  • Electrokinetic intensification of dehydration of complex disperse systems
    • Authors: L. L. Lysenko; N. A. Mishchuk; T. A. Nesmeyanova
      Pages: 249 - 254
      Abstract: Abstract The paper has investigated the efficiency of dehydration of two-component dispersion system in its mechanical treatment and additional effect of the electric field. It is shown that at the presence of a gel-like organic component substantially making difficult the process of removing liquid, the degree of dehydration noticeably decreases. For achieving acceptable values of finite moisture in such systems it is necessary to create conditions ensuring electroosmotic transfer of liquid.

  • Optimizing linear alkyl benzene sulfonate removal using Fenton oxidation
           process in Taguchi Method
    • Authors: H. Khorsandi; A. Mohammadi; F. Kariminejad; M. Haghighi; S. Karimzadeh; J. Khorsandi; A. A. Aghapour
      Pages: 266 - 272
      Abstract: Abstract Linear alkyl benzene sulfonate (LAS), which is the most common used anionic surfactant in detergents manufacturing, can discharge onto water resources through wastewater and causes change in taste and odor, disruption in water treatment processes, aquatics death, and oxygen transfer limitation. Accordingly, this article investigates to optimize LAS removal using Fenton oxidation process in Taguchi Method for the first time. LAS removal using Fenton oxidation was perused experimentally in a lab-scale reactor. In order to save relevant costs, 25 runs were qualified to specify the optimum conditions of Fenton oxidation using Taguchi method by Minitab 16 software. Sampling and testing procedures were executed based on the standard methods for the examination of water and wastewater. The optimum conditions included 900 mg/L hydrogen peroxide, 170 mg/L ferrous ion, pH of 4 and the reaction time of 20 min. Fenton oxidation, as a second order reaction with the rate coefficient of 0.0152 L/mg⋅min, provided 86.5% efficiency for LAS removal in the optimum conditions. Despite Fenton oxidation appeared as a high efficiency process in LAS removal, low removal efficiency of chemical oxygen demand corresponding with LAS affirmed its partial degradation.

  • Rapid ultrasensitive chemometrics-fluorescence methodology to quantify
           fluoroquinolones antibiotics residues in surface water
    • Authors: D. González-Gómez; F. Cañada-Cañada; A. D. Campiglia; A. Espinosa-Mansilla; A. Muñoz de la Peña; Jin Su Jeong
      Pages: 280 - 286
      Abstract: Abstract A sensitive method for the determination of fluoroquinolones in surface waters at trace concentration level is presented. The proposed two-step methodology consists in a solid-phase extraction using C-18 membranes followed measurement of the emission molecular fluorescence spectra over extracted membrane without elution of the analytes. Membrane background signal was removed by the used of chemometrics calculations, in addition chemometrics was as well used for the direct and simultaneous determination of the studied compounds. The method was optimized for the analysis of three fluoroquinolones: enoxacin (ENO), norfloxacin (NOR) and ofloxacin (OFLO). The fluorescence of these compounds increase drastically when they are in the membrane, thus with this method low concentrations are possible to be determined, as the concentration in which these compounds appear in surface water. Limits of detection at the ng•L–1 level were estimated for ENO, NOR and OFLO.

  • Biosorption of procaine on biologically active carbon
    • Authors: E. A. Korzh; N. A. Klymenko; S. K. Smolin; L. R. Reshetnyak
      Pages: 287 - 293
      Abstract: Abstract The article has studied the dynamics of biosorption purification of water of procaine adapted by biomass of active sludge immobilized on activated carbon. The greatest constant of the rate of biodestruction of procaine (0.151 h–1) suspended by adapted biomass is observed at the concentration of the matter 100 mg/dm3. At biosorption removal of procaine on activated carbon under conditions of stirring the constants of the rates of biodestruction increase two–five times compared with suspended biomass. The adapted biofilm noticeably extend the service life of carbon compared with the spontaneously emerging biofilm at the sake of higher destruction activity.

  • Kinetics of adsorption of pharmaceutical substances from aqueous solutions
           on activated carbons
    • Authors: E. A. Korzh; S. K. Smolin; N. A. Klymenko
      Pages: 187 - 193
      Abstract: Abstract The article has investigated regularities of adsorption of sulfanilamide, sulfathiazole, procaine, levamisole and caffeine on activated carbons of various porous structure. The adsorption rate of substances diminishes in the series sulfanilamide > caffeine > procaine > sulfathiazole > levamisole and decreases with an increase of the fraction of micropores in the structure of sorbents. It was found that at the degree of using the adsorption capacity of the sorbent of up to γ = 0.5–0.6 the kinetics of adsorption satisfactorily is described by means of an external diffusion model. The use of 50% of sorption capacity of activated carbon is achieved over ~ 10% time necessary for establishing adsorption equilibrium.

      Pages: 194 - 199
      Abstract: Abstract Modification of a homogenous anion–exchange MA-100 membrane by chlorosulfonic acid is accompanied by grafting of negatively charged–SO 3 – groups and a substantial increase of hydrophilicity. The method of differential scanning calorimetry indicated that the mass fraction of free and bound water increases nearly twice. The porous structure of the modified membrane becomes more developed at the expense of an increase of the volume of micropores. The membrane acquires resistance to poisoning by large organic anions.

  • Kinetics of photodegradation of alizarin green in an acoustic fluidized
           bed using TiO 2 catalyst
    • Authors: C. Si; J. Zhou; Y. Sun; G. Liu; H. Gao
      Pages: 207 - 212
      Abstract: Abstract The kinetics of photodegradation of alizarin green (AG) in an acoustic fluidized bed was investigated using Degussa P25 catalyst and N-doped TiO2 catalyst, respectively. The effects of initial concentration of AG, catalyst amount, initial pH value and liquid flow rate on the photodegradation rates were the main goal of present study. The degradation rate increased with increasing amount of photocatalyst, pH value and liquid flow rate, reached a maximum and then decreased. The degradation rate decreased with increasing initial concentration. According to the Langmuir–Hinshelwood model, the disappearance of the AG followed pseudo-first-order kinetics. Experimental results showed that AG can be degraded effectively by Degussa P25 catalyst and N-doped TiO2 catalyst in an acoustic fluidized bed reactor. N-doped TiO2 catalyst has high and significant photocatalytic activity and in comparison with Degussa P25 catalyst was photocatalyst.

  • Liquid extraction treatment of wastewaters at paint and varnish production
           facilities using the spray column
    • Authors: A. A. Gasanov
      Pages: 224 - 231
      Abstract: Abstract The technology of liquid extraction treatment of wastewaters of the paint and varnish production facility using a three-stage spray extractor has been developed for the removal of butylglycol, phenyl isopropanol, acetic acid, and acetylacetone using isopropyl ether as an extractant. A mathematical model of extraction is presented that takes into account the hydrodynamics of countercurrent liquid flows, the mass transfer and mass exchange of liquid phases for each component. The differential cell model is applied to determine optimal parameters of the process, calculate basic dimensions of the spray extractor, and propose a three-stage process flowsheet with the minimum consumption of extractant at the ratio 1: 15 in relation to wastewater.

  • Bioaugmentation of a sequencing batch reactor with Archaea for the
           treatment of reject water
    • Authors: A. Szaja; G. Lagód; J. Drewnowski; F. Sabba
      Pages: 238 - 243
      Abstract: Abstract In this study, the bioaugmentation of a sequencing batch reactor (SBR) for the treatment of reject water from wastewater treatment plant was evaluated. For the bioaugmentation step a product containing an enrichment of microorganisms from the Archaea domain was used to enhance the performance of the reactor for treating reject water. The experiment was carried out in two parallel lab-scale sequencing batch reactors. The first one (SBR A) was bioaugmented with a suspension of microorganisms from the Archaea domain, while the second reactor (SBR B) was not bioaugmented. The results here presented show that the SBR technology could sustain efficient NH 4 + –N and chemical oxyden demand removal rates and can be applied for the treatment of reject water. Moreover, the addition of microorganisms belonging to the Archaea domain improved the SBR overall operation, especially when the loading in the influent was increased. Administering Archaea to the reactor had also a positive effect on ammonia oxidation as well as on the nitrite removal.

  • Chemical assessment of Sambhar Soda Lake, a Ramsar site in India
    • Authors: M. N. Cherekar; A. P. Pathak
      Pages: 244 - 247
      Abstract: Abstract The Sambhar Soda Lake situated in Rajasthan, is the largest inland salt lake. The chemical assessment of this lake water is studied with respect to its abiotic characters. Monsoon and winter water sample analyses revealed that the lake water is hypersaline and highly alkaline in nature. The average maximum pH is 9.5 and salinity 30%, which is one of the unique features of this lake. As compared to monsoon water sample the winter sample contains remarkable concentration of various ions like sodium (9930 mg/L), chloride (7356 mg/L), bicarbonates (6080 mg/L), sulfate (9152 mg/L). Various metals were recorded from this sample analysis. The considerable amount of lead (1359 μg/L), cadmium (1416 μg/L), copper (2099 μg/L), and cobalt (2453 μg/L) metals were found from winter 2010 sample. As compare of to other saline lake and sea water the Sambhar Lake water chemistry is different, and require continuous monitoring.
