In this work, the ozonation properties of 2,2',3',4,5-pentachlorodiphenyl sulfide (PeCDPS) was systematically studied, with special emphasis on the underlying mechanism for the effects of inorganic ions. Kinetic experiments show that common ions can significantly reduce the oxidative properties of ozone, except for SO32- and Cu2+. The inhibition ef...

In this study, the fate of organophosphate esters (OPEs) in conventional and advanced drinking water treatment plants (DWTPs) was investigated in field scale. In addition, the risk of OPEs by drinking water was assessed. The average total OPE concentrations in raw and treated water were lower in the rainy season (94.3 and 57.1 ng/L, respectively) t...

The presence of contaminants of emerging concern (CECs) in various water bodies and the associated threats to eco-system and human society have raised increasing concerns. To fight against such a problem, TiO2 photocatalysis is considered to be a powerful tool. In recent decades, TiO2 nanotube array (TNA) fabricated by electrochemical anodization e...

This research work investigates the Zn2+, Cu2+ and Mg2+ inhibiting effects on CaCO3 precipitation. The results demonstrate a synergetic effect of the Cu2+-Zn2+-Mg2+ mixture by a long (infinite) induction time. The individual inhibition action of Cu2+, Zn2+ and Mg2+ is well-established, but it is much lower than the effect of the mixture. A dual mec...

Understanding the transport behaviors of thallium (Tl) in porous media is of considerable interest for both natural soils and artificial filtration removal of Tl. In this context, the transport behaviors of Tl(I) in water-saturated sand columns under different conditions were systematically investigated. It was found that, in addition to the effect...

Reservoirs are an important source of atmospheric methane (CH4), a potent greenhouse gas. The Mekong, one of the largest Asian rivers, has been heavily dammed and can be a potential hotspot for CH4 emissions. While low diffusive CH4 flux was previously reported from cascading reservoirs in the Upper Mekong, the contribution of ebullition (bubbling)...

Although water produced by reverse osmosis (RO) filtration has low bacterial growth potential (BGP), post-treatment of RO permeate, which is necessary prior to distribution and human consumption, needs to be examined because of the potential re-introduction of nutrients/contaminants. In this study, drinking water produced from anaerobic groundwater...

Nanoplastics derived from degradation of micro- or macroplastics are emerging contaminants in aquatic environments, where their fate and transport as well as toxicity are affected by aggregation. This study employed time-resolved dynamic light scattering to investigate the aggregation kinetics of polystyrene nanoplastics (PSNPs) in the presence of ...

Chlorine dioxide (ClO2) can be used as a pre-oxidant when chloramination is performed in water treatment plants. However, the effects of ClO2 pre-oxidation on the formation of nitrogenous disinfection by-products, such as dichloroacetonitrile (DCAN) and dichloroacetamide (DCAcAm), during chloramination are not well understood. In this study, the ef...

Nitrogen plays a central role in the sewer ecosystem, and the bioconversion of nitrogen can significantly affect bioreactions in sewers. However, the mechanisms underlying the involvement of nitrogen-associated pollutants in sewer ecosystems remain unknown. In this study, the effects of two typical nitrogen ratios (organic/inorganic nitrogen: 7/3 (...
