Abstract

The industrial advancement in the textile industry has caused negative environmental impacts because of the large amount of dye wastewater effluent. The treatment of dye wastewater can be conducted using adsorption, biological treatment, and flocculation-coagulation processes. However, all of these methods involve chemical additions, which may increase the operational cost of the wastewater treatment process. To overcome this problem, membrane separation technique has been widely used to treat textile dye wastewater. Cellulose acetate-based membranes in particular are attractive because they have a relatively high percentage for dye rejection. However, the flux still needs to be improved as the volumetric flow rate from textile industries is very high. In recent years, the incorporation of inorganic fillers inside polymer matrix inside mixed matrix membranes (MMMs) attracts many researchers to investigate their potential for gas and water treatment. This research studied the synthesis of cellulose acetate-based MMMs to treat methylene blue, a cationic dye commonly found in textile wastewater. ZIF-8 and TiO2 were investigated as inorganic fillers for the MMMs. From the experiments, it was found that ZIF-8 exhibited better dispersion and improved dye rejection than TiO2 particles in the cellulose matrix. However, hydrophilic TiO2-containing MMMs could produce flux as high as 260 LMH, which was higher than pure polymeric membranes and ZIF-8-based MMMs.
