Research progress of hollow fiber nanofiltration membranes in the dye separation applications
A large amount of high salinity wastewater rich in dyes is produced in the printing and dyeing industry. Benefiting from the selective separating property，hollow fiber nanofiltration（NF） membranes are expected to achieve the efficient separation of dyes and inorganic salts，which can complete the pollution control of printing and dyeing wastewater as well as the synchronous recovery of valuable resources. Compared to the conventional spiral-wound NF membrane，hollow fiber NF membrane also presents advantages including high packing density and self-supporting ability. Therefore，it has received increasing attention in the field of printing and dyeing wastewater treatment. The recent research progress of hollow fiber NF technology in the dye separation process were reviewed. Specifically，the preparation of loose hollow fiber NF membrane and positively charged hollow fiber NF membrane suitable for dye separation were discussed. The membrane fouling characteristics of hollow fiber nanofiltration membrane in dye separation process and the corresponding membrane fouling control measures were analyzed. Finally，the future research directions were prospected to further promote the application of hollow fiber nanofiltration membrane technology in dye wastewater treatment.
