Publikováno v: Water Research X, Vol 25, Iss , Pp 100260- (2024)

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 nanoparticles (N

Integrated urban water management by coupling iron salt production and application with biogas upgrading

Autor: Zhetai Hu, Lanqing Li, Xiaotong Cen, Min Zheng, Shihu Hu, Xiuheng Wang, Yarong Song, Kangning Xu, Zhiguo Yuan

Publikováno v: Nature Communications, Vol 14, Iss 1, Pp 1-12 (2023)

Abstract Integrated urban water management is a well-accepted concept for managing urban water. It requires efficient and integrated technological solutions that enable system-wide gains via a whole-of-system approach. Here, we create a solid link be
