The Smart Hydrogels for the Controllable Adsorption and Desorption of PFAS
Zhang H., Zalaria J., (Corresponding) Georgi A.
Topic:
1. WATER AND WASTEWATER TREATMENT AND REUSE
In order to address the regeneration issue of adsorbents for the elimination of per- and polyfluoroalkyl substances (PFAS), this work synthesized a novel smart hydrogel based on a temperature-responsive polymer, poly(N-isopropylacrylamide) (PNIPAm). These hydrogels exhibit hydrophobicity and...Read more
Optimizing Plasma Bubbles at Pilot Scale for Organic Pollutant Degradation in Water
Meropoulis S., (Corresponding) Aggelopoulos C.
Topic:
1. WATER AND WASTEWATER TREATMENT AND REUSE
This study investigates the scalability of nanopulsed plasma bubble technology for water remediation, transitioning from lab to pilot scale. The pilot-scale plasma bubble reactor was optimized to degrade toxic organic pollutants, including dyes (methylene blue, MB), antibiotics (sulfamethoxazole,...Read more

Hydrogen Generation from Wastewater-Derived Organics via Solar Photocatalysis Using Low-Cost Cu-TiO₂ Composites
(Corresponding) Clarizia L.
Topic:
1. WATER AND WASTEWATER TREATMENT AND REUSE
Recent research has focused on developing Cu-based TiO₂ photocatalysts for sustainable hydrogen production via solar photoreforming of organic compounds typically present in urban and industrial wastewater. Copper, either in solution or integrated into TiO₂, forms heterojunctions that enhance...Read more
Performance Of Preoxidation And Coagulation In Arsenic Removal From Groundwater For Human Consumption In A Small Rural Community In Western Romania
(Corresponding) Pacala A., Neidoni D., Negrea S., Tenea A., Dinu C., Stefanescu M.
Topic:
1. WATER AND WASTEWATER TREATMENT AND REUSE
Health problems caused by high arsenic concentrations (over 200 μg/L) in groundwater sources in the Pannonian Basin (Hungary, Romania, Croatia, Serbia) have become a major concern for researchers and environmental experts. This paper evaluates the effect of the preoxidation (with hypochlorite)/...Read more
Removal of organic micropollutants by quaternary treatments controlled by optical sensors
Marino L., Gagliano E., Santoro D., Roccaro P.
Topic:
1. WATER AND WASTEWATER TREATMENT AND REUSE
Advanced oxidation processes (AOPs) are widely applied to degrade persistent organic pollutants. In view of new stringent regulations on organic micropollutants, the real-time monitoring of AOPs became crucial to fulfil the high quality standards over time. A fluorescence sensor was employed to...Read more
Adsorption of Ciprofloxacin by Sugarcane Bagasse Activated Biochar in Aqueous Solution
(Corresponding) Ubiña L., Guia R., Aquino C., Somera L., Balela M., Beltran A., Cornista J., Bautista-Patacsil L.
Topic:
1. WATER AND WASTEWATER TREATMENT AND REUSE
Antibiotics such as ciprofloxacin (CIP) in wastewater pose a significant and pressing concern as an emerging contaminant. Conventional wastewater treatments are not optimized to effectively remove antibiotics, resulting in their persistence in bodies of water and significantly contributing to a...Read more

Investigation of waste-derived adsorbents for removal of NORM and non-regulated elements from mining wastewater
(Corresponding) Avsar D., Pelkonen M., Gajendra N., Grønvold R., Angyus B., Dinis M., Vila M., Yilmaz D., Senila M., Ferrando-Climent L.
Topic:
1. WATER AND WASTEWATER TREATMENT AND REUSE
The growing demand for rare earth elements (REEs) has led to an increase in mining activities, raising significant environmental concerns, particularly related to wastewater (WW) management. Mining WW can contain a complex mixture of contaminants, including naturally occurring radioactive materials...Read more
Optimizing biological consortia for mining wastewater treatment
(Corresponding) Gajendra N., (Corresponding) Török A., Avsar D., Pelkonen M., Grønvold R., Dinis M., Vila M., Yilmaz D., Levei E., Ferrando-Climent L.
Topic:
1. WATER AND WASTEWATER TREATMENT AND REUSE
Industrial processes, such as the mineral extraction of raw materials, have been in crucial focus because of the current drive towards greener and more sustainable energy sources. Hence, the production workflow of critical elements, such as rare earth elements (REEs), is reassessed to identify less...Read more

Development of 3D-Printed Permeable Reactive Barrier Adsorbents Utilizing Zeolite Composites for Copper (II) Removal in Acid Mine Drainage
Atega M., Detras M., Eusebio R., Borines M., Maalihan R., (Corresponding) Bautista-Patacsil L.
Topic:
1. WATER AND WASTEWATER TREATMENT AND REUSE
Zeolite-based ceramic structures was fabricated using a viscous solution 3D printing (3DP) technique to demonstrate their effectiveness in removing heavy metal ions from acid mine drainage (AMD) runoff. Zeolite, a low-cost hydrated aluminosilicate clay, is widely used in water treatment due to its...Read more

Exploring the applicability of differential absorbance to simultaneously quantify and control microbial inactivation and DBPs formation
Baccini L., Vagliasindi F., Korshin G., (Corresponding) Roccaro P.
Topic:
1. WATER AND WASTEWATER TREATMENT AND REUSE
Chlorination is effective in inactivating microorganisms. However, its interaction with natural organic matter (NOM) and inorganic ions leads to the formation of disinfection byproducts (DBPs). Surrogate parameters, such as the differential absorbance at 272 nm (DA272), have shown potential for...Read more
