Removal of haloacetic acids by nanofiltration
Journal of Environmental Sciences, 2009Haloacetic 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 ...

Performance of nanofiltration for arsenic removal
Water Research, 2002Performance 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.

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.

Identification of nanofiltration membrane foulants
Water Research, 2007The 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 ...

Nanopapers for organic solvent nanofiltration [PDF]
American Chemical Society. Abstracts of Papers (at the National Meeting), 2014 Would it not be nice to have an organic solvent nanofiltration membrane made from renewable resources that can be manufactured as simply as producing paper? Here the production of nanofiltration membranes made from nanocellulose by applying a papermaking

A review concerning membrane bioreactor (MBR) types and MBR in which nanofiltration sepn. is used, including a further distinction made between cell- and enzyme-based processes, is given. Topics discussed include: reactor types; membrane fermentors (prodn. formation, wastewater treatment, engineering); enzyme reactors (oxidn./redn.

According to Koros et al. [1] fouling is “the process resulting in loss of performance of a membrane due to deposition of suspended or dissolved substances on its external surfaces, at its pore openings, or within its pores”. Fouling is also decribed as flux decline which is irreversible and can only be removed by, for example, chemical cleaning [2 ...
