Sharpening Nanofiltration: Strategies for Enhanced Membrane Selectivity

ACS Applied Materials & Interfaces, 2020
Nanofiltration plays an increasingly large role in many industrial applications, such as water treatment (e.g., desalination, water softening, and fluoride removal) and resource recovery (e.g., alkaline earth metals).

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 ...

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 ...

Removal of haloacetic acids by nanofiltration

Journal of Environmental Sciences, 2009
Haloacetic acids, disinfection byproducts (DBPs) formed during drinking water chlorination process are carcinogens. The efficacy of nanofiltration (NF) was examined for the removal of five regulated haloacetic acids (HAA5): chloro-, dichloro-, and trichloro-acetic acid (CAA, DCAA, and TCAA); bromo-, and dibromo-acetic acid (BAA, and DBAA) in synthetic ...

Treatment of landfill leachates by nanofiltration

Journal of Environmental Management, 2010
Landfill leachate contains high concentrations of organic matter, color, heavy metals and toxic substances. This study presents the feasibility of a commercial nanofiltration membrane (NF-300) in the removal of pollutants from a landfill leachate generated from the Treatment Stabilization and Disposal Facility in Gujarat state of India.

Performance of nanofiltration for arsenic removal

Water Research, 2002
Performance of rapid sand filtration inter-chlorination system was compared with nanofiltration (NF) to reduce the arsenic health risk of drinking water. It was found that rapid sand filtration with inter-chlorination is not effective in removing arsenic.

Nanofiltration of Dyes

2017
Membrane separation process is perhaps one of the promising alternatives in water treatment over adsorption, being a greener mode of separation. Nanofiltration of dye-contaminated wastewater is a potential and viable membrane separation technology to effectively remove dyes from the water stream.

Coupled ozonation with nanofiltration and catalytic nanofiltration for the removal of micropollutants from secondary effluent

Environmental Science and Pollution Research
Emerging contaminants have become a global concern in recent years. Ozonation is an effective treatment for their degradation. However, it may generate toxic by-products under certain conditions. Catalytic ozonation is an option for improved contaminant oxidation, which can be enhanced by incorporating a filtering membrane, adding the advantages of ...
