  • Features of water defluorination by galvano- and electrocoagulation
    • Abstract: Abstract The paper has investigated regularities of water defluorination by methods of galvano- and electrocoagulation. It has been shown that electrocoagulation ensures more effective defluorination of water than galvanocoagulation. It has been proposed to use the methods in question for removal of fluorides from concentrates being formed in defluorination of water by reverse osmosis.

  • Determination of bromate ions in waters by diffusion reflection
           spectroscopy
    • Abstract: Abstract The photometric method of determining trace amounts of bromates in drinking water has been developed. The method has been based on measuring diffusion reflection of tinted concentrated of the ionic associate of basic fuchsine with anionic surfactant; detection limit—0.5 μg/dm3. The analysis is not hampered by components usually interfering in determination of bromates by other methods such as chloride, chlorate, iodate, chloramines, etc. The proposed method makes it possible to control the content of bromates in water at the level and below the maximum accessible concentration.

  • Synthesis and application of an environmentally friendly antiscalant in
           industrial cooling systems
    • Abstract: Abstract A novel double-hydrophilic block copolymer, acrylic acid-allylpolyethoxy carboxylate, was specially designed and synthesized from allyloxy polyethoxy ether. The study shows that acrylic acid-allylpolyethoxy carboxylate has significant ability to inhibit the precipitation of calcium carbonate and excellent dispersing capability to stabilize iron (III) in industrial cooling systems. X-ray diffraction shows that there is a number of vaterite crystals in the presence of the phosphorous free and non-nitrogen copolymer; the change of crystal forms was also confirmed by fourier-transform infrared spectra, scanning electron microscopy and transmission electron microscopy.

  • Treatment of sewage and industrial wastewater effluents by the
           cyanobacteria Nostoc
           muscorum
    and Anabaena
           subcylinderica
    • Abstract: Abstract The potential of two cyanobacteria, Nostoc muscorum and Anabaena subcylindrica to treat sewage and industrial wastewater effluents was investigated. Two different sites were selected for this study which are located at the drains of sewage plant, a salt and soda production company at Kafr El-Zayat city. All samples were taken from the sewage and/or industrial effluents before treatment. Treatment of the sewage and industrial wastewater effluents by using cyanobacteria (N. muscorum, A. subcylindrica and mixed culture of both) revealed that the pH value of the biologically treated wastewater increased, the electrical conductivity was recovered in a range between (4.7–23.9%) and the total dissolved solids were reduced by (4.4–23.3%). The reduction of turbidity level was in a range between (40–96.4%). The removal efficiency of organic matter (COD, PV) was in a range between (20–57.1%) and (25.7–66.7%), respectively. Phosphorus reduction, nitrate treatment and ammonia elimination efficiencies by cyanobacterial system were (20.8–95%), (19.6–80%) and (20.9–96%), respectively. With respect to the treatment efficiency of wastewater by using single or mixed cultures of cyanobacteria, it was observed that the single cultures in most cases was better than the mixed cultures and this may be due to the competition between mixed cultures for nutrients. However, it could be concluded from the presented data that the treatment of wastewater by cyanobacteria is a fruitful method to produce an effluent of high quality to be used for irrigation.

  • Phylogenetic diversity of aqueous microorganisms separated after the
           advanced tertiary of tap water
    • Abstract: Abstract The species composition of bacterial community of the drinking tap water and water samples taken at different purification stages of the water conditioning plant at an enterprise producing special drinks has been analyzed. This study involves the analysis of 16S rRNA gene sequences and the use of molecular biology methods based on the phylogenetic analysis. The following bacterial species were identified: Bacillus nanhaiensis, Brevibacterium frigoritolerans, and Lysinibacillus fusiformis. All the studied strains belong to phylum Firmicutes, class Bacilli representing Gram-positive microorganisms that are not pathogenic to human. The presence of the bacteria investigated in different habitats such as the drinking chlorinated water, in the presence of stress factors (arid climate, high or low temperatures, depleted soil, and the occurrence of disinfectants) indicates their ability to easily adapt to new living conditions expanding their habitat.

  • High-gradient ferromagnetic matrices for purification of wastewaters by
           the method of magnitoelectrolysis
    • Abstract: Abstract The paper has investigated the efficiency of high-gradient ferromagnetic matrices of a magnetic filter obtained by the method of magnetoelectrolysis at different parameters of the process using a magnetically controlled biosorbent based on the yeast S. cerevisiae and nanomagnetite. The paper has studied the morphology of matrices at different parameters of electric precipitation such as the value of the external magnetic field and magnetization conditions of the matrix base. We have measured quantitative indices of the operation of every type of matrices: maximum efficiency of extraction of the magnetically controlled biosorbent of ions of metals from wastewaters and the optimal time of the operation of manufactured matrices.

  • Adaptation of water quality index (       class="a-plus-plus">WQI) for groundwater quality
           assessment near the landfill site
    • Abstract: Abstract In this paper the level of groundwater contamination near the municipal landfill site is examined. A modified WQI was used to determine the change in groundwater quality. A total of 127 groundwater samples were analyzed for pH, EC, PAH, TOC, Pb, Cu, Cd, Cr, Zn, Hg. The mean value of the WQI for groundwater outflow from the landfill was 8.01, which means a very high landfill impact. Most contaminated water was in piezometers P2 and P3 located to the east from the landfill border with the WQI value of 9.12 and 10.48, respectively. The WQI in the P1 piezometer, situated to the north-west of the landfill reached a value of 4.41. The highest WQI value in analyzed water was recorded in summer (mean: 10.59); the lowest in March (mean: 4.57). The trend line equation point to a stabilizing water quality in P1 and P2 and a growing trend in P3.

  • Impact of polyethyleneimine on utrafiltration extraction of Cr(VI) from
           contaminated waters
    • Abstract: Abstract The paper has investigated the possibility of using polyethylenimine with different molecular weight for purification of polluted water of Cr(VI) by the method of ultrafiltration. The paper has determined the impact of the pH of the medium, concentration, and molecular weight of polyethylenimine on the degree of removing Cr(VI) from waters containing chromium. Efficiency of water purification of Cr(VI) virtually does not depend on the molecular weight of polyethylenimine used.

  • The efficiency of municipal wastewater treatment with the reconstructed
           activated sludge method
    • Abstract: Abstract Centralized wastewater treatment policy is a common challenge in Hungary. With the recent technology improvement of the Debrecen Wastewater Treatment Plant, the original activated sludge function system’s maximum load is doubled, making it able to treat the effluents of 7 settlements total. The introduced new technical constructions however required strict attention to be successfully integrated into the existing system. Retrofitting the overall processes caused disturbances affecting certain parameters in the biological treatment, thus modifying water quality of the effluent. Our experiments had aimed to control the performance of the plant after the reconstruction during test phase for more than a year period. It has been found that a slight increase of removal efficiency was achieved in the observed parameters of COD, BOD5, TP, SS, while TN remained in a moderate degree of enhancement. Retention effectiveness has begun to escalate significantly after a year of operation.

  • Removal of chloromethanes from water by the method of vapor-phase
           extraction
    • Abstract: Abstract The paper has studied the removal of chloromethanes from aqueous media by the method of vapor-phase extraction. Acetonitrile, ethoxyethane, and hexane were used as extractants. Using the removal from aqueous solutions of methylene chloride, chloroform, and carbon tetrachloromethane as an example it was found that vapor-phase extraction was more effective than gas one. The flow-chart for the removal of chloromethanes from polluted waters by vapor-phase extraction in the flowing mode of the closed cycle for using an extractant has been proposed.

  • Adsorption of copper ions by carbon adsorbents modified by phosphoric acid
           at different temperatures
    • Abstract: Abstract The article has investigated adsorption of copper ions by activated carbons from coconuts at different temperatures (400–900°C). Adsorption of copper ions was studied at different values of the pH and initial concentrations. It has been shown that an increase of temperature of modifying carbon results in a growth of the degree of copper extraction. It has also been detected that the presence of albumin in the solution does no affect the degree of copper extraction.

  • Isotope osmosis—Osmotic transfer of water isotopologues through the
           polymer membrane in the course of direct osmosis
    • Abstract: Abstract The article has investigated osmosis transfer through a polymer semi-permeable membrane of water having a different concentration of deuterium in the course of direct osmosis. For the first time osmosis transfer of water isotopologues—deuterium and oxygen 18—through the polymer semi-permeable membrane separating light and heavy water has been detected. The article presents results indicating that isotope osmosis suppresses osmotic stream existing owing to different concentration of chemical components dissolved in light and heavy waters.

  • Photolysis of waters with the different isotope composition
    • Abstract: Abstract The article has investigated features of changes of physicochemical properties of water with the different isotope composition after its photolysis under the effect of radiation by a quartz argon-mercury low-pressure lamp (DRB-20) at the wavelength 185 nm. Results of experiments on photolysis of light, high-resistance, and heavy water are an evidence that light water in great measure is subjected to photocatalytic decomposition at radiation compared with high-resistance and heavy waters, which is determined, in the first place, by less strength of its hydrogen bond.

  • Reactive Red 120 dye removal from aqueous solution by adsorption on
           nano-alumina
    • Abstract: Abstract The adsorption of Reactive Red 120 dye from aqueous solutions by using nano-alumina has been investigated. The batch adsorption studies were carried out to determine the impact of pH, contact time, concentration of dye, and the adsorbent dose on adsorption process. The maximum adsorption efficiency was observed at pH 3. However with an increase of the adsorbent dose, the dye removal efficiency increased, while the amount of dye adsorbed per unit mass (mg/g) decreased. A pseudo-second-order model best described the adsorption kinetics of the specified dye onto nano-alumina. In this case the Langmuir isotherm model appeared to be most suitable. Findings of the present study reveal that nano-alumina can be an effective adsorbent for the removal of Reactive Red 120 from aqueous solutions.

  • Water purification of sulfates by liming when adding reagents containing
           aluminum
    • Abstract: Abstract The article has investigated the processes of water purification of sulfates when treating with lime, sodium aluminate or aluminum hydroxide. It has been shown that the efficiency of removing sulfates depends on the type and consumption of reagents containing aluminum and the method of pretreating aluminum hydroxide. The paper has determined the effect of after treatment by carbon dioxide or magnesite on the efficiency of water purification of sulfates, the degree of its softening, and residual alkalinity.

  • Biosorption removal of nitrophenols by activated carbon
    • Abstract: Abstract The article has investigated the efficiency of biofiltration of solutions 2,4-dinitrophenol and 2-nitriphenol through activated carbon of the grade KAU—usual and modified by iron oxide. It has been shown that both sorbents are characterized by a high selective adsorption for substances being investigated. The impact of modification of carbon by iron oxides when removing nitrophenols is manifested in an increase of active life of biofilter operation and activization of the biofilm development.
