TYPOMORPIC FEATURES OF PYRITE IN THE SEALS OF OIL FIELDS OF TATARSTAN

(STEF92 Technology, 2017-11-20, L.M. Sitdikova, V.G. Izotov, A.V. Vakhin)

Show more

Seals of oil deposits of Tatarstan (Volga-Ural petroleum province) are a complex geological and geochemical object. The preservation degree of hydrocarbon deposits is determined by the filtration characteristics of the seals. Migration of the identified portions of hydrocarbon compounds through the fluid lead to a violation of lithological-geochemical equilibrium in the seal. The development of pyrite in the seals is connected both with the syndiagenetic processes of sediment transformation and with biomineralogic...

Ultra clean coal (UCC) contains less than one per cent by weight ash. It is created via chemical leaching, because conventional, physical separating techniques cannot achieve this extremely low mineral content. Potential uses for ultra clean coal, apart from power generation, include for example directly fired into gas turbines пїЅ increasing the efficiency of power generation and eliminating the need for ash dams, production of graphite and carbon fibres, wood charcoal alternative for silicon smelting and others....

(Stef92 Technology, 2011-06-20, Bronislava Lalinská)

Show more

A detailed study of the weathering products is an important step toward the comprehension of the complex processes opera ting in the environment of mine tailings. The identification of the carriers of the polluta nts is a prerequisite for the assessment of the contamination risk and a remediation or immobilization strategy. In this study, we describe sulfide oxidation processes and the resulting chemical composition of the weathering products within 2 tailing impoundme nts rich in Fe, Ca, Si, Ba and Al. Content of...

ABOUT THE PRINCIPAL SOURCES OF HEAVY METALS IN THE NORTHERN DVINA RIVER ESTUARY

(Stef92 Technology, 2011-06-20, Yu. A. Fedorov)

Show more

The present research is devoted to the analysis of the results obtained during the expeditions organized to study the conten t and distribution of heavy metals in atmospheric precipitation, river waters and so ils of the Northern Dv ina basin. At this paper the results of qua ntity calculations of heavy metals (Cd, Pb , Zn, Cr, Ni, Cu, Hg) which are arriving with atmospheric precip itation, surface run-off to the river and carrying out with river discharge to the White Sea are presented.

ACID MINE DRAINAGE AS ENVIRONMENTAL RISK FOR SURFACE WATER

(Stef92 Technology, 2011-06-20, Magdaléna Bálintová)

Show more

Anthropogenic activities produce a lot of chem ical, physical and bi ological pollutants, which penetrate by different ways into environment and influence the living organisms and ecosystems negatively. In present it does not exist universal method for environmental risk assessment. Most countries use various procedures in field of risk analysis oriented to the specific problem solutions close connected with the chosen factors, which have negative influences on the individual environmental parts. The paper deals w...

The ozone layer as a protective shield life on biosphere, have very oscillations from view point of quantity and volume. To be aware on vari ation of ozon e layer volume carries out via gauging of total ozone in gauge ozone station. In this research the climatic parameter effects have been investigated on total ozone variations in Isfahan gauge ozone station and shows that a part of ozone daily oscillations are associated with atmosphere circulation patterns in upper and middle levels. My review show that the valu...

BENTONITE AND ITS MODIFIED DERIVATES AS ADSORBENTS OF LEAD

(Stef92 Technology, 2011-06-20, Lenka Fusová)

Show more

The main objective was to study the removal of lead cations from aqueous solutions by sorption onto bentonite and its modificati ons. Modification included natrification by NaCl and intercalation by octadecylamine (ODA) in two different weight ratios. The sorption isotherms were described using the Langmuir and Freundlich models. The adsorptive capacities of the or iginal bentonite increased af ter the intercalation of ODA. Adsorption of Pb ions, calculated by the La ngmuir model, yielded 97.15mg of Pb ions on 1g ...

The soil represents a triphasial poly-disperse system that can provide thriving conditions for various groups of invertebrates: aquatic organisms (protozoa, certain nematodes, rotifers) evolving in soil’s pores water f ilm, aerobic organisms (microarthropods) living in well aerated interstitial spaces with water saturation and m acrofauna (insects, larvae and lumbricidae), all generating a strong impact upon soil’s phases. The last two categories develop the greatest impact, thus their evaluation becomes of gr...

CHARACTERIZATION OF INDUSTRIAL WASTE WATER GENERATED IN THE COPPER PRODUCTION PROCESS

(Stef92 Technology, 2011-06-20, Radojka Jonović)

Show more

The biggest polluters of water resources are industrial waste water produced after various production technological processes. Within the industrial complex RTB Bor, the waste water are generated during the copper production process with negative impact on the environment, reflected in long-term contamination of soil with which they come into contact and accumulation of heavy metal ions in it, in inflow into surface water and mixing with ground water and their pollution. Directly, the most vulnerable are the Bor R...

Transport noise barriers are ecological struct ures that are designed and built along the roads (motorways, expressways and railways etc. ), in order to reduce the noise levels to the limit values for urban areas and in rooms of buildings. Assessment of the effectiveness of the barrier is carried out th eoretically, empirically or by a combination of both methods. To automate the design of th in noise barriers are created four modules from the series Screen *, which are part of the software package for acoustic ca...

DETERIORATION OF CONCRETE MATERIAL AFFECTED BY MICROORGANISMS LIVING IN THE WASTE WATER

(Stef92 Technology, 2011-06-20, Adriana Eštoková)

Show more

Concrete and mortar made with Portland cement can be damaged when exposed to solutions containing sulphate. Waste water ofte n contains sulphuric bacteria, and so the piping is frequently damage due to sulphate attack. In case of concrete sewer pipes this phenomenon is caused mainly by the sulphur-o xidising and sulphate-reducing bacteria that are forming part of the biological circulation of sulphur and its compounds in biosphere. These bacteria take part in the dissimilatory part of this cycle and the bacterial ...
