Phylogenetic diversity of aqueous microorganisms separated after the advanced tertiary of tap water
Journal of Water Chemistry and Technology - Tập 36 - Trang 184-189 - 2014
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 ide...... hiện toàn bộ
Determination of phenol in the Bangsai River water of Bangladesh by gas chromatography-mass spectrometry
Journal of Water Chemistry and Technology - Tập 33 - Trang 91-96 - 2011
A simple, sensitive and rapid gas chromatography-mass spectrometry (GC-MS) method is proposed for the analysis of some environmentally important highly toxic phenols in water. The concentration level of phenol was determined in water at the sampling stations of Savar, Dhaka Export Processing Zone (DEPZ) and Bank Colony of the Bangsai River, Bangladesh. Water samples were collected from different d...... hiện toàn bộ
Difficulties in the anammox process start-up in sequencing batch reactor at low temperature
Journal of Water Chemistry and Technology - Tập 39 - Trang 237-244 - 2017
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 prese...... hiện toàn bộ
Photocatalysis with the Use of ZnO Nanostructures as a Method for the Purification of Aquatic Environments from Dyes
Journal of Water Chemistry and Technology - Tập 43 - Trang 281-288 - 2021
The papers devoted to the purification of aquatic environments from industrial contaminants with the use of ZnO based nanosized photocatalysts in the period of 2018–2020 are analyzed. The data published in these papers have made it possible to determine the dye (V) destruction rate used further as a photocatalytic activity criterion. As shown by the comparative analysis of the photocatalytic activ...... hiện toàn bộ
Biosorption removal of nitrophenols by activated carbon
Journal of Water Chemistry and Technology - Tập 36 - Trang 97-101 - 2014
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 ...... hiện toàn bộ
Use of ultrasound in water treatment
Journal of Water Chemistry and Technology - Tập 30 - Trang 137-150 - 2008
Investigations dealing with the treatment of aqueous systems by physical methods show that ultrasound is an effective reagentless and highly ecological method of water purification of organic pollutants and microorganisms. Its use is particularly effective in combined methods of treatment: ultrasound + ultraviolet irradiation; ultrasound + ultraviolet + ozonization; ultrasound + hydrogen peroxide;...... hiện toàn bộ
Removal and Photodegradation of Metolachlor Herbicide Using Polyelectrolyte Multilayer Membranes
Journal of Water Chemistry and Technology - Tập 45 - Trang 574-585 - 2023
The study illustrates the use of polyelectrolyte multilayer (PEM) membranes prepared with weak/strong polyelectrolyte combination of poly(ethyleneimine)/chondroitin sulfate A (PEI/CS) for the removal of metolachlor (MTR) from water samples. The proposed PEM membranes were characterized by chemical, physical, thermal, and morphological properties. The removal of MTR herbicide by PEI/CS multilayer d...... hiện toàn bộ
Utilization of toxic slimes produced during the chemical regeneration of complexes of heavy metals after the baromembrane water purification
Journal of Water Chemistry and Technology - Tập 31 - Trang 316-323 - 2009
A method has been developed for the utilization of salts of heavy metals generated due to chemical regeneration of complexes of concentrates after the baromembrane treatment of polluted waters. This method implies the immobilization in glass-ceramic matrices. The optimal composition of matrices was determined and their physico-mechanical properties were investigated. The matrices featuring good pe...... hiện toàn bộ

Decolorization and MIneralization of Methylene Blue in Aqueous Solutions by Persulfate/Fe2+ Process
Journal of Water Chemistry and Technology - Tập 42 - Trang 244-251 - 2020
Today, the treatment of dye wastewater discharged by various industries, such as textiles, has attracted the attention of many researchers due to the non-biodegradability nature of dye contaminants. Methylene blue is one of numerous dyes existing in this wastewater that causes a variety of human health problems. Because of the low efficiency of biological treatment processes in the removal of this...... hiện toàn bộ
