Effect of Precipitation Temperature on the Properties of Cellulose Ultrafiltration Membranes Prepared via Immersion Precipitation with Ionic Liquid as Solvent
(MDPI, 2018-09-25)
Supported cellulose ultrafiltration membranes are cast from a cellulose-ionic liquid solution by the immersion precipitation technique. The effects of coagulation bath temperature and polymer concentration in the casting ...
Transport of pharmaceuticals during electrodialysis treatment of wastewater
(Elsevier, 2019-06-13)
Electrodialysis (ED) is a promising emerging electrochemical membrane technology for nutrient concentration and recovery from wastewater. However associated environmental safety aspects have to be assessed before utilizing ...
Ultra-desulfurization of sulfur recovery unit wastewater using thin film nanocomposite membrane
(Elsevier, 2019-03-30)
Herein, to meet the requirement of the stringent sulfur emission and discharge rate standards based on World Health Organization (WHO) and Environmental Protection Agency (EPA), polyamide/titanium dioxide (PA/TiO2) thin ...
End-of-life RO membranes recycling: Reuse as NF membranes by polyelectrolyte layer-by-layer deposition
(Elsevier, 2019-05-06)
Nowadays, end-of-life (EoL) reverse osmosis (RO) membranes are considered as waste, hence they are incinerated or discarded in landfills. Due to the environmental problem of disposed membranes, their reuse as nanofiltration ...
The interplay role of vanillin, water, and coagulation bath temperature on formation of antifouling polyethersulfone (PES) membranes: Application in wood extract treatment
(Elsevier, 2019-10-21)
In this study vanillin was tested as the hydrophilicity promoter in a PES membranes to improve the feasibility of the membranes in the treatment of a biorefinery stream, namely a pressurized hot water extract (PHWE). The ...
Performance enhancement of thin‐film composite membranes in water desalination process by wood sawdust
(Wiley, 2019-07-18)
In this study, polysulfone/wood sawdust (PSf/WSD) mixed matrix membrane (MMM) was prepared as a novel substrate layer of thin‐film composite (TFC) membrane in water desalination. The main aim was to evaluate how different ...
Membrane Filtration Enhanced Hydrometallurgical Recovery Process of Indium from Waste LCD Panels
(Springer Nature, 2020-10-02)
Insufficient recycling of a continuously increasing amount of liquid crystal display (LCD) waste leads to the waste of potentially recyclable materials, especially rare and critical indium. Moreover, landfilling of LCD ...
Cellulose Membranes in the Treatment of Spent Deep Eutectic Solvent Used in the Recovery of Lignin from Lignocellulosic Biomass
(MDPI, 2022-01-13)
Ultrafiltration was employed in the purification of spent Deep Eutectic Solvent (DES, a mixture of choline chloride and lactic acid, 1:10, respectively) used in the extraction of lignin from lignocellulosic biomass. The ...
Preparation of cellulose-rich membranes from wood: effect of wood pretreatment process on membrane performance
(Springer Nature, 2020-09-14)
In this study cellulose-rich membranes were fabricated from untreated and treated hardwood biomass solutions in 1-ethyl-3-methylimidazolium acetate ([Emim][OAc])—dimetylsulfoxide (DMSO) system via wet phase separation. ...
Characterization of membrane–foulant interactions with novel combination of Raman spectroscopy, surface plasmon resonance and molecular dynamics simulation
(Elsevier, 2018-05-23)
Adsorptive fouling, by phenolic compounds, is a serious issue regarding the development and use of membrane based filtration technologies for water purification and wastewater treatment. We have developed a novel, combined, ...
