  • The use of vacuum ultraviolet radiation for investigationof water samples
           with different salt content
    • Authors: S. A. Dolenko; A. M. Kravchenko; A. I. Marinin; V. V. Goncharuk
      Pages: 1 - 6
      Abstract: The paper gives the results of experimental research in photolysis of water samples using vacuum ultraviolet radiation at the wavelength 185 nm. Differences in the kinetics of formation of hydrogen peroxide for different waters found are explained by changes in the structural state of water, which was confirmed in defining sizes of clusters by the method of dynamic light scattering.

  • Biotransformation of the active carbon layer in purifying water of
           2-chlorophenol
    • Authors: S. K. Smolin; O. V. Zabneva; N. A. Klymenko; O. G. Shvydenko
      Pages: 7 - 13
      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.

  • Desalination of glycerol-water solutions by electrodyalysis using the
           organo-inorganic membranes
    • Authors: L. M. Rozhdestvenskaya; Yu. S. Dzyazko; E. O. Kudelko; S. L. Vasilyuk; V. N. Belyakov
      Pages: 26 - 32
      Abstract: The organo–inorganic ion exchange membranes based on heterogeneous membrane materials and inorganic ion exchangers (zirconium hydrophosphate and hydrated zirconium dioxide) have been developed for electrodialysis desalination of glycerol–water solutions. 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: 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: 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: 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: 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.

  • Kinetic and equilibrium studies of fluoride adsorption by a carbonaceous
           material from pyrolysis of waste sludge
    • Authors: V. Dogan; S. Aydin
      Pages: 319 - 326
      Abstract: The efficiency of the adsorption for fluoride by sludge from the treatment of starch industry wastewater was investigated. Batch experiments were conducted in order to determine the parameters that affect the adsorption process. The activation for waste sludge and specific surface area and porosity effects in enhancing the pyrolysis conditions were determined. The adsorption parameters of initial fluoride concentration, pH and adsorbent dosage were investigated with carbonaceous material. As a result of pyrolysis of samples treated with ZnCl2 1196 m2/g, the specific surface area was reached. Correlation coefficient of 0.99 and 12.75 mg/g adsorption capacity and adsorption isotherm model were revealed as convenient. Experimental results show that the adsorption of fluoride waste sludge will be effective in many ways in which the adsorbent is applied.

      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.

      Abstract: The aim of the study was to determine the technological effectiveness of treatment process of model dairy wastewater in anaerobic reactors with active filling (AF), heated with electromagnetic microwave radiation (EMR). Experiments were conducted on a laboratory scale. The AF were produced using micro-pore extrusion technology. The study demonstrated that AF introduction to the technological system and application of EMR significantly improved the effectiveness of organic compounds, phosphorus removal and biogas production. Initial organic loading rate also affected the final results of wastewater treatment.

  • The influence of natural organic matter on trihalomethanes formation
           during the conditioning of drinking water
    • Authors: N. A. Klymenko; E. A. Samsoni-Todorova; L. A. Savchina
      Pages: 353 - 357
      Abstract: The behavior pattern of the content of disinfection by-products in samples from the clean water reservoir of the Dnieper water supply plant as a function of the total organic carbon concentration, ultraviolet absorption at λ = 254 nm, and the specific ultraviolet absorption has been investigated. It was established that with due regard for specific peculiarities of the Dnieper water composition in different year seasons, the total organic carbon concentration was the most expedient for a potential-determining indicator of trihalomethanes formation.

  • Assessment of groundwater quality and its suitability for agricultural
           usage in and around Rangampeta area, Andhra Pradesh, south India
    • Authors: A. Nagaraju; A. Thejaswi; Z. Sharifi
      Pages: 358 - 365
      Abstract: The aim of this study is to assess the groundwater quality of Rangampeta area for irrigation and domestic purposes. The groundwater samples were analyzed for distribution of chemical elements Ca, Mg, Na, K, Si, HCO3, CO3, Cl and SO4. It also includes pH, electrical conductivity, total hardness, non carbonate hardness and total alkalinity. The parameters like sodium absorption ratio, adjusted sodium absorption ratio, sodium percentage, potential salinity, permeability index and residual sodium carbonate were calculated. The dominant hydrochemical facies of groundwater are Ca–Mg–Cl and Na–Cl Water Types. The Gibbs’s diagram plots suggest that the chemical weathering of rock forming minerals is the major driving force controlling water chemistry in this area. The positive chloro-alkaline indices revealed that the groundwater has suffered ion exchange between Na and K of water with Ca and Mg of soil during its flow.

  • Current status of arsenic contamination in drinking water and treatment
           practice in some rural areas of West Bengal, India
    • Authors: J. N. Bhakta; S. Rana; J. Jana; S. K. Bag; S. Lahiri; B. B. Jana; F. Panning; L. Fechter
      Pages: 366 - 373
      Abstract: The aim of the present investigation was to draw the current scenario of arsenic (As) contamination in drinking water of community tube well and drinking water treated by tube wells installed with different adsorbent media-based treatment plants in districts Nadia, Hooghly and North 24-Parganas districts, West Bengal, India. As removal efficiencies of different treatment plants varied from 23 to 71%, which is largely governed by adsorption capacity of adsorbent and influencing environmental factors. Though investigated treatment plants removed substantial amount of As from tube well water, high As concentration in treated drinking water was retained after passing through the treatment plants. This high level of As concentration in tube well water and retention of high As concentration in treated drinking water were severe for the consumers which therefore, indicating the improvement of removal efficiency of treatment plant by meticulously considering favorable influencing factors or/and application of other high capacity treatment alternatives to adsorb the excess As retained in drinking water and regular monitoring of As concentration in the treated drinking water are indispensable.
