Advanced Treatment Strategies for Urban Wastewater: Quaternary Treatments for Safe Discharge and Potential Reuse

Ana I. Gomes

Urban wastewater treatment is increasingly expected to go beyond conventional compliance, addressing contaminants of emerging concern, microbial hazards, antimicrobial resistance-related elements, and residual organic matter. This shift has driven the development of quaternary treatment strategies designed not only to reduce the impact …

Integrated computational fluid dynamics and experimental evaluation of a tubular membrane photoreactor for UVC-driven advanced oxidation at bench- and pilot-scale

Carla S. Santos, Paulo H. Marrocos, Claudio Passalía, Marisol Daniela Labas et autres

This study combines computational fluid dynamics (CFD) simulations and experimental data to examine the hydrodynamic and photonic behavior of tubular membrane photoreactors operated under UVC and UVC/persulfate (UVC/PDS) conditions for the removal of organic micropollutants (OMPs). At bench-scale, CFD simulations revealed that …

Comparative evaluation of UV-driven processes for quaternary treatment of urban wastewaters: Trade-offs between micropollutants removal, toxicity reduction, and cost-effectiveness

Lúcio M.M.T. Gomes, Ana I. Gomes, Rosa Montes, José Benito Quintana et autres

Micropollutants (MP) in urban wastewater pose challenges, requiring advanced treatment solutions to ensure regulatory compliance and environmental safety. This study investigated UV-driven processes (UV-alone, UV/H 2 O 2 , and UV/PDS) in a FluHelik photoreactor operating in continuous mode (residence times: 1.0–6.5 …

19 Gelatin-functionalised hyaluronic acid-based hydrogels with antimicrobial peptides for chronic wound treatment

Nathalie Petit, Ana I. Gomes, Paula A. C. Gomes, S. Browne

Abstract Aim Chronic wounds including diabetic foot ulcers (DFU) develop due to impaired healing mechanisms associated with chronic hyperglycaemia, leading to dysregulated inflammatory and angiogenic processes. This condition makes DFUs prone to chronicity and bacterial infection. This study aimed to develop a …

School-aged children a neglected group of research: A systematic review on the sleep patterns, chronotype, latitude and ethnicity

Sandra Figueiredo, Genta Kulari, Ana I. Gomes

Disturbances in daytime and nighttime schedules can significantly impact school-aged children, particularly in relation to their academic performance and cognitive functioning. Several factors may contribute to these challenges, including chronotype characteristics, sociocultural context, and geographical location (latitude) where children live. To our …

Continuous-flow titration of low iron doses to promote photo-Fenton and photo-Fenton-like processes at neutral pH

Carla S. Santos, Miguel Angel Herraiz, Engracia Lacasa, Cristina Sáez et autres

Photo-Fenton (PF) is a promising process for degrading a wide range of contaminants of emerging concern (CECs) present in urban wastewater (UWW) after secondary treatment, mitigating their spread in aquatic systems. However, the near-neutral pH of UWW poses a challenge to PF …
