Abstract
Composite nanofiltration membrane was applied to treat chromaticity and chemical oxygen demand (COD) from printing and dyeing wastewater. The results showed that nanofiltration membrane technology could effectively remove the chromaticity and chemical oxygen demand in the printing and dyeing wastewater, and the average removal rates were 100 and 98 %, respectively. Meanwhile, the process of recovery was up to 90 %. The water flux of the membrane was increased with the feed flow rate and the operating pressure and then decreased with the improvement of the process of recovery.
