Prototype for Removal of Residual Chlorine, Hardness and Manganese from Drinking Water

Silva D., (Corresponding) Hansen E., Rodrigues M., Aquim P.
Topic: 
1. WATER AND WASTEWATER TREATMENT AND REUSE
Residual chlorine, while crucial for water disinfection, can lead to skin irritation and hair degradation over time. Additionally, water hardness exacerbates dermatological conditions such as atopic dermatitis and hair breakage, and elevated manganese concentrations can be toxic, negatively...Read more

Assessment of Tannery-Derived Pollution in the Sinos River Basin, Brazil

(Corresponding) Hansen E., Aquim P., Rodrigues M.
Topic: 
1. WATER AND WASTEWATER TREATMENT AND REUSE
Abstract The leather industry is water-intensive and generates highly polluted wastewater. Brazil, with the world’s largest commercial cattle herd, is a leading leather producer. The state of Rio Grande do Sul holds a prominent position in national exports, with a high concentration of tanneries in...Read more

Membrane-Based Treatment of Hydrothermal Carbonization Effluent from Municipal Biowaste

Mendes V., Faria A., Miguel C., (Corresponding) Esteves B.
Topic: 
1. WATER AND WASTEWATER TREATMENT AND REUSE
The treatment of hydrothermal carbonization (HTC) liquor derived from municipal solid waste (MSW) remains a key challenge due to its high organic load. This work compares, for the first time, the direct application of polymeric microfiltration (MF) and ultrafiltration (UF) with a multi-stage...Read more

New Insight on Homolytic Peroxodisulfate Activation by Iron Sulfides and FeIV=O2+ Formation

(Corresponding) Guo P., Sühnholz S., Mackenzie K.
Topic: 
1. WATER AND WASTEWATER TREATMENT AND REUSE
The aim of this study is to further investigate the mechanism of peroxodisulfate (PS) activation by iron sulfide crystals (FeSx) in the surface-mediated process in the aqueous environment. Various iron sulfide crystals were synthesized through co-precipitation and etch coating methods and screened...Read more

Microalgae cultivation in ammonia rich digestate subjected to different pretreatment stages

Palikrousis T., Manolis C., Kalamaras S., (Corresponding) Samaras P.
Topic: 
1. WATER AND WASTEWATER TREATMENT AND REUSE
Anaerobic digestion has been beneficial for the energy valorization of a broad variety of residues. However, the effluent from the digesters, the digestate, usually has high ammonia nitrogen, requiring additional measures for its management. Photosynthetic microalgae assimilate nitrogen, and can be...Read more

Enhancing electro-Fenton-based tertiary treatment for tannery effluent via Response Surface Methodology

Pasciucco E., Pasciucco F., Iannelli r., (Corresponding) Pecorini I., Panico A.
Topic: 
1. WATER AND WASTEWATER TREATMENT AND REUSE
This study focuses on improving advanced oxidation methods as a final treatment for tannery wastewater. The goal was to find the best conditions for an electrochemical peroxidation (ECP) process that removes COD and color from tannery effluents at neutral pH, while reducing costs by avoiding...Read more

CuO nanoparticles as modifiers for membranes for anaerobic membrane digestion

(Corresponding) Papadopoulou K., Pavlopoulos C., Markouli P., Anton D., Lyberatos G.
Topic: 
1. WATER AND WASTEWATER TREATMENT AND REUSE
Membrane separation technologies offer a promising solution for anaerobic digestate treatment but are limited by membrane fouling and reduced flux. This study investigated the use of CuO nanoparticles (NPs) on ultrafiltration membranes to mitigate fouling and improve separation performance during...Read more

Treating PAHs in Scrubber Washwater: an Investigation into Fenton-like Advanced Oxidation

(Corresponding) Bautista-Chamizo E., Bermudez-García L., Cavilla-Molina M., Nebot E., Moreno-Andrés J.
Topic: 
1. WATER AND WASTEWATER TREATMENT AND REUSE
The maritime transport sector primarily uses fuel oil, leading to exhaust gas emissions that contain harmful substances like heavy metals and polycyclic aromatic hydrocarbons (PAHs), which pose risks to marine ecosystems. Exhaust Gas Cleaning Systems (scrubbers) are essential for complying with...Read more

A Novel Automated Water Pretreatment System for Microbial Preconcentration and DNA Extraction Using Monolithic Adsorption Filtration (MAF)

(Corresponding) Moyseos M., Demosthenous P., Seidel M.
Topic: 
1. WATER AND WASTEWATER TREATMENT AND REUSE
Nowadays, there is an urgent need for rapid and efficient microbial monitoring in water resources. This need has become especially critical due to new EU directives mandating zero pathogen presence in drinking and reuse water. This work introduces an innovative, automated pretreatment system that...Read more
