Quaternary treatments in the upgrading of wastewater treatment plants: micropollutant removal and operation reliability
(Corresponding) Verlicchi P., Grillini V., Galletti A.
Topic:
1. WATER AND WASTEWATER TREATMENT AND REUSE
The recent revised Urban Wastewater Treatment Directive (UWWTD) requires the implementation of quaternary treatments (QT) for large wastewater treatment plants (WWTPs) and for small ones placed in risk areas in order to reduce micropollutants (MPs) content. The current study compares the operation...Read more
The role of methylparaben as an environmental contaminant in enhancing the pathogenicity of drinking water bacteria
(Corresponding) Pereira A., Gomes I., Simões M.
Topic:
1. WATER AND WASTEWATER TREATMENT AND REUSE
Parabens, commonly used as preservatives in personal care products, can affect drinking water (DW) environmental microbial communities, posing an emerging global concern for public health. This study examines the impact of MP at 15 µg/L on the virulence of Acinetobacter calcoaceticus and...Read more
PhotoBioValue project: Linking N:P Ratios and Nitrogen Sources to Microalgae-Based Wastewater Bioremediation and Biomass Valorisation
(Corresponding) Sousa S., Machado C., Esteves A., Salgado E., Dias J., Vilaça J., Pires J.
Topic:
1. WATER AND WASTEWATER TREATMENT AND REUSE
Microalgae-based systems offer potential for wastewater bioremediation by extracting nutrients while producing biomass for various uses. However, variations in wastewater properties, particularly the source of nitrogen and phosphorus, their concentration, and the N:P ratio, impact treatment...Read more
PhotoBioValue project: Microalgae-bacteria consortium for the bioremediation of urban wastewater in pilot-scale photobioreactors
(Corresponding) Salgado E., Ribeirinho-Soares S., Sousa S., Gonçalves A., Ratola N., Pires J.
Topic:
1. WATER AND WASTEWATER TREATMENT AND REUSE
Two innovative pilot-scale channel photobioreactors (PBRs) were used to culture a microalgae-bacteria consortium in primary urban wastewater. The abundance of total heterotrophs and faecal coliforms, and the concentrations of nitrogen, phosphorus and seven volatile methylsiloxanes (VMSs) were...Read more

Metagenomic analysis of urban wastewater resistome and mobilome: Implications for Reclaimed Water Safety in Agriculture.
(Corresponding) Subirats J., Brown L., Marizzi A.
Topic:
1. WATER AND WASTEWATER TREATMENT AND REUSE
The reuse of reclaimed wastewater for agricultural irrigation is a promising solution in regions experiencing water scarcity, yet it raises concerns about the persistence of antibiotic resistance genes (ARGs) and mobile genetic elements (MGEs). This study employed metagenomic analyses to...Read more
Testing adsorption properties of natural zeolites for nutrients in wastewater
(Corresponding) Ravina M., Marotta E., Zanetti M.
Topic:
1. WATER AND WASTEWATER TREATMENT AND REUSE
Low-cost and efficient removal of nutrients in decentralized wastewater treatment plants is still challenging. The installation of supplementary adsorption systems may, in some cases, be appropriate. This work focused on two types of untreated natural zeolites, clinoptilolite and chabasite, with...Read more
Treatment of High-Strength Domestic Wastewater in Anaerobic, Aerobic and Anoxic Fed-Batch Process System
(Corresponding) Rollon A., Lingating R., Pimentel J., Areo H., Ibias K., Mamugay R., Dela Cruz I.
Topic:
1. WATER AND WASTEWATER TREATMENT AND REUSE
For treatment of high-strength domestic wastewater, this study explores a fed-batch bioprocess system consisting of anaerobic (AD), aerobic (AER) and anoxic (ANX) processes in this order and each run at 24 h hydraulic retention time (HRT) and 0.8 g COD/L/d in the first bioreactor. The largest COD...Read more

Topic:
1. WATER AND WASTEWATER TREATMENT AND REUSE
Antibiotics are widely used in healthcare, agriculture, and animal husbandry, contributing to their increased presence in water sources through wastewater, agricultural runoff, and improper disposal. This leads to antibiotic-resistant bacteria and poses risks to both ecosystems and human health...Read more
Application of Cell Immobilization in the Batch Activated Sludge Treatment of Domestic and Poultry Wastewater Using Carbonized Coconut Shell and Carbonized Rice Hull
(Corresponding) Lingating R., Rollon A.
Topic:
1. WATER AND WASTEWATER TREATMENT AND REUSE
Domestic wastewater (DWW) and poultry wastewater (PWW) are some of the primary sources of pollution that affect receiving surface and marine waters, potentially causing eutrophication and other environmental concerns. This study aimed to evaluate the effect of cell immobilization in the performance...Read more
Revalorized Reverse Osmosis Membranes: A Sustainable Solution for Gray Water Treatment
Carrasco A., Cifuentes F., Gonzalez-Perez T., Cabezas R., Merlet G., Rozas-Galvez A., (Corresponding) Pino-Soto L.
Topic:
1. WATER AND WASTEWATER TREATMENT AND REUSE
Water scarcity has intensified global interest in wastewater reuse. Greywater, due to its lower contamination load, is a promising source for non-potable applications. This study evaluates the reuse of end-of-life reverse osmosis (RO) membranes, recovered through chemical cleaning and NaClO...Read more
