Summary: This study reports the effective degradation of halogenated aromatic disinfection byproducts (DBPs) by ZVI/Cu and establishes a novel mechanism-based quantitative structure-activity relationship model to predict degradation rate constants. The study found that ZVI/Cu can effectively degrade not only aliphatic DBPs but also new emerging aromatic DBPs formed in chlorinated and chloraminated drinking water. A quantitative structure-activity relationship model was developed to predict the degradation rate constants of other aromatic DBPs, and optimized descriptors were identified.

Summary: The degradation of roxarsone (ROX) via UV-based advanced oxidation processes (AOPs) was investigated, with UV/PDS being the most effective in removing ROX and UV/H2O2 being the most effective in reducing total organic carbon (TOC). The degradation of ROX follows a pseudo-first-order kinetics model, with a significant enhancement observed at pH 11.0 in UV/PMS process.

Summary: This study investigated a control strategy for spore-forming bacteria (SFB) in drinking water treatment. The results showed that pre-oxidation, coagulation sedimentation, and UV-AOPs inactivation were effective in transforming, removing, and inactivating SFB spores. The study also demonstrated the enhanced inactivation of the most chlorine-resistant SFB strain by adding chemicals to the UV irradiation process. The findings provide valuable references for dealing with SFB outbreak risk in drinking water treatment.

Summary: This study investigated the degradation of 2,4-diaminobutyric acid (DAB) in UV and UV/chlorine system, as well as the formation of disinfection byproducts (DBPs) during post-chlorination. The presence of reactive substances in the UV/chlorine system enhanced the degradation of DAB, but also increased the production of DBPs and their precursors. Factors such as UV irradiation time, pH, and Cl-2/N concentration affected the formation of DBPs during post-chlorination. Carbonaceous DBP precursors were mainly formed during UV irradiation, while nitrogenous DBP precursors were mainly formed during the UV/chlorine system. Brominated DBPs were dominant in the presence of bromide, while the formation of chlorinated DBPs was inhibited.

Summary: A recent study found that aromatic DBP fractions are the main contributors to the toxicity of chlorinated drinking water. However, the key drivers of toxicity based on the formation of aliphatic and aromatic DBPs in drinking water have not been comprehensively evaluated. This study explored the occurrence of various aliphatic and aromatic DBPs in drinking water samples from a Chinese megacity. The findings suggest that haloacetonitriles and halonitrophenols are the main toxicity drivers among the measured aliphatic and aromatic DBPs, respectively.

Summary: Ensuring drinking water quality is crucial for public health, especially in the context of increasing industrialization. Disinfection is a key process, but it leads to the formation of unwanted disinfection byproducts (DBPs) that negatively impact human health. Stricter regulations and techniques for DBP removal have been developed, but further research is needed to monitor and control these contaminants in water distribution systems.

Summary: One negative aspect of landfilling is the production of multicomponent dark liquids containing various chemical pollutants. Effective treatment methods like UV/Fe2+/H2O2 and UV/Fe2+/S2O82- processes are evaluated for degradation of landfill leachate. Factors such as [Fe2+]/[Oxidant] ratio, UV light, dosing mode, and pretreatment by a physicochemical process are examined for their influence. Best removal efficiencies for COD, TOC, and color index are achieved under specific operating conditions, with UV/Fe2+/S2O82- process showing better performance despite the influence of sulfate radical selectivity.

Summary: Iodinated disinfection byproducts (I-DBPs) are a emerging concern in water treatment due to high toxicity and taste-and-odor issues associated with iodinated trihalomethanes (I-THMs). UV irradiation effectively inactivates microorganisms in water, but can lead to the formation of I-DBPs through the transformation of iodine sources. UV and UV-based advanced oxidation processes (UV-AOPs) are suitable for I-DBP degradation, although high UV doses are required.

Summary: This study investigated the contributions of rotifers and nematodes to the biodegradable dissolved organic carbon (BDOC), bacterial regrowth potential (BRP), and disinfection by-products (DBPs) in drinking water. The sheltering effects of chlorine-resistant invertebrates on indigenous and pathogenic bacteria were studied, and the health risk posed by invertebrates in drinking water was assessed. The results showed that nematodes have a significant sheltering effect on bacteria, reducing the effectiveness of chlorine and UV disinfection. The study aims to provide a theoretical basis and technical support for risk control and safety standards for invertebrates in drinking water.

Summary: Chlorine quenchers are used to prevent the reactions between disinfection byproducts (DBPs) and residual chlorine in drinking water. However, some chlorine quenchers may result in dechlorination of DBPs. Phenolic compounds, which are highly toxic DBPs, pose a significant threat to drinking water safety. The impact of popular chlorine quenchers on phenolic DBPs is not well understood.

Summary: In recent years, the combination of UV irradiation and chlor(am)ination process has been widely used in secondary water supply systems in many cities of China. The study found that DBPs formation in a UV-activated MCCS is influenced by factors such as the mass ratios of free chlorine to NH2Cl, pH values, NOM types, and Br- concentration. It was observed that DBPs formation decreased significantly as the mass ratio of free chlorine to NH2Cl changed. Additionally, DBPs formation was highest in water containing humic acid (HA) compared to fulvic acid (FA) and algal organic matter (AOM).

Summary: In this study, the removal of dye ADMI from raw textile wastewater was investigated using magnetic multi-walled carbon nanotubes-loaded alginate. The key factors, including pH, adsorbent dose, and contact time, were optimized using response surface methodology-based central composite face-centred design. The adsorbents were characterized using various techniques. The developed model fit well with the experimental data, and under the optimized conditions, a high removal efficiency and ADMI adsorption capacity were achieved. The adsorption process was found to be monolayer and chemical in nature. The adsorption mechanism could be explained by the presence of negatively charged carboxyl and hydroxyl groups on the surface of the adsorbent.

The results showed that optimization of disinfection factors had a significant effect on planktonic cells of P. aeruginosa but not on the biofilm. The concentration of NaOCl and CAT was more effective than pH in inactivating planktonic and biofilm cells. However, the use of chlorine compounds based on recommended levels did not prevent the formation of P. aeruginosa biofilm.

Summary: This study evaluates the performance of ozonation and adsorption as in-series processes compared to standalone processes for the removal of Contaminants of Emerging Concern (CECs) in drinking water. The combination of both processes proves to be more effective than adsorption and ozonation alone. Ozonation improves the adsorption performance of poorly-oxidizable CECs but worsens that of well-oxidizable compounds. This research highlights the importance of considering both processes in the removal of CECs in drinking water treatment plants.

China has adopted sponge city as an efficient means of preventing and controlling urban floods. Using a SWMM-FVCOM model, the hydrological reduction and control effect of sponge city construction (SPCC) within a university campus were evaluated. The study found that implementing SPCC effectively mitigates surface runoff and reduces the severity of urban flooding. However, the efficacy of runoff control decreases with longer rainfall return periods.
