Abstract:The separation principles of saline dye solution by nanofiltration membrane,the selection of nanofiltration membrane,the process and application of desalination and concentration by nanofiltration,the application of nanofiltration in the treatment and recycling of dye wastewater,the economic feature of nanofiltration process and membrane fouling control were reviewed.It is concluded that nanofiltration can improve the manufacturing process of dye and help to realize cleaner production,which has significant economic and environmental benefits.During the treatment process,the concentrated solution and permeated solution can be treated separately,which is favorable for better recycling and further treatment of wastewater.The nanofiltration method is an efficient method for the treatment of saline dye wastewater with high concentration.
Keywords:nanofiltration  membrane separation technology  dye  desalination  concentration  wastewater  membrane fouling
