Nanofiltration process for treatment of ground water of south of Quchan
Nanofiltration (NF) membranes have
applications in several areas. NF can be used to treat
all kinds of water including ground, surface and/or
used as a pretreatment for desalination. NF
membranes have been shown...
Nanofiltration treatment of tomato paste processing wastewater: Process modeling and optimization using response surface methodology
hydraulic resistance, and COD rejection of tomato wastewater during nanofiltration treatment was investigated. The flux was found to be approximately constant during long period operation. The flux was reduced as the pH declined, while it was increased...
Separation of Sugar from Molasses by Ultrafiltration and Nanofiltration
Molasses, the main material of this project was diluted and processed, according to the type of the
used ultra and nano membranes (UF10kDa, UF5kDa, N30F). Permeate flux was determined at different times for
membranes ...
Preparation of hydrophilic nanofiltration membranes for removal of pharmaceuticals from water
Asymmetric polyethersulfone (PES) nanofiltration membranes were prepared via phase inversion technique. PES
polymer, Brij 58 as surfactant additive, polyvinylpyrrolidone (PVP) as pore former and 1-methyl-2-pyrrolidone (NMP) as solvent were...
Purifying anion exchange resin regeneration effluent using polyamide nanofiltration membrane
fromwaste brine by using polyamide tubular nanofiltration membrane in order to save on both salt andwater consumption for ion-exchange regeneration process. A 77% reduction in salt consumption, a 90% reduction in water consumption and removal value...
Modeling of Arsenic, Chromium and Cadmium Removal by Nanofiltration Process Using Genetic Programming
In this paper, genetic programming (GP) as a novel approach for the explicit formulation of nanofiltration (NF) process performance is presented. The objective of this study is to develop robust models based on experimental data for prediction...
Nanofiltration treatment of waste brine obtained from sugar decolorizing resin regeneration
polyamide tubular nanofiltration membrane in order to saving on both salt and water consumption for ion-exchange regeneration process. The trials display satisfactory qualitative performance for the removal of colorant from the resin regeneration waste...
Effect of hydrophilic/hydrophobic nano silica on the performance of polyvinylchloride nanofiltration membrane
The surface properties of nano particles seems to have a major influence on membrane performance, however this factor has not been studied as much as nanoparticle loading. Here we have prepared polyvinylchloride (PVC) nanofiltration membranes from...
