Effect of fouling and cleaning upon the surface charge and porosity of polyethersulphone membranes during coffee brew decaffeination
(Elsevier, 22.07.2023)Filtration processes could offer a viable alternative to use of solvents for the production of reduced caffeine coffee beverages (so called ‘half-decaf’) which have recently gained increased commercial attention. However ... -
Effect of Precipitation Temperature on the Properties of Cellulose Ultrafiltration Membranes Prepared via Immersion Precipitation with Ionic Liquid as Solvent
(MDPI, 25.09.2018)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 ... -
End-of-life RO membranes recycling: Reuse as NF membranes by polyelectrolyte layer-by-layer deposition
(Elsevier, 06.05.2019)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 ... -
Microbubble-microplastic interactions in batch air flotation
(Elsevier, 02.07.2022)Presence of microplastics in waste streams and the environment is a challenge of much recent concern. Bubbles are used for solid–liquid separation in froth flotation and dissolved air flotation (DAF). Bubble-particle ... -
Performance enhancement of thin‐film composite membranes in water desalination process by wood sawdust
(Wiley, 18.07.2019)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 ... -
Polyelectrolyte multilayers modification of nanofiltration membranes to improve selective separation of mono- and multivalent cations in seawater brine
(Elsevier, 07.11.2023)Nowadays, 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 ... -
Ultra-desulfurization of sulfur recovery unit wastewater using thin film nanocomposite membrane
(Elsevier, 30.03.2019)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 ...
