Adsorptive removal of dyes from synthetic and real textile wastewater using magnetic iron oxide nanoparticles: Thermodynamic and mechanistic insights

20-Aug-2015 | Nashaat N. Nassar, Nedal N. Marei, Gerardo Vitale, Laith A. Arar, The Canadian Journal of Chemical Engineering, 2015

Abstract Magnetic iron‐oxide nanoparticles exhibit high efficiency in wastewater treatment for many important reasons, including that they can remove contaminants from wastewater rapidly owing to their high external surface area/unit mass and interstice reactivity. Additionally, this type of ...

IJERPH, Vol. 12, Pages 9692-9713: Prevalence of Antimicrobial Resistant and Virulent Salmonella spp. in Treated Effluent and Receiving Aquatic Milieu of Wastewater Treatment Plants in Durban, South Africa

18-Aug-2015 | Odjadjare, Ejovwokoghene C.; Olaniran, Ademola O., International Journal of Environmental Research and Public Health, 2015

In this study, we evaluated the impact of treated wastewater effluent from two wastewater treatment plants on the physicochemical parameters and Salmonella spp. load of receiving rivers. Presumptive Salmonella spp. were obtained at all sampled points including the discharge points, with counts ...

Engineering Design of Outer‐Selective Tri‐bore Hollow Fiber Membranes for Forward Osmosis and Oil‐Water Separation

14-Aug-2015 | Xue Li, Wan Lin Ang, Yingda Liu, Tai‐Shung Chung, AIChE Journal, 2015

Abstract Outer‐selective thin‐film composite (TFC) hollow fiber membranes offer advantages like less fiber blockage in the feed stream and high packing density for industrial applications. However, outer‐selective TFC hollow fiber membranes are rarely commercially available due to the lack of ...

IJERPH, Vol. 12, Pages 9542-9561: Solar-Enhanced Advanced Oxidation Processes for Water Treatment: Simultaneous Removal of Pathogens and Chemical Pollutants

14-Aug-2015 | Tsydenova, Oyuna ; Batoev, Valeriy ; Batoeva, Agniya, International Journal of Environmental Research and Public Health, 2015

The review explores the feasibility of simultaneous removal of pathogens and chemical pollutants by solar-enhanced advanced oxidation processes (AOPs). The AOPs are based on in-situ generation of reactive oxygen species (ROS), most notably hydroxyl radicals •OH, that are capable of destroying ...

Life-Cycle Energy Use and Greenhouse Gas Emissions of a Building-Scale Wastewater Treatment and Nonpotable Reuse System

12-Aug-2015 | Thomas P. Hendrickson; Mi T. Nguyen; Marsha Sukardi; Alexandre Miot; Arpad Horvath; Kara L. Nelson, Environmental Science & Technology, 2015

Treatment and water reuse in decentralized systems is envisioned to play a greater role in our future urban water infrastructure due to growing populations and uncertainty in quality and quantity of traditional water resources. In this study, we utilized life-cycle assessment (LCA) to analyze the ...

Emulsifying Properties of Sericin Obtained from Hot Water Degumming Process

11-Aug-2015 | L.C.B. Züge, V.R. Silva, F. Hamerski, M. Ribani, M.L. Gimenes, A.P. Scheer, Journal of Food Process Engineering, 2015

Abstract Sericin is a protein present in the silkworm cocoon of Bombyx mori. Although usually discarded during the silk degumming process, which causes environmental impact and high costs of wastewater treatment, this protein possesses properties that are particularly useful to the food ...

Anaerobic granular reactors for the treatment of dairy wastewater: A review

11-Aug-2015 | Dogan Karadag, Oguz Emre Koroglu, Bestami Ozkaya, Mehmet Cakmakci, Sonia Heaven, Charles Banks, Alba Serna‐Maza, International Journal of Dairy Technology, 2015

Considerable research has been conducted on the treatment of dairy wastewater by anaerobic granular reactors. Upflow anaerobic sludge blanket (UASB) reactors, anaerobic sequencing batch reactors (ASBR) and static granular bed reactors (SGBR) are the conventional granular reactor types most ...

Pyrolysis Characteristics and Char Reactivity of Oedogonium sp. and Loy Yang Coal

10-Aug-2015 | Youjian Zhu; Chi Wai Kwong; Philip J. van Eyk; Rocky de Nys; Dingbiao Wang; Peter J. Ashman, Energy & Fuels, 2015

The proposition of combining the application of algae in wastewater treatment, CO2 fixation, and energy production maximizes the opportunity of algal bioremediation. In this paper, the freshwater macroalga Oedogonium, a key target species for the bioremediation of waste waters, was investigated ...

Development of Prediction Models for the Reactivity of Organic Compounds with Ozone in Aqueous Solution by Quantum Chemical Calculations: The Role of Delocalized and Localized Molecular Orbitals

07-Aug-2015 | Minju Lee; Saskia G. Zimmermann-Steffens; J. Samuel Arey; Kathrin Fenner; Urs von Gunten, Environmental Science & Technology, 2015

Second-order rate constants (kO3) for the reaction of ozone with micropollutants are essential parameters for the assessment of micropollutant elimination efficiency during ozonation in water and wastewater treatment. Prediction models for kO3 were developed for aromatic compounds, olefins, and ...
