Ling-Yu Luan, Li Zhang, Li-Hong Wang
Synthesized organobentonite (SOB), montmorillonite (MMT), and commercial organobentonite (COB) were used as adsorbents for paraffin oil, a model pollutant in land-based oil spills and oil pipeline rupture. The characterization of clays was carried out with scanning electron microscopy (SEM), thermogravimetric analysis (TG), Fourier transform infrared spectroscopy (FTIR), and X-ray diffraction (XRD). After adsorption, oil was separated from adsorbents with a carbon dioxide responsive solvent N,N-dimethylcyclohexylamine (DMCHA), and DMCHA was subsequently separated from paraffin oil upon CO2 bubbling instead of distillation with high energy cost...

High concentrations of grease easily inhibit anaerobic digestion. The stability of the process and microbial responses in the controlling internal circulation (CIC) reactor used for treating food waste were investigated under different grease contents and inner circulation ratios. Results showed that at the grease content of 1 g/L, the removal rates of 94% and 86-93% were achieved for chemical oxygen demand (COD) and NH3 -N, respectively. In contrast, when the grease content increased to 7 g/L, removal rates for COD and NH3 -N significantly decreased to 42...

Occurrence and fate of sewage- and sludge-borne total mercury (THg) and methylmercury (MeHg) have received little attention, although they might be an important component of the global Hg inventory. To address the knowledge gap, sewage and sewage sludge (SS) samples were collected from a secondary municipal sewage treatment plant (MSTP) located in Jiaozuo, China. Total Hg in the raw sewage varied between 95.3 ng/L and 1.2 × 103  ng/L, while MeHg occurred in the sewage within ranges of 2.7-21.3 ng/L...

Impacts of red beet consumption both on human and animal health are subject of intense research. In particular, products that are not heat-processed contain plethora of bioactive compounds that hold promise against numerous degenerative and aging-associated diseases. However, high level of nitrates (typically more than 2 g NO3 - kg-1 ) whose health effects are perceived with reasoned objections counterbalance these benefits. Following the above, from a certain level, the increased consumption of red beet has contrary impacts, creating a limiting factor not only from the economic point of view but also in terms of beneficial compounds intake...

Coalbed natural gas (CBNG) is an important unconventional natural gas resource with large reserves in China and receives much attention these years. The CBNG production is accomplished by extracting large volumes of produced water from the aquifer. The CBNG-produced water is commonly managed by discharging into nearby disposal ponds in the Southern Qinshui Basin (SQB), which provides an opportunity for water source for nearby irrigation, livestock, wildlife, and human drinking water. However, utilization of this nontraditional water source in the SQB is hindered by limited knowledge of water quality, practically oxidation/reduction potential (OPR), electrical conductivity (EC), sodium adsorption ration (SAR), and trace element chemistry data...

Methylmercury (MeHg) is a highly toxic environmental pollutant which binds with a high affinity to selenol groups. In view of this, seleno-compounds have been investigated as MeHg antidotes. In the present study, we evaluated the effects of the co-exposure to MeHg and the seleno-compound diphenyl diselenide (PhSe)2 on Drosophila melanogaster. We measured the survival rate, developmental survival, locomotor ability, reactive oxygen species (ROS) production, and Hg levels in D. melanogaster exposed to MeHg and/or (PhSe)2 in the food...

Natural organic matter (NOM) in micro-polluted water purification using membranes is a critical issue to handle. Understanding the fouling mechanism in the forward osmosis (FO) process, particularly identifying the predominant factor that controls membrane fouling, could have significant effects on exerting the advantages of FO technique. Cellulose triacetate no-woven (CTA-NW) membrane is applied to experiments with a high removal efficiency (> 99%) for the model foulant. Tannic acid (TA) is used as a surrogate foulant for NOM in the membrane fouling process, thus enabling the analysis of the effects of physical and chemical aspects of water flux, retention, and adsorption...

This study was conducted to assess the feasibility of using Moringa oleifera Lam. (MO) seeds in the biosorption of nitrate present in aqueous solutions by means of batch and fixed-bed column biosorption processes. The batch assays showed that nitrate biosorption is enhanced under experimental conditions of pH 3 and a biosorbent mass of 0.05 g. For the experiments in dynamic mode, the results obtained from the statistical parameters showed that lesser pH, lesser feed flow rate, and higher initial concentration will result in an increase of the maximum capacity of the bed...
