Abstract
The objective of this study is regeneration of fouled nanofiltration membrane used in dying process of textile industrial wastewater treatment to save its lifetime and therefore conduct the expenses. Chemical treatment method used to regenerate fouled membrane; different concentrations of chemical agents such as sulfuric acid, acetic acid, sodium hydroxide, and EDTA were used at different time and temperature. Three techniques were used to investigate chemical agents influence membrane surface, scanning electron on microscopy (SEM), energy dispersive X-ray (EDX) and Fourier transform infrared spectroscopy FTIR
