This study explores the development and optimization of quartz-based filtration media for industrial oil–water separation, focusing on enhancing surface wettability, minimizing fouling, improving oil rejection efficiency. High-purity quartz particles (SiO2: 98%, Fe2O3: 0.18%, particle size: 0.8–1.8 mm) were evaluated in three configurations: raw, acid-washed, surface-coated with hydrophilic nanoparticles (Al2O3 P2O5). The medium was constructed as a packed-bed rather than continuous sintered membrane, providing cost-effective modular structure separation processes. Comprehensive material characterization performed using X-ray diffraction (XRD), Scanning Electron Microscopy (SEM), Energy Dispersive Spectroscopy (EDS). XRD confirmed crystalline stability across all treatments, while SEM EDS revealed enhanced morphology elemental distribution—especially phosphorus aluminum—in coated samples. Performance testing synthetic oily wastewater (initial concentration: 183,754.8 mg/L) demonstrated that achieved superior reducing residual concentration to 29.3 mg/L, compared 1583.7 mg/L 1859.8 washed raw quartz, respectively. Contact angle analysis improved hydrophilicity media, which also exhibited lower fouling propensity. Taguchi (conducted via Minitab 21.3) regression modeling identified coating operational pressure (optimal at 2.5 bar) most significant parameters influencing rejection. Post-filtration structural integrity durability. Additionally, flux recovery above 90% after backwashing indicated strong regeneration capability. These findings validate surface-modified packed beds robust, scalable, economically viable alternatives conventional membranes treatment. Future research will explore multilayer coatings, long term performance under aggressive conditions, AI-based prediction models.
