Polymer-based nanofiltration membranes

2022
The demand for advanced water treatment technologies is continuously increasing due to clean water scarcity, strict environmental regulations, growing population, and increasing discharges of industrial wastewater. Polymer-based nanofiltration (NF) membranes are of particular interest due to their low cost and high removal efficiency for multivalent ...

Identification of nanofiltration membrane foulants

Water Research, 2007
The Mery-sur-Oise plant (France) has been using nanofiltration (NF) membranes (NF200) to produce safe drinking water since 1999. However, significant fouling has been occasionally observed according to seasonal conditions, even with various pre-treatments including conventional surface water treatment followed by ozonation, acid addition to pH 6.9 ...

Electroviscous Effects in Ceramic Nanofiltration Membranes

ChemPhysChem, 2015
AbstractMembrane permeability and salt rejection of a γ‐alumina nanofiltration membrane were studied and modeled for different salt solutions. Salt rejection was predicted by using the Donnan‐steric pore model, in which the extended Nernst–Planck equation was applied to predict ion transport through the pores.

Hafnia ceramic nanofiltration membranes

Journal of Membrane Science, 2000
Abstract We use the hindered transport theory for neutral solutes and the macroscopic homogeneous electro-transport theory for ions to predict without any adjustable parameters the limiting rejection of, respectively, four neutral molecules and five binary electrolytes by granular porous hafnia nanofilters.

Polymer Nanocomposite Membranes for Antifouling Nanofiltration

Recent Patents on Nanotechnology, 2016
Fouling refers to the unwanted and undesirable attachment of biological macromolecules, inorganic, organic matter, and microorganisms on water contact surfaces. Fouling reduces the performance of devices involving these submerged surfaces and is considered the bottle-neck issue for various applications in the biomedical industry, food processing, and ...

Physico‐Chemical Characterization of Nanofiltration Membranes

ChemPhysChem, 2007
AbstractThis study presents a methodology for an in‐depth characterization of six representative commercial nanofiltration membranes. Laboratory‐made polyethersulfone membranes are included for reference. Besides the physical characterization [molecular weight cut‐off (MWCO), surface charge, roughness and hydrophobicity], the membranes are also studied

Organic solvent nanofiltration with Grignard functionalised ceramic nanofiltration membranes

Journal of Membrane Science, 2014
Abstract In this paper the use of functionalised ceramic nanofiltration membranes in solvent filtration is described. The membranes were grafted using a novel method for surface modification based on Grignard chemistry. Commercially available 1 nm TiO 2 membranes were differently functionalised with a series of alkyl groups (methyl, pentyl, octyl ...
