  • The influence of interphase characteristics on the attraction of particles
           in aqueous and gaseous media
    • Authors: N. A. Mishchuk
      Pages: 61 - 67
      Abstract: Abstract The dependence of the attraction energy of particles on the formation of thin layers on their surface with characteristics different from those of dispersion medium has been investigated. It is shown that at local reduction of the water density or formation of gaseous interlayer on the surface of hydrophobic particles, their attraction at small distances substantially increases. In contrast, the formation of a thin layer of water on the surface of hydrophilic particles in the air leads to weakening of their attraction. The most pronounced effect is obtained for the energy of interaction of hydrophobic disperse particle and bubble: the interaction value and sign changes depending on the specific ratio of parameters.

  • Application of luminescence for estimating the efficiency of
           photocatalysts
    • Authors: V. V. Goncharuk; O. V. Zuy; R. V. Prihod’ko
      Pages: 68 - 72
      Abstract: Abstract Capabilities of new approaches in luminescence applications for estimating the quality of photocatalysts have been studied. Since photoluminescent processes are chain ones and initiated by free radicals, luminol and other indicators can be used to determine the efficiency of photocatalysts: the higher is the intensity of luminescent glow, the more is the number of free radicals in the system and the higher is the efficiency of photocatalyst. In some cases, by using special techniques it is possible to study the accumulation of superoxide radicals, hydroxyl radicals, and hydrogen peroxide in the system.

  • Adsorption of arsenic by hybrid anion–exchanger based on titanium
           oxyhydrate
    • Authors: Ye. O. Kolomiyets; V. N. Belyakov; A. V. Palchik; T. V. Maltseva; L. I. Zheleznova
      Pages: 80 - 84
      Abstract: Abstract The article has investigated the removal of anion–exchange forms of As(V) by organic anion–exchangers Dowex Marathon 11, Dowex SBR-P and organoinorganic anion–exchangers containing titanium oxyhydrate, from 0.2–2.0 mM solutions of NaH2AsO4 in the range of equilibrium values pH 3–10. It has been found that introduction of an inorganic component in the amount of 7 fractions of total mass, % results in non-additive (up to 50 fractions of total mass, %) increase of absorption of ions of As(V) in adsorption from weakly alkaline solutions. It was assumed that nonadditive change of the value of absorption may be caused by the influence of the negative charge of the surface of oxide component of organic anion–exchangers. It is shown that in acid media and also at an increase of the amount of the introduced titanium oxyhydrate the values of adsorption and distribution coefficient of As(V) ions approaches additive ones.

    • Authors: S. K. Smolin; O. V. Zabnieva; N. A. Klymenko; O. G. Shvydenko
      Pages: 85 - 91
      Abstract: Abstract The article has assessed current losses of porosity of activated carbon due to the existence of microbial activity in the fixed sorbent bed during the removal of 2-chlorophenol from water. Non-target losses of vacant porosity of carbon increased depending on the time of functioning the biological system. At the end of the second year the content of bioproducts in spent pores constituted 75–85%.

    • Authors: N. D. Gomelya; T. A. Shabliy; A. G. Trohymenko; M. M. Shuryberko
      Pages: 92 - 96
      Abstract: Abstract New efficient inhibitors of steel corrosion and scale formation have been developed for water circulation cooling systems. They include sodium dimethylenesulfophosphonate and sodium methylenedisulphonate. The processes of scale formation and steel corrosion in water in the presence of these inhibitors were studied. It was shown that the synthesized inhibitors in terms of the efficiency were not inferior to the most effective of well-known reagents: nitryltrimethylphosphonic acid and oxyethylidendiphosphonic acid. Compositions for preventing the scale formation in waters with high hardness (carbonate index > 70 (mg-eq/dm3)2) at < 100°C were also developed.

  • Quasichemical description of the cell death kinetics of cellular biosensor
           Spirostomum ambigua for testing the biological activity of aqueous
           solutions

      Pages: 97 - 102
      Abstract: Abstract A kinetic method of biotesting of aqueous solutions using isolated cells of unicellular organism Spirostomum ambigua has been described. A kinetic scheme of interaction of cellular biosensor with ligands based on the Michaelis-Menten mechanism was proposed. It was shown that the death rate of S. ambigua featured the Arrhenius-type dependence on temperature. The activation energy was determined for different toxicants and drugs. For many compounds the activation energy of slow stage of the process of cellular biosensor death linearly correlates with parameter DL50 for the same substances at their oral administration to laboratory animals.

  • Bioregeneration of the activated carbon layer spent in the dynamics of
           procaine biofiltration
    • Authors: E. A. Korzh; N. A. Klymenko; S. K. Smolin
      Pages: 103 - 107
      Abstract: Abstract This paper has investigated bioregeneration of biologically activated carbon (BAC) from procaine. The study has shown low efficiency (up to 25%) of desorption of procaine by aqueous solutions even at heating up to 80°C. In the course of bioregeneration media of spent BAC was recovered a small degree of adsorption capacity of the sorbent and by two times enhanced the ATP-ase activity of the biofilm, which increased the efficiency of the operation of biosorbents 2.5 and 3.25 times after respective 4 and 10 days of bioregeneration. A positive effect of bioregeneration affects further biofiltration about 1000 c.v. of the model solution.

    • Authors: C. Pongener; D. Kibami; K. S. Rao; R. L. Goswamee; D. Sinha
      Pages: 108 - 115
      Abstract: Abstract Activated carbon synthesized from the plant Mucuna prurines have been successfully used to remove fluoride from aqueous solution by adsorption method. Batch method adsorption has been studied and the adsorption was found to be very significant. Almost 96% of fluoride could be removed by adsorption. Adsorption studies of fluoride signify the fact that among the different adsorption model, Langmuir adsorption model seems to be more favorable in the present case. Different parameters like effect ofadsorbent dosage, contact time, pH and initial concentration are studied to understand the adsorption mechanism.

  • Monitoring the quality of mineral bottled water concerning to potential
           pathogenic bacteria and nitrate levels
    • Authors: H. A. Hassan; M. I. Mostfa
      Pages: 116 - 124
      Abstract: Abstract The diversity of cultured pathogenic bacteria in the bottled mineral water (BMW) was investigated using selective media. The pure isolates from these selective media, which showed hemolytic activity on the blood agar media and antibiotic resistance, were identified by 16S rRNA gene technique. The seven obtained strains were belonged to the genus Pseudomonas, Bacillus, Acinetobacter, Stenotrophomonas, and Exiguobacterium, and were mostly closed to the pathogenic strains. The increasing of ozone concentration from air-fed ozone generators eliminate the growth of bacteria included the pathogenic bacteria, but in other side it increases the amount of nitrates and nitrites in the final product of the BMW. These findings revealed that the BMW either has potential pathogenic bacteria or high levels of nitrates and all these products may effect on the health of the end user.

      Abstract: Abstract The article has investigated regularities of the process of transformation of active carbon into biologically activated carbon in the course of an effective filtration purification of water of 2-chlorophenol. In exploitation of active carbon for more than two years the contribution of the adsorption and biodestructive components to the removal of the target component was marked off. It has been shown that more than 80–85% of chlorophenol is removed biologically after four–five months from the beginning of the process.

It was shown that the electrodialysis efficiency with pristine polymer membranes decreases with time due to formation of deposit directly in the membrane pores. In contrast, the organo–inorganic membranes exhibit resistance to poisoning by organic substances, and the current yield during the electromembrane treatment can reach 95–98%.

  • Assessment of the biodegradation intensity of organic compounds in water
           using the squalene biomarker
    • Authors: M. Yu. Vozhdaeva; L. I. Kantor; A. R. Kholova; M. R. Khammatova; E. A. Kantor; N. V. Trukhanova; I. A. Melnitskii
      Pages: 33 - 39
      Abstract: Abstract An approach based on the quantitative determination of squalene biomarker by the chromato-mass-spectrometry method has been proposed for assessment of the intensity of biotransformation of organic compounds in water. The method sensitivity amounted to 5 × 10–5 mg/dm3. It is recommended to use squalene for the detection of stagnant zones in the city water distribution system and the biological activity in filtering layers of wells of infiltration water intakes and in filters for industrial and domestic water treatment. An enhanced intensity of biotransformation processes is related to the rise of squalene concentration in the tested water.

  • Study on the effect of Artemia franciscana on the uptake of Zn(II) and
           Cu(II)
    • Authors: S. Sujatha Devi; M. Sethu; P. Lalithambigai; P. Gomathi Priya
      Pages: 40 - 46
      Abstract: Abstract The toxicokinetic study was used to assess the potential of an organism for Zn(II) and Cu(II) bioaccumulation and it was ascertained using a bicompartmental model. The effect of Zn(II) and Cu(II) concentration on the kinetics parameter in Artemia franciscana were determined. In the present investigation, the uptake rate seems to be high with the time period of 72 h for Zn(II) when compared to Cu(II) by the process of bioaccumulation. The bioconcentration factor (BCF) and metal influx rate (I) was also found higher in the Artemia which was exposed to Zn(II) when compared to Cu(II), whereas BCF was inversely related to the concentration. From these parameters, we may predict the effective bioaccumulation of Zn(II) and Cu(II) using Artemia franciscana and whose kinetic parameters were found to be suited to the bicompartmental model.

  • Disintegration as a key-step in pre-treatment of surplus activated sludge
    • Authors: A. Machnicka; E. Nowicka; K. Grübel
      Pages: 47 - 55
      Abstract: Abstract This study has been carried out to investigate the effect of microwave, alkalization and freezing on surplus activated sludge disintegration (release of organic/inorganic substances into the supernatant) and mesophilic fermentation. After applying pre-treatments, chemical oxygen demand increased by 7–35 times, disintegration degree was 35–47%, proteins by 5–25, carbohydrates by 2–3, phosphates 7–22 and ammonium by 3–16 times. Disintegration by microwave, alkalization and freezing has a positive effect on the rate of sludge anaerobic digestion. Biogas production increased by: 62; 49 and 58%, for microwave radiation, alkalization and freezing, respectively. The conducted research shows that the application of disintegration as a pre-treatment of surplus activated sludge is an effective method, allowing for practical using sewage sludge.

  • Estimation of residual antibiotics in soil and underground water of areas
           affected by pharmaceutical wastewater in Lahore
    • Authors: S. Hussain; M. Naeem; M. N. Chaudhry
      Pages: 56 - 60
      Abstract: Abstract Drinking water is most essential thing for life on earth. Due to environmental pollution day by day the quality and quantity of drinking water is lowering. Ground water tables are becoming contaminated due industrial pollution. Contamination level of antibiotics namely ofloxacin (OFL), ciprofloxacin (CIP), levofloxacin (LEV), oxytetracycline (OTC), doxycycline (DOX) were quantified in soil and underground water of surrounding areas of pharmaceutical industry in Lahore. HPLC with DAD detector, C-18 column and solid phase cartridges were used to analyze antibiotic residues. In groundwater DOX has highest mean level of contamination and OFL was determined as highest contaminating pollutant in soil. Highest detected value in groundwater of OFL was 0.50, CIP and LEV 0.20, DOX 0.80, OTC 0.40 ng/L. Ground water have residual level of CIP 0.01–0.20 ng/L, LEV 0.02–0.20 ng/L, OFL 0.01–0.50 ng/L, OTC 0.02–0.40 ng/L, and DOX 0.04–0.80 ng/L. Ground water was contaminated by these residues is very important as it is source of accumulation of antibiotics to human and animal body as well as to plants.

  • Liquid–phase extraction treatment of wastewater of paint and varnish
           production facilities in the extractor with mixer
    • Authors: A. A. Gasanov; G. Z. Suleimanov; G. I. Kelbaliev
      Pages: 336 - 341
      Abstract: Abstract Liquid–phase extraction technology providing the maximum wastewater purification from such electrolyte composition components as butylglycol, phenylisopropanol, ascetic acid, and acetylacetone has been developed. A mathematical model of the process is proposed that takes into account the hydrodynamics of liquid flow and mass transfer in phases for each component. The differential cell model was used to determine the process parameters and calculate the basic dimensions of extractor. In addition, a three-stage process flowsheet with minimum extractant consumption was also presented.
