Treatment of high-strength wastewater is critical for the aquatic environment and receiving water bodies around the globe. Untreated or partially treated high-strength wastewater may cause severe damage to the existing water bodies. Various high-rate anaerobic bioreactors have been developed in the last decades for treating high-strength wastewater. High-rate anaerobic bioreactors are effective in

Robustness of the synergistic partial-denitrification, anammox, and fermentation process for treating domestic and nitrate wastewaters under fluctuating C/N ratios J. Environ. Manag. (IF 8.7) Pub Date : 2024-03-06 Jiantao Ji, Ying Zhao, Zhixuan Bai, Jing Qin, Haosen Yang, Feiyue Hu, Zhaoxu Peng, Baodan Jin, Xiaoxuan Yang
The synergistic partial-denitrification, anammox, and fermentation (SPDAF) process presents a promising solution to treat domestic and nitrate wastewaters. However, its capability to handle fluctuating C/N ratios (the ratios of COD to total inorganic nitrogen) in practical applications remains uncertain. In this study, the SPDAF process was operated for 236 days with C/N ratios of 0.7–3.5, and a high

Soil-mustard revitalization via rice husk ash, a promising soil amendment material for sustainable management of heavy metal contamination in tropical ecosystem J. Environ. Manag. (IF 8.7) Pub Date : 2024-03-06 Prince Kumar Singh, Indrajeet Kumar, Umesh Kumar, Rajesh Kumar Sharma
Prolonged wastewater irrigation in agriculture has led to the accumulation of heavy metals in soil, endangering both the soil quality and food safety, thereby posing a potential threat to human health through the consumption of contaminated crops. The present study aimed to enhance the yield of mustard ( L. cv. Varuna and NRCHB 101) plants and stabilize heavy metals (Cd, Cr, Ni, Cu, and Zn) in wastewater-irrigated

The impact of regional policy implementation on the decoupling of carbon emissions and economic development J. Environ. Manag. (IF 8.7) Pub Date : 2024-03-06 Xiaoyue Ma, Congyu Zhao, Chenchen Song, Danni Meng, Mei Xu, Ran Liu, Yamin Yan, Zhengguang Liu
The contradiction between economic growth demands and the achievement of the “dual-carbon” goals at the regional level is a pressing issue in China. As a significant economic and cultural center in the western region of China, the Guanzhong Plain urban agglomeration has experienced rapid development and urbanization, making it one of the key areas for national development. Therefore, greater attention

Synergistic evolution of water-energy-food system resilience and efficiency in urban agglomerations J. Environ. Manag. (IF 8.7) Pub Date : 2024-03-06 Hui An, Xiangyang Li, Jin Huang, Hailin Wu
With increasing internal and external risks to the WEF system, a single emphasis on efficiency or a lopsided pursuit of resilience can lead to difficulties in adapting to complex changes and resource redundancy. Revealing the synergistic evolutionary characteristics between efficiency and resilience of the WEF system is an effective method to deal with systemic internal and external risks. However

Rooibos tea waste binary oxide composite: An adsorbent for the removal of nickel ions and an efficient photocatalyst for the degradation of ciprofloxacin J. Environ. Manag. (IF 8.7) Pub Date : 2024-03-06 Opeoluwa I. Adeiga, Kriveshini Pillay
In this study, rooibos tea waste (RTW) incorporated with a binary oxide (BO; FeO–SnO) has been reported for the first time as a highly efficient adsorbent material for the elimination of Ni(II) ions. The as-synthesised rooibos tea waste-binary oxide (RWBO) composite adsorbent was characterised using miscellaneous techniques such as FTIR, XRD, SEM, EDX, TGA, BET, and XPS. The RWBO was then tested for

From single-chamber to multi-anodic microbial fuel cells: A review J. Environ. Manag. (IF 8.7) Pub Date : 2024-03-06 Soumyadeep Bhaduri, Manaswini Behera
Microbial fuel cells (MFCs) present a promising solution for wastewater treatment with the added benefits of energy generation, less sludge production and less energy consumption. MFCs have demonstrated high efficiency in the degradation of diverse types of wastewater. Nevertheless, the relatively low power density exhibited by MFCs has imposed certain restrictions on their widespread implementation

Nonlinear differential equations and their application to evaluating the integrated impacts of multiple parameters on the biochemical safety of drinking water J. Environ. Manag. (IF 8.7) Pub Date : 2024-03-06 Xiao Chen, Xiao-Nan Wu, Jing-Chun Feng, Yi Wang, Xiao-Chun Zhang, Yi-Lei Lin, Bin Wang, Si Zhang
The present study aimed to narrow such gaps by applying nonlinear differential equations to biostability in drinking water. Biostability results from the integrated dynamics of nutrients and disinfectants. The linear dynamics of biostability have been well studied, while there remain knowledge gaps concerning nonlinear effects. The nonlinear effects are explained by phase plots for specific scenarios
