Drinking water infrastructure in urban settings is increasingly affected by population growth and disruptions like extreme weather events. The integration of direct wastewater reuse can help to maintain drinking water service when the system is compromised.
The potential hazard of per- and polyfluoroalkyl substances has led to new regulations affecting requirements for water quality. This Perspective proposes a protocol to adapt water treatment technology to meet new regulation requirements.
Functional relationships that capture the spatial co-variability of forcing and response variables provide a framework well-suited for global water model evaluation. Evaluating these relationships highlights large differences across models’ representations of the water cycle and the need for model improvement.
Access to sanitation is a fundamental right that is still missing, especially in many parts of low-income countries. This Perspective focuses on the impact of unclean school latrines on child health.
This Review identifies factors that lead to ‘unsafely managed sanitation’ in the United States, the specific types of access, and obstacles to characterizing and addressing the problem.
A hybrid photocatalyst–photothermal sheet can effectively harness sunlight to produce hydrogen fuel. At the same time, it can purify open-water sources such as seawater and industrial wastewater.
Crop switching optimization within the context of the Indo-Gangetic Plain provides compelling evidence that this approach yields significant benefits in terms of increasing calorie production and profits for farmers whilst minimizing water and energy use.
The adoption of open-hardware technology is changing current river research monitoring practices, reducing the need for scientists to allocate large portions of their budgets to expensive instrumentation.
Excavation and a geoarchaeological survey provide evidence of an early multi-levelled water management system in the Late-Holocene East Asian Monsoon region.
This Review presents an overview and analysis of biomimetic engineering principles and strategies for developing unique surface properties to design all-weather, portable water harvesting systems. It discusses key processes involved in water harvesting and proposes a framework for designing next-generation sustainable systems to alleviate freshwater scarcity.
Advanced oxidation or reduction processes (AOPs or ARPs) are effective techniques to remove contaminants and pathogens from water. This Review compares them with a new alternative process involving UV activation of low-molecular-weight diketones and explores the shift in water treatment technologies from discrete AOPs and ARPs to combined oxidation–reduction processes.
In this Review, Li and Wang utilize a unique chemical potential-based approach and critically analyse the available literature on sorption-based atmospheric water harvesting, including sorbents, processes and applications beyond water production.
The traditional solution–diffusion model, long used for studying water transport in reverse osmosis membranes, is re-evaluated with molecular dynamics simulations.
Efficiency is only one of the parameters involved in solar evaporation that should be improved to make it practical. Depending on the application, various factors of merit should be taken into consideration, as discussed in this Perspective.
