Impact of thermal hydrolysis on VFA-based carbon source production from fermentation of sludge and digestate for denitrification: experimentation and upscaling implications Water Res. (IF 11.4) Pub Date : 2024-09-10 Andrea Carranza Muñoz, Jesper Olsson, Andriy Malovanyy, Christian Baresel, Nethra Machamada-Devaiah, Anna Schnürer
Stricter nutrient discharge limits at wastewater treatment plants (WWTPs) are increasing the demand for external carbon sources for denitrification, especially at cold temperatures. Production of carbon sources at WWTP by fermentation of sewage sludge often results in low yields of soluble carbon and volatile fatty acids (VFA) and high biogas losses, limiting its feasibility for full-scale application

Drought reduces nitrogen supply and N2O emission in coastal bays Water Res. (IF 11.4) Pub Date : 2024-09-10 Mingzhen Zhang, Dan Yu, Yiqi Yu, Ruifeng Yan, Yasong Li, Weijie Gong, Kai Xiao, Shaobin Li, Nengwang Chen
Severe droughts are increasingly prevalent under global climate change, disrupting watershed hydrology and coastal nitrogen cycling. However, the specific effects of drought on nitrogen transport from land to sea and subsequent nitrogen dynamics remain inadequately understood. In this study, we evaluated the consequences of the 2020–2022 drought on nitrogen supply and N2O emissions in Xiamen Bay, Southeast

Environmental fate and transport of PFAS in wastewater treatment plant effluent discharged to rapid infiltration basins Water Res. (IF 11.4) Pub Date : 2024-09-10 Kai M. Trobisch, Donald M. Reeves, Daniel P. Cassidy
Fate and transport of per- and polyfluoroalkyl substances (PFAS) in wastewater treatment plant (WWTP) effluent discharged to rapid infiltration basins (RIBs) is investigated using data from 26 WWTPs in Michigan, USA. PFAS were found to accumulate in groundwater downgradient from RIBs with median groundwater-effluent enrichment factors for ten commonly detected, terminal-form perfluoroalkyl acids (PFAAs)

Picolinic acid-mediated Mn(II) activated periodate for ultrafast and selective degradation of emerging contaminants: Key role of high-valent Mn-oxo species Water Res. (IF 11.4) Pub Date : 2024-09-10 Wenxin Shi, Chi Zhang, He Zhao, Bing Zhang, Heli Tang, Yanan Liu, Bing Zhang
The utilization of periodate (PI, IO4-) in metal-based advanced oxidation processes (AOPs) for the elimination of emerging contaminants (ECs) have garnered significant attention. However, the commonly used homogeneous metal catalyst Mn(II) performs inadequately in activating PI. Herein, we exploited a novel AOP technology by employing the complex of Mn(II) with the biodegradable picolinic acid (PICA)

Pilot-scale and large-scale Fenton-like applications with nano-metal catalysts: From catalytic modules to scale-up applications Water Res. (IF 11.4) Pub Date : 2024-09-10 Haoyun Lu, Lifei Hou, Yang Zhang, Xiaoqiang Cao, Xing Xu, Yanan Shang
Recently, great efforts have been made to advance the pilot-scale and engineering-scale applications of Fenton-like processes using various nano-metal catalysts (including nanosized metal-based catalysts, smaller nanocluster catalysts, and single-atom catalysts, etc.). This step is essential to facilitate the practical applications of advanced oxidation processes (AOPs) for these highly active nano-metal

Carbon chain elongation characterizations of electrode-biofilm microbes in electro-fermentation Water Res. (IF 11.4) Pub Date : 2024-09-08 Wei-Tong Ren, Zi-Lin He, Yang Lv, Hua-Zhe Wang, Lin Deng, Shan-Shan Ye, Juan-Shan Du, Qing-Lian Wu, Wan-Qian Guo
The higher efficiency of electro-fermentation in synthesizing medium-chain fatty acids (MCFAs) compared to traditional fermentation has been acknowledged. However, the functional mechanisms of electrode-biofilm enhancing MCFAs synthesis remain research gaps. To address this, this study proposed a continuous flow electrode-biofilm reactor for chain elongation (CE). After 225 days of operation, stable

Genome-resolved metagenomics reveals the nitrifiers enrichment and species succession in activated sludge under extremely low dissolved oxygen Water Res. (IF 11.4) Pub Date : 2024-09-08 Jiayuan Deng, Da Kang, Yongtang Zhang, Bolin Chen, Chaoyi Xia, Chen Yu, Yongzhen Peng
Nitrification, a process carried out by aerobic microorganisms that oxidizes ammonia to nitrate via nitrite, is an indispensable step in wastewater nitrogen removal. To facilitate energy and carbon savings, applying low dissolved oxygen (DO) is suggested to shortcut the conventional biological nitrogen removal pathway, however, the impact of low DO on nitrifying communities within activated sludge
