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

Factors Influencing Particulate Matter Variability in an Urban Street in Chios

(Corresponding) Kotrikla A., Salaveri S., Maroulis C.

Topic:

7. ENVIRONMENTAL POLLUTION

This study examines how traffic flow, suburban PM2.5 concentrations, noise and meteorological factors influence particulate matter levels in an urban street. Spearman’s correlation analysis reveals that urban PM10 concentrations are moderately and significantly correlated with traffic flow (ρ=0.574...Read more

Biochar derived from the invasive aquatic plant Myriophyllum spicatum: Characterization via SEM–EDX and application in lead removal

(Corresponding) Milojković J., Wurzer C., Lopičić Z., Šoštarić T., Koprivica M., Vuković N., Masek O.

Topic:

1. WATER AND WASTEWATER TREATMENT AND REUSE

The accumulation of lead (Pb) in aquatic environments remains a significant environmental challenge due to its toxicity and persistence. Meanwhile, invasive aquatic plants, such as Myriophyllum spicatum, cause ecological and economic issues due to their rapid growth and extensive biomass production...Read more

Ultrasound Treatment of Digested Sludge: a dual approach for Energy Recovery and Emerging Contaminant Reduction

(Corresponding) Ciotola E., Esposito G., Pirozzi F., Cesaro A.

Topic:

2. CIRCULAR ECONOMY AND BIOECONOMY

Digested sludge (DS) is a valuable matrix that still holds potential for energy and nutrient recovery. This study explored the application of low-frequency ultrasound (US) treatment of DS to enhance organic matter solubilization and Polycyclic Aromatic Hydrocarbons (PAHs) transfer while reducing...Read more
