Anammox granular sludge (AnGS) serves as an important platform for cost-effective nitrogen removal from wastewater. Different to the traditionally sphere-like granules, a novel type of AnGS in a unique ellipsoid-like shape was obtained thro...
Near-Complete Phosphorus Recovery from Challenging Water Matrices Using Multiuse Ceramsite Made from Water Treatment Residual (WTR) [0.03%]
采用污水剩余污泥制备的多用途陶粒从复杂水基质中近完全回收磷
Jianfei Chen,Jinkai Xue,Jinyong Liu et al.
Jianfei Chen et al.
Water treatment residual (WTR) is a burden for many water treatment plants due to the large volumes and associated management costs. In this study, we transform aluminum-salt WTR (Al-WTR) into ceramsite (ASC) to recover phosphate from chall...
Modeling transient mixed flows in sewer systems with data fusion via physics-informed machine learning [0.03%]
基于物理信息的机器学习数据融合在下水道系统瞬态混流建模中的应用研究
Shixun Li,Wenchong Tian,Hexiang Yan et al.
Shixun Li et al.
Transitions between free-surface and pressurized flows, known as transient mixed flows, have posed significant challenges in urban drainage systems (UDS), e.g., pipe bursts, road collapses, and geysers. However, traditional mechanistic mode...
Rapid and selective quantitative colourimetric analysis of nitrite in water using a S-Nitrosothiol based method [0.03%]
一种基于S-硝基硫醇的快速选择性定量水体重氮盐色彩分析方法
E Latvyte,A Greenwood,A Bogush et al.
E Latvyte et al.
This study introduces a novel S-nitrosothiol based method for the rapid and highly selective detection of nitrite in complex water matrices. Sodium 3-mercapto-1-propanesulfonate forms a distinctive pink S-nitrosothiol compound upon interact...
Start-up of a full-scale two-stage partial nitritation/anammox (PN/A) process treating reject water from high solid anaerobic sludge digestion (HSAD) [0.03%]
高固体厌氧污泥消化液废水的两级部分硝化/厌氧氨氧化(PN/A)工艺的启动试验研究
Shuyan Zhou,Hui Gong,Enhui Xu et al.
Shuyan Zhou et al.
High solid anaerobic digestion (HSAD) achieves the benefits of high volumetric loading rates and lower reject water production, which, however, results in much more concentrated reject water with a remarkable increase in organics and nitrog...
The impact of blue-green infrastructure on trace contaminants: A catchment-wide assessment [0.03%]
蓝绿基础设施对痕量污染物的影响：流域范围内的评估
Marisa Poggioli,Giovan Battista Cavadini,Zhaozhi Zheng et al.
Marisa Poggioli et al.
Blue-green infrastructure (BGI) reduce urban combined sewer overflows (CSOs) and stormwater outlets (SWOs). However, most conventional BGI are not designed to remove trace organic contaminants. Little is known about the potential of convent...
An overlooked nanofluids effect from Fe3O4 nanoparticles enhances mass transfer in anammox granular sludge [0.03%]
Fe3O4纳米颗粒的常被忽略的纳米流体效应可增强厌氧氨氧化颗粒污泥中的质量传递过程
Dongdong Xu,Aqiang Ding,Yang Yu et al.
Dongdong Xu et al.
Magnetite (Fe3O4) particles have been widely reported to enhance the anammox's activity in anammox granular sludge (AnGS), yet the underlying mechanisms remain unclear. This study demonstrates that both Fe3O4 microparticles (MPs) and nanopa...
Adjusted bacterial cooperation in anammox community to adapt to high ammonium in wastewater treatment plant [0.03%]
厌氧氨氧化菌群落通过调整相互作用适应高浓度铵氮污水处理环境
Yiming Feng,Lingrui Kong,Ru Zheng et al.
Yiming Feng et al.
Bacterial cooperation is very important for anammox bacteria which perform low-carbon and energy-efficient nitrogen removal, yet its variation to adapt to high NH4 +-N concentration in actual wastewater treatment plants (WWTPs) remains uncl...
