in respect to shipboard use.

Application of hyperspectral survey of earth’s surface is one of the most informative option of data using from remote sensing of the Earth. Advantage of hyperspectral images during remote monitoring of environment is connected with possibility of creation of surface’s qualification cards with isolation of similar plots, where it is possible a presence of any pollutant. In the absence of spectral standard classification of pixels on the images is carrying out “without learning”. Classification “with learning” is supposed use of database of spectral signals that substantially accelerated and simplified further work on type surface’s identification. There were obtained data of spectral signals of different surfaces that were tabulated in stand-alone library. Images obtained during flight tests were investigated with the use of different software packages, designated for topical data processing. There were determined possibilities of pollutions’ different types’ identification on the surface with the use classification “with learning”. There was carrying out test on detection of plots with presence of oil pollution
