  • The impact of temperature on the degree of structurization of water of
           different isotope composition
    • Authors: V. V. Goncharuk; I. Yu. Romanyukina; M. D. Skil’skaya; A. I. Marynin; A. V. Syroeshkin; S. A. Dolenko
      Pages: 185 - 190
      Abstract: Using vacuum ultrafiltration radiation and the method of dynamic light scattering employing samples of light (D/H = 6 ppm), distilled (D/H = 150 ppm ) water and the water with an increased content of deuterium (D/H = 7700 ppm, 99.96%) as an example within the interval 4–80°C the impact of temperature on the degree of water structurization of the different isotope composition was studied. Experimentally has been established the sizes of optical inhomogeneties of studied waters at various temperatures. It has been shown that temperature relationships of these types of water obtained by these methods have a graded nature with clear-cut critical points at 4; 36; 45 and 60–70°C.

  • Assessing the degree of water belonging to a set class of quality
    • Authors: O. M. Rosental; L. N. Aleksandrovskaya
      Pages: 191 - 196
      Abstract: The article has investigated the function of water belonging to the set class of quality by established indicators of the composition and properties. It has been shown that the employment of the mathematical apparatus of the tolerance measuring control allows using Taguchi and Harrington functions to assess the degree of the sought-for belonging both within the boundaries of the allowable interval and outside it, thereby increasing the informational content of control and monitoring. A special attention is given to problems of assessing the function of belonging in classification of waters having indefiniteness zones between classes. The proposed methods are used in treatment of real statistical data characterizing water quality. Algorithms of treatment are methodological recommendations facilitating the employment of the developed approach for solving practical problems assessing the composition and properties of water with the aim of water use.

  • Tobacco ore of the Kerch iron-ore basin as a sorbent for removing 90 Sr
           from water medium
    • Authors: A. A. Kosorukov; S. A. Kobets; G. N. Pshinko; V. M. Fedorova; V. Ya. Demchenko
      Pages: 203 - 208
      Abstract: The paper investigates sorption removal of 90Sr from water media by the tobacco ore of the Kerch iron-ore basin. It has been found that effective sorption is observed within the pH interval 6–9, the limit value of adsorption of strontium ions calculate by means of the Langmuir equation constitutes 17.95 mg/g. It is shown that sorbent efficiency for the removal of 90Sr from water is determined, in the first place, by their salt composition—nature of macrocomponents characteristic for water media (Na+, K+ and Ca2+) and their concentration.

  • Destruction of hydrocarbons by the composite system based on the
           nanosilicas and yeast cells mixture in aqueous medium
    • Authors: N. Yu. Klymenko; I. V. Siora; E. A. Novikova; A. P. Golovan; T. V. Krupskaya; L. A. Suvorova; V. V. Turov
      Pages: 209 - 213
      Abstract: The composite system based on the mixture of nanosilicas and yeast cells was investigated. It has been found that the optimal ratio of hydrophilic and hydrophobic nanosilicas as part of the nanocomposite is 1 : 1 with the yeasts amount of 50%. The nanosilica presence in the nanocomposite results in the increase of the yeast cells biomass by 2.5 times at the solid phase concentration 0.5 g and by 6 times—1 g. Thus, studied nanocomposite is an effective biodestruction agent of motor oil hydrocarbons in the aqueous medium.

  • Hybrid adsorbents based on hydrated oxides of Zr(IV), Ti(IV), Sn(IV), and
           Fe(III) for arsenic removal
    • Authors: T. V. Mal’tseva; E. A. Kolomiets; S. L. Vasilyuk
      Pages: 214 - 219
      Abstract: Synthesized are hybrid organoinoragnic adsorbents based on organic resins Dowex SBR-P, Dowex Marathon II and hydrated oxides Zn(IV), Ti(IV), Sn(IV) and Fe(III). Specific conductivity was measured of the specified resins and hybrid organoinorganic adsorbents in the initial form and after absorption of ions As(V) from 10–2 M aqueous solution of NaH2AsO4. Introduction of hydrated tin oxide increases ionic conductivity of organic resin Dowex SBR-P by 2.5 times. During the conversion to the arsenate form the conductivity of hybrid adsorbents changes insufficiently at the adsorption from the solution with pH 7 and increased by 2–10 times at adsorption from the solution with pH 2.

  • Fabrication and optimization of Cu(II) ion selective membrane electrode
    • Authors: T. A. Rangreez; Inamuddin; A. M. Asiri
      Pages: 220 - 227
      Abstract: In this study, the fabrication, performance characteristics and application of a Cu(II) ion selective pyridine based thorium(IV) phosphate membrane electrode are studied. The membrane electrode exhibited a fast response time of 10 s, the wide linear response in the concentration of 1 × 10–1 to 1 × 10–7 M of Cu (II) ions with a slope of 27.60 mV/decade change in concentration and a lifetime of 4 months. The potentiometric response revealed that the potentials are independent of pH in the wide range of 3.0–6.5. It was also used as an indicator electrode in the potentiometric titration of Cu(II) ions using ethylenediamine tetraacetic acid, disodium salt.

  • Sorption thermodynamics of organic pollutants onto zeolitic tuff:
           Isosteric and standard enthalpy
    • Authors: P. Vanore; E. Coppola; P. Iovino; V. Leone; S. Salvestrini; S. Capasso
      Pages: 228 - 232
      Abstract: The isotherms of sorption of six organic pollutants (benzyl alcohol, phenol, cyclohexanol, o-xylene, toluene and cyclohexane) from water solutions onto a zeolitic tuff (Si/Al ratio = 2.4) have been determined by batch experiments at 4; 14; 24 and 34C. Sorbitivity (amount of solute sorbed per unit dry mass sorbent at the equilibrium) was very low for all molecules tested, particularly so for the hydroxyl compounds. Comparison of Freundlich parameters and the values of isosteric and standard enthalpy as determined in the present study with analogous data for immobilized humic acid and humic acid-zeolite adducts confirms that the sorbing properties of the adducts are not the sum of its components.

  • Microfiltration treatment of domestic wastewater
    • Authors: O. O. Seminskaya; M. N. Balakina; D. D. Kucheruk; V. V. Goncharuk
      Pages: 233 - 236
      Abstract: The microfiltration of domestic wastewater on tubular microfilters based on clay minerals and oxide ceramics has been studied. The mechanism of the process according to which microfiltration is performed with consistent transition from filtering with gradual clogging of each pore by many particles to filtering with formation of sediment on the microfilter surface was established. A positive effect of filtering through the granular media before microfiltration was also shown.

  • Difficulties in the anammox process start-up in sequencing batch reactor
           at low temperature
    • Authors: P. Gutwinski; G. Cema
      Pages: 237 - 244
      Abstract: A promising technology offering significant environmental benefits compared to classical nitrification/denitrification processes appears to be the partial nitrification/Anammox that can be carried out in a one single reactor. In this paper the results of start-up of the CANON process in two lab-scale Sequencing Batch Reactors with continuous and batch flow, at low temperature (20 ± 2°C) were presented. The results indicate that the CANON process in its initial phase is characterised by high instability. It was showed that the system needs the intensive control of basic technological parameters and that the temperature of 20 ± 2°C is insufficient for the fast start-up of the CANON process. During first four months of the research, the stable CANON process was not achieved. Further analysis on this pilot-scale system showed that Anammox appeared after about 5.5 months. Results also showed that dissolved organic and free ammonia is the key factor to start-up CANON process.

    • Authors: A. N. Mikheev; O. V. Lapan; S. M. Madzhd
      Pages: 245 - 249
      Abstract: A mobile design of bioplateau has been developed for aqueous media treatment from radionuclides. The biotic component of bioplateau consists of land plants. The screening of promising species of higher land plants was conducted, and their capacity to accumulate 137Cs ions was determined experimentally under conditions of water culture. This capacity was compared with the accumulating capacity of aquatic macrophytes. A set of experiments with several types of substrates for seed sprouting and growth of higher land plants was conducted under the aquaculture conditions. Mini-bioplateaus were designed and their absorbing capacity in relation to radiocesium was determined.

  • Efficacy of seagrass Cymodocea rotundata beads on the removal of excessive
           nutrients in shrimp aquaculture wastewater
    • Authors: G. N. Soumya; N. Manickavasagam; P. Santhanam; S. Dinesh Kumar
      Pages: 250 - 255
      Abstract: The aim of present study is to ascertain the effects of pH, retention time, biomass dosage in beads and beads density on nutrients (Phosphate and Nitrate) uptake efficiency of seagrass Cymodocea rotundata beads in aquaculture effluent. This study was carried out in shake flask at different pH viz. 5; 6; 7; 8 and 9, and different retention time such as 30; 60; 90 and 120 min. The seagrass biomass dosage was tested with 0.1; 0.5 and 1.0 g and beads density of 25; 50; 75; 100; 125 and 150 nos. These results revealed that the optimum pH for maximum uptake of phosphate and nitrate was 7. The overall maximum nutrient uptake was noticed in 50 number beads density where the nitrate concentration decreasing from 2.05 to 0.51 μmol/L and phosphate 1.203 to 0.31 μmol/L. On considering the effects of pH, biomass and retention time, the maximum nitrate reduction (3.85 μmol/L) was found at pH 7 in 120 min at 0.1 g biomass dosage. The high phosphate removal (0.68 μmol/L) was found at pH 7 in 120 min at 0.1 g biomass dosage. Whereas in case of biomass dosage in beads, the maximum nutrients removal were noticed at 0.1 g among the dosage tested.

           nanoparticles of molybdenum dichalcogenides
    • Authors: T. A. Dontsova; L. M. Kulikov; I. M. Astrelin
      Pages: 132 - 137
      Abstract: The article presents the results of sorption-photocatalytic investigations into the properties of dichalcogenides of molybdenum. It has been found that properties and characteristics depend on dimensional factor, type of illumination, the pH of the solution and preparation of photocatalyst samples. It has been shown that the dimensional factor substantionally affects sorption-photocatalytic properties: in transfer from micron powders to graphene nanoparticles the specific capacity of the latter with respect to methylene blue increases two-fold as compared with micron analogues. The obtained data indicate good prospects of using graphene-like dichalcogenides of molybdenum as photocatalysts.

      Pages: 138 - 142
      Abstract: The article has investigated the process of removing U(VI) compounds from water media by layered double hydroxides [MgII//[FeIII] with different molar relationship in a brucite layer (2: 1; 3: 1; 4: 1) as well as by products of their heat treatment at 400°C. The paper has also shown high efficiency of purification of water of various composition of compounds U(VI) by the given sorbents within broad interval of the pH (2.5–9).

  • The synthesis of activated chlorine in an electrodialyzer with a tube
           ceramic membrane and a titanium–dioxide–manganese anode
    • Authors: S. Yu. Bashtan; R. D. Chebotareva; S. V. Remez
      Pages: 143 - 147
      Abstract: The article has investigated the impact of the design of an electrodialyzer with a little soluble titanium–dioxide–manganese anode and a ceramic membrane separating electrode spaces, on the concentration of chlorate–ions when producing sodium hydrochlorite. It has been shown that the location of the anode inside a ceramic membrane makes it possible to obtain sodium hypochlorite without an impurity of chlorite–ions.

  • The impact of surface properties of modified pine bark on the mechanism of
           sorption of heavy metals from aqueous media
    • Authors: O. P. Khokhotva; L. J. Westholm
      Pages: 148 - 154
      Abstract: The surface properties of pine bark before and after the treatment with urea solution and the adsorption of Cu(II), Ni(II) and Zn(II) from aqueous solutions at different pH values have been studied. Types of active sorption sites, their surface concentration and change after the bark treatment with urea solution were determined. The results of potentiometric titration were processed by using ProtoFit and FITEQL software programs. The data obtained make it possible to conclude that in the extraction mechanism of heavy metals from water the share of ion exchange decreases and the share of complexation increases. The impact of alkaline and alkaline earth metals in the range of their concentrations up to 3000 mg/dm3 on Cu(II) extraction from model aqueous solutions was also investigated.

  • Effect of current density and oil concentration on hydrodynamic aspects in
           electroflotation column during oil/water emulsion treatment
    • Authors: R. Issaoui; I. Ksentini; M. Kotti; L. Ben Mansour
      Pages: 166 - 170
      Abstract: The objective of this work is to study the efficiency of electroflotation process by treatment of effluent from vegetable oil refining industry in the form of oil–water emulsion. We will interest in hydrodynamic aspects in electroflotation columns. We will study the effect of current density and oil concentration on bubbles diameter, bubbles rise velocity, Reynolds number and the effect of the latter on the efficiency of the oil recovery. To evaluate bubble’s characteristics we used the method of video recording followed by an image processing, view of its simplicity this method is used widely. The different bubbles flow regimes were predicted by the calculation of Reynolds number. The efficiency of the process was estimated from turbidity.

  • Processing of retentates of reverse osmosis treatment of
           phosphate-containing wastewater
    • Authors: O. O. Seminskaya; M. N. Balakina; D. D. Kucheruk
      Pages: 171 - 176
      Abstract: The possibility of processing the phosphate-containing reverse osmosis retentates has been investigated. It was established that the use of NH4Cl: NH4OH mixture with 1: 4 ratio as a source of NH4 + ions and the use of magnesium chloride as a source of Mg2+ ions ensured the phosphate removal by 95.1–96.6% at the initial pH value of reaction medium equal to 10.5–11 and precipitator component ratio PO4 3–: NH4 +: Mg2+ = 1: 1: 2.

  • The correlation of trihalomethanes with other disinfections by-products
           and fractionation of dissolved organic carbon in Dez River water
    • Authors: B. Ramavandi; S. Farjadfard; M. Ardjmand
      Pages: 181 - 184
      Abstract: This work assesses the correlation between trihalomethanes (THM) and the formation potential (THMFP) of other disinfections by-products and the fractionation of natural organic matter in Dez River water in Iran. The THMFP of Dez River water was well correlated with the haloacetonitriles (R 2 = 0.796) and haloacetic acids (R 2 = 0.907) formation potential. The most abundant fraction of natural organic matter in the river was hydrophobic acid fraction (49.4 μg/L). The study demonstrated that however the THMFP of Dez River water was relatively high but a usual waterworks could effectively reduce THMFP.
