THE APPLICATION OF FeO/H2O2 FOR COLOR REMOVAL

(SGEM Scientific GeoConference, 2008, S. Sahinkaya, A. Aygun, M. F. Sevimli)

Show more

The decolorization of C.I. Reactive Orange 36 (RO 36) by using Fenton-like process (Fe0/H2O2) was studied. Batch experiments were carried out for investigation of optimum operational conditions such as pH, H2O2 and Fe0 (iron powder) dosages. The results show that Fenton-like process is an efficient process to remove color from synthetic textile wastewater including RO 36 and polyvynil alcohol (PVA). The optimal conditions were experimentally determined and it was found to be initial pH = 3, [H2O2] = 50 mg/L, [Fe0]...

At the same time the application of grey level methods for processing of digital images gives a lot of advantages. It is introduced an approach for the processing of binary images that is based on the adaptation of algorithms for grey level images like boundary detection, contour tracing, and line tinning. It is made the comparison of methods for binary filtering and corr...

ALGORITHM FOR CALCULATING THE TUNNEL PROFILE AREAS

(SGEM Scientific GeoConference, 2007, D. Barkovic, M. Zrinjski, L. Redovnikovic)

Show more

Building a tunnel is a very expensive construction task, especially when cutting a tunnel in inconvenient geological conditions. The tunnel building is made drastically more expensive by badly executed works on the cutting itself, i.e. the excavation, and it happens when the areas of excavation cross-sections differ from the areas of designed profiles. It is therefore very important to monitor, apart from the direction of tunnel cutting in terms of position and height, also the areas of cross sections of the excav...

AN EVALUATION OF ENVIRONMENTAL POLICY AND ITS MACROECONOMIC IMPLICATIONS

(SGEM Scientific GeoConference, 2007, CH. Rault, R. Sova, A. M. Sova)

Show more

One of main concern of policy makers is pollution and hence the improvement of the environmental quality. The implementation of environment policies aims at improving life and product quality in order to replace those obtained by high polluting processes by less polluting ones. Countries having more strict environmental regulations are likely to suffer from a significant increase of their production costs. As a consequence these countries become less competitive on the international market and may lose their marke...

ANAEROBIC TREATMENT OF AZO-DYE UNDER BATCH CONDITIONS

(SGEM Scientific GeoConference, 2007, M. Dursun, KARATAS S.)

Show more

Anaerobic treatment system was used for determination of colour removal under batch conditions. Azo-dye (Reactive Black 5, RB 5) with glucose as a carbon source was used as a synthetic wastewater. The decolourization process follows first order kinetics with respect to RB 5 azo-dye concentration in batch conditions. Decolourization rate constant (k1) value for dye concentration of 150mgL-1 was 0.1751 h-1 in the batch experimental study performed with RB 5. Maximum Reactive Black 5 removal efficiency was obtained a...

APPLICATION MSWR REGRESSION IN DETERMINING Pb AND Zn ANOMALIES IN MOGHANJEGH, NW IRAN AND COMPARE ITS RESULTS ITH CLASSIC REGRESSION TECHNIQUES

(SGEM Scientific GeoConference, 2007, A. Habibnia, A. Hezarkhani)

Show more

Regression analysis is a well-established method to correct for grain size differences in suites of sediments. However, distortion caused by the presence of outliers and imprecision in both variables can hinder many common regression models from performing adequately. Median sum of weighted residuals (MSWR) regression is strongly outlier-resistant and accounts for imprecision in both variables for each member of a dataset. In a case study of Ni and Pb normalization for a suite of stream sediments in NW Iran, the a...

APPLICATION OF GIS BASED MODELLING FOR STONE AGGREGATE POTENTIAL IN DALMATIA, CROATIA

(SGEM Scientific GeoConference, 2007, Z. Dedic, O. Hasan, S. Miko, B. Luksic, E. Kovacevic)

Show more

The Dalmatian region is a karst region built of Mesozoic limestone and dolomites. In the four Dalmatian counties aggregates and natural stone is quarried at 155 sites and there are 73 abandoned sites. A GIS based model on map-correlation and map-integration processes was used in order to define relationships between spatial layers and combine predictor factors in supporting a hypothesis. The response variable is the set of point locations of current aggregate and natural stone quarries (termed training sites), and...

APPLICATION OF MAGNETIC METHODS FOR ESTIMATION OF THE DEGREE OF SOIL POLLUTION IN THE AREA OF VARNA – DEVNJA INDUSTRIAL ZONE

(SGEM Scientific GeoConference, 2007, D. Jordanova, N. Jordanova)

Show more

Magnetism of soils is determined by the amount of strongly magnetic minerals, which may have different origin – inherent from the parent rocks (lithogenic); “in situ” formed during pedogenesis (pedogenic) and anthropogenic – from atmospheric deposition of particulates emitted from various industrial productions, which together with heavy metals contain also magnetic fraction. Due to the latter contribution, magnetic susceptibility of strongly polluted topsoils is significantly higher than the signal of non...

APPLICATION OF NEURAL NETWORK METHOD OF LOG PREDICTION IN PETROLEUM EXPLORATION “A CASE STUDY IN SOUTH WEST OIL FIELD, IRAN”

(SGEM Scientific GeoConference, 2007, H. Hassani)

Show more

Petrophysical evaluation is one of the important stages in petroleum exploration activities and reservoir analysis. When a log is missing in a drilling well, petrophysiests hope to deduce it from other logs available in another part of the well or in neighboring wells, in order to define true petrophysic evaluation for corresponding well. This paper presented here, is an artificial neural networks (ANNs) modeling in one of the carbonate reservoirs in the south west of Iran. In this study, three separate ANN are ap...

APPLICATION OF TOPSIS METHOD IN CONTROLLING FLY ROCK IN BLASTING OPERATIONS

(SGEM Scientific GeoConference, 2007, M. Monjezi, H. D. Jan Abadi, F. Samimi Namin)

Show more

Fly rock is one of the reluctant phenomenon in blasting operation. Several factors are effective in producing fly rock. As a whole, these factors can be divided into two groups; controllable parameters (blasting pattern) and uncontrollable parameters (geo-mechanical characteristics). One of the most important controllable parameters in blasting operation is blast hole diameter. Proper diameter is the diameter which is optimum from technical and economical point of view. Normally, statistical methods can be used fo...
