Nitrogen-cycling microorganisms play essential roles in biological wastewater treatment, where nitrogen is removed with substantial energy and chemical consumption and greenhouse gas emissions. The discoveries of new nitrogen-cycling microorganisms paved the way for a remarkable paradigm shift from energy-negative and carbon-positive to energy-positive and carbon-neutral wastewater management. This Review reflects on the trajectory of these microbial discoveries and summarizes the technological progress enabled by them thus far. By bridging the gap between environmental microbiologists and water engineers, who are both interested in these new nitrogen-cycling microorganisms but with different focuses and expertise, this Review acknowledges the challenges encountered and illuminates the exciting future ahead. The continued close collaboration between scientists and engineers will keep redefining the landscape of wastewater management. This Review highlights how the discovery of new nitrogen-cycling microorganisms paves the way for process iterations and technological innovations towards sustainable wastewater management.

Here we delve into the challenges and innovative strategies for achieving net-zero emissions in the wastewater sector, a notable source of global greenhouse gases. Unlike other infrastructure sectors, wastewater management involves complex and variably quantifiable emissions across all scopes, making standardization difficult. This study provides a global overview of the sector’s emissions profiles by leveraging literature mining, data analysis and case studies. It emphasizes the substantial variability in emissions, identifies key emission sources and locations, and advocates for tailored monitoring and mitigation strategies. It highlights the potential emissions shifting across scopes due to the adoption of new technologies and accounting practices, and it argues for a holistic analysis for optimization and integration to ensure a net benefit of the overall reductions in carbon footprints. This study underscores the urgency of rethinking current practices to align with ambitious mid-century net-zero targets, emphasizing the critical role of accurate emissions quantification and comprehensive decarbonization strategies. This Review offers a comprehensive global overview of greenhouse gas emissions in the wastewater sector, highlighting key gaps in emission quantification and mitigation. It explores current decarbonization strategies, emphasizes the complexity of emissions across all scopes, and advocates for tailored monitoring, holistic analysis and strong support from different stakeholders to drive effective mitigation and achieve net-zero emissions.
在此,我们将深入探讨在全球温室气体的主要来源--污水处理领域实现净零排放所面临的挑战和创新战略。与其他基础设施行业不同,废水管理涉及复杂且可量化的各种排放,因此很难实现标准化。本研究通过文献挖掘、数据分析和案例研究,概述了该行业的全球排放概况。它强调了排放量的巨大差异,确定了主要排放源和排放地点,并倡导量身定制的监测和减缓战略。它强调了由于采用新技术和核算方法而可能造成的不同范围的排放转移,并主张进行整体分析以实现优化和整合,从而确保碳足迹整体减少的净效益。本研究强调了重新思考当前做法以实现本世纪中期净零排放宏伟目标的紧迫性,同时强调了准确的排放量化和全面的去碳化战略的关键作用。本报告全面概述了全球污水行业的温室气体排放情况,强调了排放量化和减排方面的主要差距。它探讨了当前的去碳化战略,强调了所有范围内排放的复杂性,并提倡有针对性的监测、整体分析和不同利益相关方的大力支持,以推动有效减排并实现净零排放。

Direct-drive photovoltaic electrodialysis via flow-commanded current control 通过流量指令电流控制直接驱动光伏电渗析技术

Renewable powered, brackish groundwater desalination is an underutilized resource in the developing world, where there are unreliable energy sources and reliance on increasingly saline groundwater. Traditional renewable desalination technologies require sizable energy storage for sufficient water production, leading to increased cost, maintenance and complexity. We theorize and demonstrate a simple control strategy—flow-commanded current control—using photovoltaic electrodialysis (PV-ED) to enable direct-drive (little to no energy storage), optimally controlled desalination at high production rates. This control scheme was implemented on a fully autonomous, community-scale (2–5 m3 d−1) PV-ED prototype system and operated for 6 months in New Mexico on real brackish groundwater. The prototype fully harnessed 94% of the extracted PV energy despite featuring an energy storage to water productivity ratio of over 99% less than the median PV desalination systems in literature. Flow-commanded current control PV-ED provides a simple strategy to desalinate water for resource-constrained communities and has implications for decarbonizing larger, energy-intensive desalination industries. Desalination of brackish water powered by renewable energy sources is a promising approach to obtain clean water in environmentally constrained communities, but high energy storage requirements hamper its development. Direct-drive photovoltaic electrodialysis is now shown to efficiently produce desalinated water while requiring minimal energy storage.
在发展中国家,可再生能源、咸水地下水淡化是一种未得到充分利用的资源,因为那里的能源不可靠,而且依赖于日益含盐的地下水。传统的可再生海水淡化技术需要大量的能量储存才能产生足够的水,从而导致成本、维护和复杂性的增加。我们从理论上提出并演示了一种简单的控制策略--流量指令电流控制--利用光伏电渗析(PV-ED)实现直接驱动(几乎不需要储能),并以高生产率对海水淡化进行优化控制。该控制方案在一个完全自主的社区级(2-5 立方米/天)光伏电渗析原型系统上实施,并在新墨西哥州的真实咸水地下水上运行了 6 个月。该原型系统充分利用了 94% 的光伏提取能量,尽管其储能与水生产力的比率比文献中的中位光伏海水淡化系统低 99%。流量指令电流控制光伏海水淡化系统为资源有限的社区提供了一种简单的海水淡化策略,并对大型能源密集型海水淡化行业的去碳化产生了影响。以可再生能源为动力的苦咸水淡化是在环境受限社区获得清洁水的一种很有前景的方法,但高储能要求阻碍了它的发展。直接驱动光伏电渗析技术现已证明能够高效生产淡化水,同时只需极少的能量储存。

Accelerated low-temperature, low-fouling brine concentration through evaporative ion exchange mediated by the effect of functional groups 在官能团效应的介导下,通过蒸发离子交换加速低温低垢盐水浓缩
Pub Date : 2024-10-03 DOI: 10.1038/s44221-024-00305-7

Achieving brine concentration by membrane distillation or the various humidification–dehumidification processes that are currently available always requires a thermal energy input and an elevated temperature. In this study, we developed a brine concentration process mediated by the unique osmotic and evaporation properties of high-capacity ion exchange resins. The evaporative ion exchange process consists of two steps. First, when a concentrated salt solution is brought into contact with a relatively dry, high-capacity polymeric ion exchanger, water selectively permeates into the ion exchanger phase through osmosis and the resin swells. In the second step, water evaporates when the swollen ion exchanger is brought into contact with air with low relative humidity and the resin shrinks. Here we show that, with hypersaline produced water from Marcellus gas shale, this evaporative ion exchange process attained total dissolved solids greater than 400,000 mg l−1, leading to the precipitation/crystallization of barium and sodium chloride at ambient temperature without causing any fouling of the ion exchange resins. The evaporative ion exchange process developed in this study achieves brine concentration at ambient temperature without fouling, providing a non-thermal brine concentration technology towards zero liquid discharge.
通过膜蒸馏或现有的各种加湿-除湿工艺实现盐水浓缩,始终需要热能输入和较高的温度。在这项研究中,我们利用高容量离子交换树脂独特的渗透和蒸发特性,开发了一种盐水浓缩工艺。蒸发离子交换过程包括两个步骤。首先,当浓盐溶液与相对干燥的高容量聚合物离子交换树脂接触时,水通过渗透作用选择性地渗入离子交换树脂相,树脂膨胀。在第二步中,当膨胀的离子交换剂与相对湿度较低的空气接触时,水分蒸发,树脂收缩。在这里,我们展示了在使用马塞勒斯页岩气的高盐度产水时,这种蒸发离子交换工艺可使溶解固体总量超过 400,000 毫克/升,从而在环境温度下沉淀/结晶出氯化钡和氯化钠,而不会造成离子交换树脂的任何污垢。本研究开发的蒸发离子交换工艺可在常温下实现盐水浓缩,且不会造成结垢,为实现零液体排放提供了一种非热盐水浓缩技术。
