Aquatic photochemical kinetics of benzotriazole and structurally related compounds

25-Mar-2015 | Elisabeth Janssen; Emily Marron; Kristopher McNeill, Journal of Environmental Monitoring, 2015

Benzotriazole corrosion inhibitors are not completely removed during wastewater treatment and are frequently detected in surface waters. Here, the photochemical kinetics of benzotriazoles and structurally related compounds were assessed for natural aqueous environments. The direct photochemical ...

Distribution, partition and removal of polycyclic aromatic hydrocarbons (PAHs) during coking wastewater treatment processes

25-Mar-2015 | Wanhui Zhang; Chaohai Wei; Guanfeng An, Journal of Environmental Monitoring, 2015

In this study, we report the performance of full-scale conventional activated sludge (A/O1/O2) treatment in eliminating polycyclic aromatic hydrocarbons (PAHs). Both aqueous and solid phases along with the coking wastewater treatment processes were analyzed for the presence of 18 PAHs. It was ...

Design of PAMAM-COO Dendron-Grafted Surfaces to Promote Pb(II) Ion Adsorption

25-Mar-2015 | Leebyn Chong; Meenakshi Dutt, Physical Chemistry Chemical Physics, 2015

An expanding area of green technology is in the wastewater treatment for heavy metal ions. As the adsorption of cations to solid surfaces has been proven to be successful, recent research has demonstrated enhanced adsorption profiles by dendron brushes grafted onto a solid support. Via the ...

Highly Efficient Forward Osmosis Based on Porous Membranes—Applications and Implications

19-Mar-2015 | Saren Qi; Ye Li; Yang Zhao; Weiyi Li; Chuyang Y. Tang, Environmental Science & Technology, 2015

For the first time, forward osmosis (FO) was performed using a porous membrane with an ultrafiltration (UF)-like rejection layer and its feasibility for high performance FO filtration was demonstrated. Compared to traditional FO membranes with dense rejection layers, the UF-like FO membrane was 2 ...

Non‐thermal plasma degradation of dye using an underwater dielectric barrier discharge created inside a porous hydrophobic ceramic tube

12-Mar-2015 | Jin‐Oh Jo, Soo Hyoung Moon, Young Sun Mok, Coloration Technology, 2015

An alternating‐current‐driven, atmospheric‐pressure, non‐thermal plasma reactor was applied to the degradation of dye in water. The plasma reactor, made of a porous hollow ceramic tube, was placed underwater and was able to disperse plasmatic gas containing various reactive species into aqueous ...

Microbial Community Analysis of Anaerobic Reactors Treating Soft Drink Wastewater

06-Mar-2015 | Takashi Narihiro et al., PLoS ONE, 2015

by Takashi Narihiro, Na-Kyung Kim, Ran Mei, Masaru K. Nobu, Wen-Tso Liu The anaerobic packed-bed (AP) and hybrid packed-bed (HP) reactors containing methanogenic microbial consortia were applied to treat synthetic soft drink wastewater, which contains polyethylene glycol (PEG) and fructose as ...
