  • Sorbents with the structure of layered double hydroxides for aquatic media
           treatment from U(VI)
    • Authors: M. A. Keimirov
      Pages: 128 - 133
      Abstract: Abstract Sorbents representing the layered double hydroxides of composition [Mg4Fe2(OH)12] • CO3 •nH2O, [Zn4Al2(OH)12] • CO3 • nH2O, and also the products of their thermal treatment at 400°C intended for the aquatic media treatment from U(VI) have been investigated. It is shown that the high sorption capacity of these sorbents makes it possible to recommend them for the effective removal of U(VI) from waters having different mineral composition.

      Pages: 134 - 142
      Abstract: Abstract crystal films of manganese oxide of composite materials were investigated by the method of X-ray photoelectronic spectroscopy in the fresh and spent state. The efficiency of modification was confirmed whereby on the surface of substrates of the carbonate type forms a thin-film crystalline structure of MnO2. We have found the relationship between the structure of crystalline film and substrate nature, which affects technical characteristics of the sorbent–catalyst. The mechanism of catalytic oxidation of manganese compounds in aqueous solutions using synthesized sorbents–catalysts was defined.

  • Quality and quantitative assessment of the impact of magnetic field and
           ultra sound on water with different concentration of deuterium
    • Authors: V. V. Goncharuk; A. Yu. Kurliantseva; V. V. Taranov; L. S. Nifantova
      Pages: 143 - 148
      Abstract: Abstract The paper gives results of experimental research of changes of the dimensional spectrum of gigantic heterophase clusters of water with various content of deuterium under the effect of magnetic field. It is found that th magnetic field effect (0.6 T) results in an increase of arithmetic mean diameter of clusters for light, deionized and heavy water respectively by 21, 15 and 10%. One may observe the relationship between the content of clusters and the value and time of action of the magnetic field. Ultra sound effect (44 kHz), on the contrary is conducive to a decrease of the arithmetic mean diameter of clusters of specified waters respectively by 16; 11 and 8%.

  • Investigation of BTEX removal efficiency using the electrolytic oxidation
           and Fenton’s reaction
    • Authors: L. Li; C. Song; Y. Huang; Y. Zhou
      Pages: 149 - 157
      Abstract: Abstract The removal of benzene, toluene, ethyl benzene, and xylene (BTEX) using the electrolytic oxidation or Fenton’s reaction has been studied. The value of current and pH value were shown to produce a significant effect on electrolytic oxidation of BTEX. More than 95% of BTEX could be removed at 500 mA current within 8 hours. In the case of Fenton’s reaction it was established that more than 95% of BTEX could be removed at pH 4 with an addition of hydrogen peroxide in the amount of 12 mg/dm3. The treatment cost based on electrolytic oxidation amounted to between $0.04 and $5.1 USD/m3. For Fenton’s reaction, the treatment cost was between $0.16 and $0.65/m3. The costs of electrolytic oxidation and Fenton’s reaction were similar to the cost of electrodialysis and cheaper than the freeze–thaw and evaporation; however, these costs were higher than for air flotation and the use of anoxic/aerobic granular activated carbon.

  • Effect of impurity content on structure of living water
    • Authors: S. Hao; H. Li; X. Li; L. Li; J. Xie
      Pages: 158 - 162
      Abstract: Abstract In order to study the influence of impurities content on the water structure, Raman spectra and degrees of depolarization of different living water are measured by Raman spectroscopy, the relationship between the depolarization ratio and the impurity content in drinking water was obtained by the utilisation of computer deconvolution for the stretching vibration peak. The results showed that the intensity of different bending vibration is almost the same, and the intensity of the stretching vibration reflects different content of impurities in water. Depolarization calculation of water molecules showed that the stretching vibration is stronger than the bending vibration. The interaction of impurity ions and water molecules enhances the vibration rate of water molecules, making the symmetry of stretching vibration reduced, and leading to increased depolarization ratio. Therefore, the impurities content can be determined from the relative intensity of Raman characteristic peaks and the degrees of depolarization.

      Pages: 163 - 166
      Abstract: Abstract Modification of membranes by pyrocarbon was carried out by carbonization of polyisocyanate, celluloacetate and Na-salt of carboxylmethyl cellulose at 750°C. The water was purified of dyes by the pressure-driven method under pressure from 0.1 to 1.1 MPa. The retention coefficient and specific capacity of modified membranes for direct scarlet vary respectively from 37 to 99.99% and from 1.8 to 36 dm3/(m2 • h). For membranes with carbonized cellulose ethers the retention rate for brilliant green vary from 19 to 78.5% and the specific capacity depending on pressure and filtration time varies from 8.1 dm3/(m2 • h) to ~ 1 m3/(m2 • h).

  • Selecting model for treatment of oily wastewater by MF-PAC hybrid process
           using mullite-alumina ceramic membranes
    • Authors: M. Abbasi; A. Taheri
      Pages: 173 - 180
      Abstract: Abstract Hermia’s models for cross flow filtration were used to investigate the fouling mechanisms of mullite-alumina ceramic membranes in treatment of oily wastewaters in a hybrid microfiltration-powdered activated carbon process (MF-PAC). Results show that cake filtration model can be applied for prediction of permeation flux decline for MF and MF-PAC process up to 400 ppm PAC. The complete pore blocking model and the intermediate pore blocking model can predict permeation flux decline with time for MF-PAC with 800 and 1200 ppm PAC respectively. Average error for prediction of permeation flux with cake filtration model is 2.19% for MF process and 2.16, 2.06 and 1.31% for MF-PAC process with 100, 200 and 400 ppm PAC respectively. Also for MF-PAC process with 800 and 1200 ppm PAC, average error for prediction of permeation flux with complete pore blocking model and intermediate pore blocking model was 6.11 and 6% respectively.

    • Authors: A. V. Mamaenko; A. O. Samsoni Todorov; O. V. Zui; V. A. Yaremenko; V. V. Goncharuk
      Pages: 67 - 70
      Abstract: Abstract The paper has investigated the process of measuring power illumination for vacuum ultraviolet radiation by means of the solution of potassium iodide as a photochemical actinometer. We have investigated the formation of triiodide–ion when radiated the solution of light with wavelength 185 nm. It has been shown that obtaining hydroxyl radicals OH– at this wavelength is determined by the formation of I 3 – . The quantum yield of the process constitutes 0.165. Measuring the concentration of the obtained I 3 – we determined power illumination of a quartz lamp DRB-20 (wavelength 185 nm), which constitutes 49.2 × 10–9 E/s.

  • The use of ferrocyanide Zn/Al-hydrotalcite for the sorptive concentration
           and radiometric determination of 137 Cs in waters
    • Authors: G. N. Pshinko; V. M. Fedorova; S. A. Kobets; A. A. Kosorukov
      Pages: 77 - 82
      Abstract: Abstract A sorbent based on Zn/Al-hydrotalcite intercalated by hexacyanoferrate (II)-ions is proposed for 137Cs concentration and its further radiometric determination in natural waters. Parameters for the optimal sorptive extraction of radiocesium from waters under static conditions and direct radiometric measurements have been determined. The use of ferrocyanide sorbent is shown to provide a good potential in analytical schemes of 137Cs concentration from waters with high salt background.

  • Impact of characteristic of activated carbons on the efficiency of removal
           from water of pharmaceutical preparations of various chemical nature
    • Authors: E. A. Korzh; S. K. Smolin; N. A. Klymenko
      Pages: 83 - 88
      Abstract: Abstract The article has investigated regularities of adsorption of sulfanilamide, sulfathiazole, levamizole and procaine on activated carbons KAU and Filtrasorb F400. Within the interval of concentrations 0.1–1 mol/dm3 the series of adsorption affinity of substances under research on both carbons coincide. Adsorption values decrease in the following sequence: sulfanilamide > sulfathiazole > procaine > levamizole. It has been shown that for the removal from water of the mixture of pharmaceutical preparations with different physicochemical properties it is expedient that the combination of mainly microporous carbon sorbents have different surface chemistry.

Blends were prepared by extrusion from the melt at PS concentration from 5 to 20 fraction of total mass, %. The time of attaining equilibrium at adsorption of lead ions on the polymer surface has been found. The obtained data indicate that polymers in question were more efficient compared with others, which investigated for assessing their adsorption ability with respect to lead ions. Results of equilibrium isothermal adsorption of lead ions on the mixed PETP/PS system point out that at an increase of percent content of PS in the blend a substantial increase of adsorbed lead is achieved per unit weight of polymer adsorbent. This correlates with the type and dimensions of interface morphology of blends.

  • Impact of montmorillonate on the process of purification of waters
           containing uranium by ultra- and nanofiltration
    • Authors: A. P. Kryvoruchko; L. Yu. Yurlova
      Pages: 96 - 101
      Abstract: Abstract The article has investigated the impact of montmorillonite (natural and modified) for purification of waters containing uranium by ultraand nanofiltration. It has been shown that maximally possible uranium retention coefficient by a nanofiltration membrane was obtained when a modifier with the molecular weight 2 kDa was used. Whereas for an ultrafiltration membrane a high index of purification is achieved when using a modifier with the molecular weight 10 kDa.

  • The use of fuchsin basic for determination of bromide–ions in waters by
           the method of reflection colorimetry
    • Authors: Yu. I. Maznaya; O. V. Zui
      Pages: 102 - 105
      Abstract: Abstract Photometric technique has been developed for determination of bromide ions in waters; the technique is based on oxidation in an aqueous solution of bromide to bromine by chloramine T, concentration of bromine–derivative fuchsine basic on membrane filters and measurement of lightness of obtained colored concentrates in a thin layer by means of reflection colorimetry. The detection limit of bromide–ions constitutes 10 μg/dm3, the linearity of the calibration curve ranges from 10 to 1000 μg/dm3. The excess of chloramines T does not interfere with determination, which simplifies and reduces the analysis. The proposed technique is more sensitive, fast and simple in execution than existing standard techniques. It makes it possible to control the content of bromide–ions in waters both at the level and lower than MAC and may be used in field conditions at the site of sampling

  • The removing of selected pharmaceuticals on WWTP in the Czech Republic
    • Authors: F. Wanner; M. Vana; L. Matousova; J. K. Fuksa; D. Pospichalova
      Pages: 111 - 116
      Abstract: Abstract In this article, the results of three years monitoring of selected pharmaceuticals (diclofenac, ibuprofen, carbamazepine, salicylic acid, clofibric acid) in the wastewaters of the Czech Republic are presented. The monitoring was performed on selected Wastewater Treatment Plants (WWTP) with various treatment technology and designed capacity. The concentrations and treatment efficiency of these substances were observed in various profiles of each WWTP, including influent, mechanical pretreatment, biological treatment, effluent. The main processes of removing selected pharmaceuticals during wastewater treatment are discussed. These results are used for design wastewater treatment technology with improved treatment efficiency of these substances.

  • Impact of different frequencies in the entrapment of bacterial pathogens
           from drinking water using dielectrophoretic phenomena
    • Authors: A. Sankaranarayanan; K. M. Prabu Sankarlal; D. Raja
      Pages: 117 - 122
      Abstract: Abstract The article has investigated the removal of water borne pathogens using dielectrophoresis (DEP) filter which is energized by varying the frequency of the applied potential from 10 kHz to 2 MHz with different voltage levels of 5; 10; 15 and 20 V. Separate experiments are conducted in artificially contaminated water samples with Escherichia coli, Staphylococcus aureus and Vibrio cholerae up to 2 h. The impact of signal frequency and voltages on DEP based water treatment system has been analyzed statistically. Results have demonstrated that an AC signal of 20 V with frequency range of 500 kHz to 2 MHz is suitable to remove the tested bacterial population and the rate of removal of E. coli is the highest with a dielectrophoretic filtration efficiency of 77.1%.
