Performance optimization and fouling study of geopolymer-zeolite composite membranes for sustainable textile wastewater treatment.

ABSTRACT: This research introduced a cost-efficient and eco-friendly sustainable geopolymer-zeolite composite membrane produced using a non-hydrothermal technique optimized for treating textile wastewater. A new geopolymer-zeolite composite membrane for microfiltration (macroporosity) was generated by activating metakaolin with sodium hydroxide and silica fume. The design of the experiment methodology (full factorial and response surface methodology) was used to identify the most effective parameters and optimize membrane separation performance. The optimum membrane showed the maximum normalized permeability and turbidity reduction of 0.57 and 97.98%, respectively, at 1.2 bar pressure, 59.6 ^°C feed temperature, and 1.73 L/min. Fouling analysis utilizing resistance-in-series indicated that
