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.

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

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 ...

Characteristics and Application of Ceramic Nanofiltration Membranes

Annals of the New York Academy of Sciences, 2003
Abstract: In this paper we report on the characteristic and filtration behavior of a newly developed ceramic nanofiltration membrane and compare it with other commercial ceramic nanofiltration membranes currently available. It is shown that it is possible to produce a ceramic membrane with separation properties in the nanofiltration range and with ...

Concentration of Grape Must by Nanofiltration Membranes

Food and Bioproducts Processing, 2003
In this study the selectivity of two nanofiltration (NF) membranes was tested with the aim of increasing the sugar content of grape must used for wine production. The composition of grape must, concentrate, permeate and the rejection values for selected physicochemical parameters is presented.
