    The addition of chlorine to water increases the generation of disinfection by-products (DPBs). In this webinar we discuss with William Mitch (Stanford), Susan Richardson (South Carolina Univ) and Maria José Farré (ICRA, Barcellona) about high molecular weight DBPs, exploring the formation, potential environmental hazard and risk assessment.

    The UN 2023 Water Conference will be held in New York on March 22-24, 2023, To highlight the importance of research and scientific evidence in addressing the water-related challenges, we present a new compilation of research articles from across the Nature Portfolio that corresponds to the dialogue themes of the conference.

  • Nature Water talks march

    Ahead of the first global conference on water in almost 50 years, held on March 22-24, Karin Sjöstrand from Nat Water spoke to Quentin Grafton (Australian National University), Joyeeta Gupta (University of Amsterdam), John Matthews (AGWA), and Rachael McDonnell (IWMI) about expectations of this global event and about challenges and opportunities on the road ahead

  • The rapid urbanization in China calls for an expansion of urban wastewater treatment systems, which in turn may exacerbate climate impacts. With an extensive and integrated application of existing low-carbon technologies for wastewater treatment, sludge disposal and water reuse, it is possible to substantially decouple urban water stress mitigation from greenhouse gas emissions.

  • 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.

  • Wastewater-based epidemiology was widely used to monitor the spreading of COVID-19. We should now build on the knowledge acquired over the past three years to extend the use of the technique to a wide range of human health and lifestyle aspects.

  • The approach based on analysing wastewater to monitor drugs or pathogens in the population had been used for decades before it became widespread during the COVID 19 pandemic. We have asked experts located in a number of different nations to share their views on the potential and limitations of wastewater-based epidemiology in the future.

  • This study reveals trade-offs in freshwater savings, cost and capacity shortfalls from deploying treated brackish water for wet thermoelectric cooling, as well as its cost-effectiveness, relative to dry cooling retrofit, in saving freshwater.
