Spent green tea leaves for decolourisation of raw textile industry wastewater
11-05-2013 | Chih‐Huang Weng, Yao‐Tung Lin, Yen‐Jung Chen, Yogesh Chandra Sharma, Coloration Technology, 2013
True colour measurements of wastewater samples, in terms of American Dye Manufacturers' Institute values, were used to evaluate the effectiveness of decolourisation of textile wastewater using spent green tea leaf powder waste. Raw wastewater samples with a true colour of 868 ADMI were used ...
Biotoxicity Evaluation of Coking Wastewater Treated with Different Technologies Using Japanese Medaka (Oryzias latipes)
08-05-2013 | Xiaobiao Zhu; Lujun Chen; Rui Liu; Cong Liu; Zhengdao Pan, Journal of Environmental Monitoring, 2013
The potential biotoxicity to environment should be addressed during wastewater treatment. In this study, biotoxicity for coking wastewater effluent from MBR, Fenton, electro-Fenton and coagulation treatment processes was evaluated using embryos and larva of Japanese medaka (Oryzias latipes). ...
Detecting Human Bacterial Pathogens in Wastewater Treatment Plants by a High-Throughput Shotgun Sequencing Technique
02-05-2013 | Lin Cai; Tong Zhang, Environmental Science & Technology, 2013
Human pathogens are one of the major threats to global public health. Wastewater treatment plants (WWTPs) serve as city guts to receive and digest various human pathogens. Several techniques have been developed to detect human pathogens in WWTPs and to assess potential environmental risks. In ...
Inhibitory effects of sulfide on nitrifying biomass in the anaerobic ‐anoxic‐aerobic wastewater treatment process
19-04-2013 | Zhen Zhou, Can Xing, Ying An, Dalong Hu, Weimin Qiao, Luochun Wang, Journal of Chemical Technology & Biotechnology, 2013
Abstract Background Long pipeline transportation of wastewater usually generates high concentration of sulfide; however, information on nitrification inhibition by sulfide in the anaerobic‐anoxic‐aerobic (AAO) process is still scarce. This study focused on how sulfide could inhibit ...
Nitrogen removal from temperate anaerobic‐aerobic two stage biological systems: Impact of reactor type and wastewater strength
17-04-2013 | Anna.L. Eusebi, Nacho. Martin‐Garcia, Ewan.J. McAdam, Bruce. Jefferson, John.N. Lester, Elise. Cartmell, Journal of Chemical Technology & Biotechnology, 2013
Abstract Background There is a need to examine the impact of anaerobic reactor type and wastewater strength on anaerobic‐aerobic two stage biological systems for temperate wastewater treatment An expanded granular sludge blanket reactor and an anaerobic membrane bioreactor for crude ...
Ultrathin Calcium Silicate Hydrate Nanosheets with Large Specific Surface Areas: Synthesis, Crystallization, Layered Self‐Assembly and Applications as Excellent Adsorbents for Drug, Protein, and Metal Ions
15-04-2013 | Jin Wu, Ying‐Jie Zhu, Feng Chen, Small, 2013
Abstract A simple and low‐cost solution synthesis is reported for low‐crystalline 1.4 nm tobermorite‐like calcium silicate hydrate (CSH) ultrathin nanosheets with a thickness of ∼2.8 nm and with a large specific surface area (SSA), via a reaction‐rate‐controlled precipitation process. The ...
Development of sensitive determination method for benzotriazole uv stabilizers in enviromental water samples with stir bar sorption extraction and liquid desorption prior to ultra‐high performance liquid chromatography with tandem mass spectrometry
11-04-2013 | Sarah Montesdeoca‐Esponda, Adrián del Toro‐Moreno, Zoraida Sosa‐Ferrera, José Juan Santana‐Rodríguez, Journal of Separation Science, 2013
Benzotriazole ultra‐violet stabilisers are emerging compounds used in personal care products and can enter surface water after passing through wastewater treatment plants without be removed. Because these analytes are strongly hydrophobic, there is an environmental risk of accumulation in ...
Mass Balance of Perfluoroalkyl Acids in the Baltic Sea
11-04-2013 | Marko Filipovic; Urs Berger; Michael S. McLachlan, Environmental Science & Technology, 2013
A mass balance was assembled for perfluorohexanoic acid (PFHxA), perfluorooctanoic acid (PFOA), perfluorodecanoic acid (PFDA), and perfluorooctanesulfonic acid (PFOS) in the Baltic Sea. Inputs (from riverine discharge, atmospheric deposition, coastal wastewater discharges, and the North Sea) ...
Long-Term Performance of Liter-Scale Microbial Fuel Cells Treating Primary Effluent Installed in a Municipal Wastewater Treatment Facility
09-04-2013 | Fei Zhang; Zheng Ge; Julien Grimaud; Jim Hurst; Zhen He, Environmental Science & Technology, 2013
Two 4 L tubular microbial fuel cells (MFCs) were installed in a municipal wastewater treatment facility and operated for more than 400 days on primary effluents. Both MFCs removed 65–70% chemical oxygen demand (COD) at a hydraulic retention time (HRT) of 11 h and reduced about 50% suspended ...
Photocatalytic degradation of methylene blue on magnetically separable MgFe2O4 under visible light irradiation
08-04-2013 | Materials Chemistry and Physics, 2013
15 May 2013 Publication year: 2013Source:Materials Chemistry and Physics, Volume 139, Issues 2–3 A magnetically separable single-phase MgFe2O4 photocatalyst with a spinel crystal structure was synthesized by using the solid-state reaction method. The formation of spinel structure ...
