Abstract
A nanofiltration membrane has been developed by UV-photografting. Sodium p-styrene sulfonate was used for
the modification of a polysulfone ultrafiltration membrane. The membrane cut-off was estimated. The grafted
membranes have been evaluated for the removal of five different dyes with an aim to reuse water in the process
house. The effect of different parameters such as dye class, pH and the presence of salt was evaluated. It is observed
that the newly developed membranes show acceptable performance both in terms of flux and rejection. Dye retention
was higher than 97% and hydraulic permeability 0.23-0.28 m3.m-?.d-’ at 0.4 MPa. The influence of pH on the
performance of membranes in terms of fouling and retention was established and compared to a commercial membrane
(Desal SDK).
