Abstract

In this study, the removal of dyes, sulfide, and some other components in batik wastewater using a nanofiltration (NF) membrane was investigated. Remazol red (RR dye), indigosol brown (IB dye), and sodium sulfide (Na2S) were used as models of synthetic batik wastewater. Furthermore, NF performance for treating real batik wastewater was also examined. The effects of operating conditions on flux and rejection were investigated. The results showed that all filtration had similar permeate flux behavior, where rapid flux decline was observed at the initial filtration, followed by gradual flux decrease and then reaching a stable flux. The rejections of the pollutant model during NF of synthetic wastewater were 61–76%, 90–95%, and 90–99% for sulfide, IB, and RR, respectively. The color rejection in real batik wastewater was 99.84%. Further, the removal of chemical oxygen demand (COD) reached 87.6%.
