Transformation products of diclofenac: Formation, occurrence, and toxicity implication in the aquatic environment Water Res. (IF 11.4) Pub Date : 2024-09-04 Katarzyna Nosek, Dongye Zhao
Diclofenac (DCF) is the first drug on the EU Watch List of Priority Substances due to its extensive uses, incomplete removal in wastewater treatment plants (WWTPs), and toxic effects. Once in the environment, DCF undergoes processes that yield various transformation products (TPs) or metabolites, whichcan be more toxic than DCF. While these TPs or metabolites often dominate the majority of the drug

Persistent free radicals in natural organic matter activated by iron particles enhanced disinfection byproduct formation Water Res. (IF 11.4) Pub Date : 2024-09-03 Xinyi Qin, Yitian He, Shuming Liu, Baoyou Shi
The widespread presence of iron (Fe) particles and natural organic matter (NOM) in drinking water distribution systems (DWDS) can significantly affect tap water quality, contributing to aesthetic issues and potentially generating harmful disinfection byproducts (DBPs). This study revealed that Fe particles, when combined with humic acid (HA), substantially increased DBP formation during chlorination

Influences of wildfire on the soil dissolved organic matter characteristics and its electron-donating capacity Water Res. (IF 11.4) Pub Date : 2024-09-03 Sihua Zhu, Peijie Yang, Yongguang Yin, Siqi Zhang, Jitao Lv, Shanyi Tian, Tao Jiang, Dingyong Wang
Global increases in the intensity and frequency of wildfires are driving major changes in soil organic matter (SOM) characteristics, including soil dissolved organic matter (DOM). As the most crucial component of SOM, soil DOM plays a pivotal role in the carbon cycle and regulates the environmental fate of contaminants through its versatile reactivities, including electron-donating capacity (EDC).

Experimental and modeling insights into mixing-limited reactive transport in heterogeneous porous media: Role of stagnant zones Water Res. (IF 11.4) Pub Date : 2024-09-03 Maosheng Yin, Michele Lancia, Yong Zhang, Wenhui Qiu, Chunmiao Zheng
The understanding of mixing-controlled reactive dynamics in heterogeneous porous media remains limited, presenting significant challenges for modeling subsurface contaminant transport processes and for designing cost-effective environmental remedial efforts. The complexity of accurately observing, measuring, and modeling mixing-limited reactive transport has led to inadequate exploration of these critical

Insights into the role of electrochemical stimulation on sulfur-driven biodegradation of antibiotics in wastewater treatment Water Res. (IF 11.4) Pub Date : 2024-09-03 Haoting Quan, Yanyan Jia, Huiqun Zhang, Fahui Ji, Yongsen Shi, Qiujin Deng, Tianwei Hao, Samir Kumar Khanal, Lianpeng Sun, Hui Lu
The presence of antibiotics in wastewater poses significant threat to our ecosystems and health. Traditional biological wastewater treatment technologies have several limitations in treating antibiotic-contaminated wastewaters, such as low removal efficiency and poor process resilience. Here, a novel electrochemical-coupled sulfur-mediated biological system was developed for treating wastewater co-contaminated

Enhancing energy and nitrogen removal efficiency through automatic split injection and innovative aeration device: A study of low C/N ratio environments Water Res. (IF 11.4) Pub Date : 2024-09-03 Byeongwook Choi, Tae-In Kim, Hoo Hugo Kim, Chang-Min Kim, Sanghun Park, Sungjong Lee
A new aeration device based on Bernoulli's principle, Jetventrumixer (JVM), was introduced into an aeration tank in denitrification process, which involved an automatic split injection system (ASIS) into two denitrification tanks every 10 minutes. Real-time monitoring of influent water allowed the calculation of the C/N ratio, enhancing the utilization efficiency of internal carbon sources while reducing

Leaching behavior of microplastics during sludge mechanical dewatering and its effect on activated sludge Water Res. (IF 11.4) Pub Date : 2024-09-03 Xingfeng Yang, Shiyu Niu, Man Li, Yulong Niu, Kailiang Shen, Bin Dong, Jin Hur, Xiaowei Li
Dewatering is an indispensable link in sludge treatment, but its effect on the microplastics (MPs) remains inadequately understood. This study investigated the physicochemical changes and leaching behavior of MPs during the mechanical dewatering of sludge, as well as the impact of MP leachates on activated sludge (AS). After sludge dewatering, MPs exhibit rougher surfaces, decreased sizes and altered

Acidic proteomes are linked to microbial alkaline preference in African lakes Water Res. (IF 11.4) Pub Date : 2024-09-03 Minglei Ren, Ang Hu, Lu Zhang, Xiaolong Yao, Zhonghua Zhao, Ismael Aaron Kimirei, Jianjun Wang
Microbial amino acid composition (AA) reflects adaptive strategies of cellular and molecular regulations such as a high proportion of acidic AAs, including glutamic and aspartic acids in alkaliphiles. It remains understudied how microbial AA content is linked to their pH adaptation especially in natural environments. Here we examined prokaryotic communities and their AA composition of genes with metagenomics

Influential mechanism of water occurrence states of waste-activated sludge: Specifically focusing on the pore characteristics dominated by cation-organic interactions Water Res. (IF 11.4) Pub Date : 2024-09-03 Boran Wu, Wei Ye, Ningrui Yu, Hewei Li, Kun Zhou, Xiaoli Chai, Xiaohu Dai
The solid pore characteristics are commonly considered as the important influential factors on waste-activated sludge (WAS) dewaterability, and should be related to the cohesive force of bio-flocs dominated by cation-organic interactions at solid-water interface. This study aimed to establish an approach for regulating the solid pore structure of WAS by cationic regulation. The influential mechanism
