On the Fenton oxidation of polystyrene microplastics
(Corresponding) Munoz M., Ortiz D., Nieto-Sandoval J., Romera-Castillo C., de Pedro Z., Casas J.
Topic:
Microplastics in water treatment: fate, toxicity assessment and removal technologies
This work aims at evaluating the fate of polystyrene (PS) microplastics along Fenton oxidation. Experiments were carried out under relatively severe operating conditions (80 ºC) given the high persistence of these solids to oxidation. Slight mass losses (up to 10%) were found after the Fenton...Read more

Continuous flow hydrodechlorination for micropollutants removal using an innovative Pd-based Catalytic Membrane Reactor
(Corresponding) Nieto-Sandoval J., Gomez-Herrero E., Munoz M., de Pedro Z., Casas J.
Topic:
Water treatment
The aim of this work is to develop a Pd-based Catalytic Membrane Reactor (Pd/CMR) for its application in organochlorinated micropollutants removal by hydrodechlorination (HDC). The external surface of a Al2O3 membrane was homogeneously decorated by Pd nanoparticles (0.2% wt.). The Pd/CMR developed...Read more
Application of catalytic hydrodehalogenation for the removal of brominated flame retardants
Nieto-Sandoval J., (Corresponding) Benito del Olmo R., Munoz M., De Pedro Z., Casas J.
Topic:
Water treatment
The aim of this work is to evaluate the feasibility of aqueous-phase catalytic hydrodehalogenation (HDH) for the fast and environmentally-friendly degradation of the flame retardant tetrabromobisphenol A (TBBPA). TBBPA is a pollutant of emerging concern characterized by a strong persistence that...Read more
Magnetite-decorated catalytic membrane reactor for the continuous-flow CWPO of micropollutants
(Corresponding) López-Aragó N., Nieto-Sandoval J., Munoz M., de Pedro Z., Casas J.
Topic:
Advanced oxidation processes
This work aims at developing a contactor type Catalytic Membrane Reactor (CMR) for its application in the continuous removal of micropollutants by Catalytic Wet Peroxide Oxidation (CWPO). For such goal, a porous alumina membrane tube was homogeneously decorated with magnetite nanoparticles...Read more

Nanoplastics mineralization by the intensified photo-Fenton process
(Corresponding) Ortiz D., Munoz M., Carbajo J., M. de Pedro Z., Casas J.
Topic:
Microplastics in water treatment: fate, toxicity assessment and removal technologies
The widespread presence of microplastics (MPs) and nanoplastics (NPs) in aquatic systems has become one of the most challenging environmental issues nowadays. Although advanced oxidation processes (AOPs) have been widely studied for the treatment of persistent contaminants in water, their...Read more

PFAS removal performance of novel technologies for treatment of firefighting water and groundwater
(Corresponding) Hjort M., Dalmijn J., Roest K., ter Laak T., Vaiopoulou E.
Topic:
Soil and groundwater contamination and remediation
Per- and polyfluoroalkyl substances (PFAS) are a group of widely used man-made organic chemical substances. PFAS have been used because of their particular physicochemical properties: most are stable at high temperatures, recalcitrant to chemical oxidation and biological degradation, and act as a...Read more
Properties of dry hydraulic road binder mixture with additional component of cement bypass dust
(Corresponding) Stevulova N., Junak J., Strigac J., Terpakova E.
Topic:
Solid waste management
This paper is aimed at properties characterization of a designed binder mixture containing cement, fine natural limestone, cement bypass dust (BPD), and ground granulated blast furnace slag (GGBS) with an emphasis on a potential utilization of BPD into a normal hardening hydraulic road binder in...Read more
Energy recovery from urea in decentralised wastewater streams
Asiain-Mira R., Zamora P., Rogalla F., Monsalvo V., (Corresponding) Torrente-Murciano L.
Topic:
Water, energy and/or food nexus
This work presents the design of a new process that enables energy recovery from wastewater, based on the selective adsorption of urea from urine and its subsequent decomposition into hydrogen.
Removal of nitrogen compounds is at the core of wastewater treatment, as their uncontrolled discharge...Read more
Keywords:
Wastewater valorisation, energy recovery, urea, adsorption, circular economy.
Investigating the impact of landfill leachates in groundwater quality through the monitoring of multiclass emerging contaminants by LC-HRMS
(Corresponding) Nika M., Gkotsis G., Vasilatos K., Gkogkou A., Stasinakis A., Thomaidis N.
Topic:
Emerging pollutants
Due to their economic advantages, landfills are the primary repository of municipal solid wastes, receiving everyday by-products such as food wastes, plastic containers and product packaging materials, unused pharmaceuticals, textile and other products. As a result of the higher demand and better...Read more

Low temperature conversion of methanol to higher hydrocarbons and hydrogen using a non-thermal plasma
(Corresponding) Dahiru U., Zhang K., Harvey A.
Topic:
Environmental odour, monitoring and control
In recent years, the emission of volatile organic compounds (VOCs) from chemical manufacturing plants, agricultural practises, and indoor sources has attracted public concern, as these emissions have a negative effect on both human health and the environment. VOCs are precursor for the formation of...Read more
