Floating photovoltaic arrays to power the mining industry: A case study for the McFaulds lake (Ring of Fire)

20-Nov-2015 | Kim Trapani, Dean L. Millar, Environmental Progress, 2015

The article looks at the integration of crystalline and thin film (a‐Si) floating photovoltaic (PV) arrays for electricity generation in remote mine sites. Floating PV arrays rather than regular ground mounted PV arrays are considered more suitable for the site because it decreases the ...


Environment friendly synthesis of magnetite–graphene composite for adsorption of toxic chromium (VI) ions from drinking water

19-Nov-2015 | Dilip K.L. Harijan, Vimlesh Chandra, Environmental Progress, 2015

Magnetite graphene composite (MGC) was synthesized via environment friendly route via thermal reduction of graphene oxide to graphene in alkali solution at 90°C and in the absence of toxic hydrazine hydrate. X‐ray diffraction pattern of MGC shows formation of magnetite phase with crystallite ...


Sustainability, Vol. 7, Pages 15302-15318: Adsorptive Removal of Reactive Black 5 from Wastewater Using Bentonite Clay: Isotherms, Kinetics and Thermodynamics

18-Nov-2015 | Amin, Muhammad Tahir; Alazba, Abdulrahman Ali; Shafiq, Muhammad, Sustainability, 2015

The studies of the kinetics and isotherms adsorption of the Reactive Black 5 (RB5) onto bentonite clay were explored in a batch study in a laboratory. The maximum RB5 adsorption conditions of bentonite clay were optimized such as shaking speed (100 rpm), temperature (323 K), pH (10), contact ...


Effects of pH and dissolved oxygen on the photodegradation of 17[small alpha]-ethynylestradiol in dissolved humic acid solution

18-Nov-2015 | Dong Ren; Bin Huang; Tingting Bi; Dan Xiong; Xuejun Pan, Journal of Environmental Monitoring, 2015

To probe the mechanisms responsible for pH and dissolved oxygen (DO) affecting the photodegradation of EE2 in dissolved humic acid (HA) solution, EE2 aqueous solutions with pH ranging from 3.0 to 11.0 and different DO conditions were irradiated by a 300 W mercury lamp equipped with 290 nm light ...


Monohydroxylated Polybrominated Diphenyl Ethers (OH-PBDEs) and Dihydroxylated Polybrominated Biphenyls (Di-OH-PBBs): Novel Photoproducts of 2,6-Dibromophenol

16-Nov-2015 | Hongxia Zhao; Jingqiu Jiang; Yanli Wang; Hans-Joachim Lehmler; Garry R. Buettner; Xie Quan; Jingwen Chen, Environmental Science & Technology, 2015

Hydroxylated polybromodiphenyl ethers (OH-PBDEs) are emerging aquatic pollutants, but their origins in the environment are not fully understood. There is evidence that OH-PBDEs are formed from bromophenols, but the underlying transformation processes remain unknown. Here, we investigate if the ...


IJERPH, Vol. 12, Pages 14420-14428: Reduction of Acid-Fast and Non-Acid-Fast Bacteria by Point of Use Coagulation-Flocculation-Disinfection

13-Nov-2015 | Casanova, Lisa M.; Sobsey, Mark D., International Journal of Environmental Research and Public Health, 2015

Point of use (POU) household water treatment is increasingly being adopted as a solution for access to safe water. Non-tuberculous Mycobacteria (NTM) are found in water, but there is little research on whether NTM survive POU treatment. Mycobacteria may be removed by multi-barrier treatment ...


Sustainability, Vol. 7, Pages 15057-15072: Removal of Dimethyl Sulfide from Aqueous Solution Using Cost-Effective Modified Chicken Manure Biochar Produced from Slow Pyrolysis

13-Nov-2015 | Nguyen, Minh-Viet ; Lee, Byeong-Kyu, Sustainability, 2015

This study investigated the characteristics of using a cost-effective, amine-modified biochar (BC) derived from chicken manure for removing dimethyl sulfide (DMS) from an aqueous solution. The amine-modified BC showed much higher adsorption of DMS compared to commercial activated carbons under ...


Role of Reverse Divalent Cation Diffusion in Forward Osmosis Biofouling

09-Nov-2015 | Ming Xie; Edo Bar-Zeev; Sara M. Hashmi; Long D. Nghiem; Menachem Elimelech, Environmental Science & Technology, 2015

We investigated the role of reverse divalent cation diffusion in forward osmosis (FO) biofouling. FO biofouling by Pseudomonas aeruginosa was simulated using pristine and chlorine-treated thin-film composite polyamide membranes with either MgCl2 or CaCl2 draw solution. We related FO biofouling ...


Microfluidic Flow through Polyaniline Supported by Lamellar-Structured Graphene for Mass-Transfer-Enhanced Electrocatalytic Reduction of Hexavalent Chromium

09-Nov-2015 | Qinghua Ji; Dawei Yu; Gong Zhang; Huachun Lan; Huijuan Liu; Jiuhui Qu, Environmental Science & Technology, 2015

Owing to its high efficiency and environmental compatibility, electroreduction holds great promise for the detoxification of aqueous Cr(VI). However, the typical electroreduction system often shows poor mass transfer, which results in slow reduction kinetics and hence higher energy consumption. ...


Separation of toxic coralene red dye using ionic liquid with triton X‐114

06-Nov-2015 | Darshak R. Bhatt, Kalpana C. Maheria, Jigisha Parikh, Environmental Progress, 2015

Cloud point extraction was carried out to remove Coralene red (CR) dye from aqueous solution using tetra ethyl ammonium tetrafluoroborate [TEA(BF4)] ionic liquid as an additive with non‐ionic surfactant Triton X‐114. The effects of different operating parameters such as concentration of ...
