Reactive azo dyes are present in textile effluents due to their stable nature and extensive use. The removal of reactive azo dyes is required before discharge due to negative environmental and health effects. Common methods of removal include biodegradation through bacteria or fungi, chemical precipitation, or filtration using membrane technologies. Enhanced ultrafiltration is an alternative membrane technology to retain charged pollutants with a membrane of the same charge. This study performed preliminary research focusing on the retention of negatively charged reactive azo dyes through the use of a negatively charged membrane. A low ionic strength solution promoted retention of the dye allowing colorless water to pass through for the application of further purification and reuse.
