ABSTRACT Membrane technology is increasingly becoming a solution in wastewater treatment from textiles and dyeing, however, it has continuing challenge on membrane fouling. In this study, we developed series of hybrid activated clay (AC)/hydroxyapatite (HA)‐polyvinyl alcohol (PVA) composite membranes for fouling control during the removal methylene blue (MB) dye simulated wastewater. AC HA, known their dye‐sorption capabilities, were prepared various ratios incorporated as fillers PVA to form (PVA/AC/HA). Various characterization techniques including Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM) with energy dispersive x‐ray (EDX), zeta potential (ZP), diffraction (XRD) used analyze structure, morphology crystallinity membranes. The integration HA significantly influenced filtration performance, antifouling properties hydrophilic nature Results indicated that 2:1 (AC: HA) ratio was most effective MB removal. This demonstrated optimal porosity pure water flux (PWF) 34.4% 70.3 L/m 2 /h, respectively. Furthermore, achieved peak rejection rate 95.5% exhibited highest recovery 83.9%, highlighting its superior performance.
