Challenges and Experiences of Managed Aquifer Recharge in the Mexico City Metropolitan Area

open access: yesGroundwater, Volume 60, Issue 5, Page 675-684, September/October 2022., 2022
Abstract The Mexico City Metropolitan Area (MCMA) is a significant and important urban center in North America, covering an area of approximately 9500 km2 with a population of almost 23 million, yet the water supply remains unsustainable. The total water demand in the MCMA is 84 m3/s and is provided by groundwater (63% or 53 m3/s), imported water (27 ...

Influence of Fe2+ and Fe3+ on the Performance and Microbial Community Composition of a MFC Inoculated with Sulfate‐Reducing Sludge and Acetate as Electron Donor

open access: yesJournal of Chemistry, Volume 2022, Issue 1, 2022., 2022
A sulfidogenic sludge supplemented with acetate was evaluated in the anodic chamber of microbial fuel cells (MFCs) in the presence of sulfate (SO4-2)/Fe3+ and sulfate (SO4-2)/Fe2+ to investigate the MFC performance and the effect of the iron ions on the composition of the microbial community since sulfate and iron ions are frequently present in ...

Victims crossing overflowing watercourses with vehicles in Spain

open access: yesJournal of Flood Risk Management, Volume 13, Issue 4, December 2020., 2020
Abstract Heavy rainfall causes many watercourses to overflow. In these circumstances, crossing by car even on a road, can be extremely dangerous; however, dozens of drivers are swept away every year in their vehicles. This paper analyses this type of accident in Spain between 2008 and 2018, recording the date, location, number of victims, age and ...

Scaling factors in HYDRUS to simulate a reduction in hydraulic conductivity during infiltration from recharge wells and infiltration basins

open access: yesVadose Zone Journal, Volume 19, Issue 1, 2020., 2020
Abstract Managed aquifer recharge (MAR) represents a promising technique to cope with increasing water stress worldwide. However, it can be challenging to operate MAR systems, especially concerning clogging. Clogging reduces the infiltration capacity and system efficiency of a MAR facility.

Design Proposal of a Prototype for Sawdust Pellet Manufacturing through Simulation

open access: yesAdvances in Materials Science and Engineering, Volume 2020, Issue 1, 2020., 2020
Mexican industry generates tons of organic wastes that are not used and cause social, environmental, and health problems. The main organic residue which is generated during wood production is the sawdust (biomass). In order to reduce the problems generated by its waste, a prototype to manufacture biofuel pellets was designed by considering a flat die ...
