Polyelectrolyte multilayers modification of nanofiltration membranes to improve selective separation of mono- and multivalent cations in seawater brine
(Elsevier, 2024-02-05)
Article
Open AccessNowadays, brine produced in the Reverse Osmosis (RO) seawater desalination plants is a significant and largely untapped source of critical minerals and metals, which is usually discharged into the seas as wastewater. As a ... -
X-ray photoelectron spectroscopy (XPS) study of surface oxidation of UO2 doped with Gd2O3 at different temperatures and atmospheres
(2023-08)
Article
Open AccessIn this work, the influence of GdIII doping on the surface oxidation of UO2 has been investigated in situ by XPS. The samples were put in contact with either hydrogen, argon or synthetic air streams saturated with water ... -
Techno-economic analysis of seawater reverse osmosis brines treatment using nanofiltration modelling tools
(Elsevier, 2023-09)
Article
Open AccessThe management of seawater desalination (SWD) brine presents environmental and economic challenges. However, according to the circular economy approach, this residue offers an interesting source of resources. While ... -
Evaluation of the nanofiltration of brines from seawater desalination plants as pre-treatment in a multimineral brine extraction process
(2023-10)
Article
Open AccessMany materials essential to the European Union's (EU) economy lack primary resources, and the major suppliers of these materials are non-EU nations. It has been determined that seawater reverse osmosis (SWRO) desalination ... -
Breaking boundaries in CO2 capture: Ionic liquid-based membrane separation for post-combustion applications
(Elsevier, 2023-09-01)
Article
Open AccessAs a part of global warming reduction strategies, CO2 capture and storage (CCS) is considered a promising and effective method, which can be classified as absorption and adsorption, chemical looping combustion and cryogenic ... -
SbSeI and SbSeBr micro-columnar solar cells by a novel high pressure-based synthesis process
(Royal Society of Chemistry (RSC), 2023-07-17)
Article
Open AccessVan der Waals chalcogenides and chalcohalides have the potential to become the next thin film PV breakthrough, owing to the earth-abundancy and non-toxicity of their components, and their stability, high absorption coefficient ... -
A mathematical model for ammonium removal and recovery from real municipal wastewater using a natural zeolite
(Elsevier, 2023-10-01)
Article
Restricted access - publisher's policyA study was carried out to remove/recover ammonium (NH4+) from residual effluents in tertiary treatment by sorption/desorption processes onto a natural clinoptilolite zeolite (NZ) in batch and fixed-bed column systems. ... -
Ammonium recovery and concentration from synthetic wastewater using a poly(4-methyl-1-pentene) (PMP) liquid–liquid membrane contactor: Flux performance and mass transport characterization
(Elsevier, 2023-12-01)
Article
Restricted access - publisher's policyHollow fiber membrane contactors are a promising technology for the removal and recovery of ammonia from liquid effluents. However, a better understanding of the process engineering (e.g. mass transport of ammonia over ... -
Life-cycle assessment and techno-economic evaluation of the value chain in nutrient recovery from wastewater treatment plants for agricultural application
(Elsevier, 2023-09-20)
Article
Restricted access - publisher's policyThe recovery of nitrogen and phosphorus is important to promote circular economy in wastewater treatment plants (WWTPs). In this study, the life cycle assessment (LCA) and techno-economic assessment (TEA) of a novel ... -
Advanced hybrid system for ammonium valorization as liquid fertilizer from treated urban wastewaters: validation of natural zeolites pretreatment and liquid-liquid membrane contactors at pilot plant scale
(Multidisciplinary Digital Publishing Institute (MDPI), 2023-06-02)
Article
Open AccessThis study evaluates a hybrid system combining zeolites as a sorption stage and a hollow fiber membrane contactor (HFMC) for ammonia (NH3) recovery from treated urban wastewater. Ion exchange with zeolites was selected as ... -
Integrated synthesis, modeling, and assessment (iSMA) of waste-to-resource alternatives towards a circular economy: the case of the chemical recycling of plastic waste management
(Elsevier, 2023-07)
Article
Open AccessThe need to transform economic models to implement a circular use of resources is crucial due to the current waste accumulation crisis. New waste-to-resource alternatives are constantly emerging to close material loops; ... -
Integration of ion exchange resins and membrane technology for purification of boron from seawater desalination brines
(Elsevier BV, 2023-05)
Article
Open AccessBoron is considered a critical raw material (CRM) to the European Union (EU) due to its economic importance and supply risk. To ensure the sustainable supply of boron and other CRMs to EU industry in a circular economy ...
