A Reviewof the Hollow Fiber Membranes and TheirApplications for the Removal of Dyes from Dyeing Wastewater

With the development of technology, wastewater from industrial processes is a serious threat to the environment. Due to environmental hazardous of dyeing wastewater, membrane separation method is considered. These days, the membrane technology is highly considered because of its benefits. Since the one of the most important applications in the field of membrane is Filtration. As a result, the membrane can be used in textile wastewater treatment by using of filtration processes (micro, ultra and nanofiltration) which is used in the field of dye removal. Hollow fiber membranes are further considered among their high surface to volume ratio in the field of filtration. These membranes are efficient in fluid separation include gas, wastewater treatment and textile industries. In this article first, types of membrane and its production methods are studied, and then their application in dye removal from textile wastewater is considered.
