1 Nanofiltration is a new separation technique located between reverse osmosis and ultrafiltration. 2 A novel evaluation of the separation performance of nanofiltration (NF) membranes for the mixed electrolytes solution was proposed. 3 Diafiltration desalting process through nanofiltration was analysed in this paper. 4 A composite nanofiltration membrane is fabricated by the interfacial polymerization supported on a microporous polysulfone substrate,[www.] using PDMAEMA as the prepolymer of the crosslinking reaction. 5 Aromatic polyamide nanofiltration membrane is prepared by the solution of aromatic polyamide fiber via immersion precipitation phase inversion process. 6 The concentration characteristics of nanofiltration membrane for treating Gentamicin B solution were presented. 7 In the field of nanofiltration, South Africa's North-West University has built a treatment plant that incorporates ultrafiltration membranes to clean brackish groundwater in a ruralvillage. 8 Reverse osmosis and nanofiltration membranes fouled by humic acid were systematically characterized by transmission electron microscopy. 9 Nanofiltration is a form of filtration that uses membranes to preferentially separate different fluids or ions of nano scale. Its filtering capability is between UF and RO. 10 Surface charge performance of nanofiltration membrane affects the flux, permselectivity and the anti-pollution ability. 11 The separation mechanism of nanofiltration(NF) membrane and its applications in food and pharmaceutical industries are reviewed. 12 Nanofiltration membrane separation technology is the key technology for realization of decomposition at low concentration and crystallization at high concentration. 13 The experimental results showed that nanofiltration membrane NF270 in batch diafiltration operation mode was applicable in desalination and concentration of aqueous dye solution. 14 The performance of polyimide nanofiltration membrane to separate 2 - butanone and oil was investigated. 15 Volatile compounds in tomato juice have been detected by TCT-GC-MS from the concentrate juice using the methods of nanofiltration, freeze concentration, vacuum evaporation and ultrafiltration. 16 The effect of salt concentration on the desalination performance of CA( cellulose acetate ) and PA(polyamide) nanofiltration membranes was studied. 17 Taking the water penetration flux, the conductivity of solution under test before and after nanofiltration, and the concentration of cynarin as indexes in nanofiltration process. 18 During the processing of APT crystallized barren liquor , APT solution was converted into AMT solution by adjusting the pH value, then AMT was treated by nanofiltration. 19 The membrane technologies for liquid separation include microfiltration, ultrafiltration , nanofiltration reverse osmosis and electro-dialysis et al. 20 A study is conducted on separation and recycle of lincomycin from wastewater using nanofiltration membranes. 21 Furthermore, the result also indicated that NF2 membrane suits neither continuous separation of high concentration wastewater nor primary separation unit of nanofiltration system in series. 22 In Egypt, SabryCorp, is working with the Desert Research Institute and the Ministries of Agriculture and Research to commercialise novel nanofiltration systems. 23 Membrane technologies consist of a group of treatment processes which include reverse osmosis, nanofiltration and ultrafiltration. 24 The results show that the electrostatic effect played a major role in nanofiltration by charged membrane. 25 Taking well water as the object, the effect of nanofiltration on removing organics and similar anthrax bacillus contamination was dealt with.
