Concentration and Desalination of Aqueous Dye Solution by Nanofiltration

摘要

Concentration and desalination of NT whitenner solutions by nanofiltration are studied experimentally. By analyzing concentration polarization of NaCl at the membrane- solution interface, simple equations are constructed that is fit for description of concentration and desalination of the dye solutions with spiral wound nanofiltration membrane modules. Several operations were compared which resulting in an optimized technology.
