Abstract
The possibility of using nanofiltration as a treatment method for waste water in the textile industry was investigated. An effluent from a textile factory, after biological treatment and sand filtration, was taken as feed solution for a lab-scale nanoflltration unit. The retention of organic and inorganic compounds was tested for three nanoflltration membranes: NF70 (FilmTec), Nitto NTR 7450 (Nitto-Denko) and UTC-20 (Toray). As expected, considerable differences in retention were observed. The highest retentions were obtained for NF70. For UTC-20 and Nitto 7450, retentions were slightly lower. Colour removal was nearly complete for the three membranes.
