Separation of Concentrated Dye-Salt Solutions by Nanofiltration.
Original language description
Industrial organic dyes are produced with large content of salt. This content is undesirable in many points of view. For removing of the salt from the dye solution we can use membrane nanofiltration. Nanofiltration is the pressure driven membrane, whichcan separate particles with molecular weight above 200 daltons. Thus molecules of organic dye (molecular weight above 1000 daltons) are rejected by the membrane and water with salt can pass through. The aim of this work is to study the separation oof aqueous dye-salt solutions by membrane nanofiltration. Especially, it is to investigate the influence of process conditions (salt and dye concentrations, pressure and temperature) on rejection and flux of commercial nanofiltration membranes and choose suitable mathematical model for separation at high dye concentrations, typical for desalting process.
