Development of nanofiltration PES membranes incorporated with hydrophilic para hydroxybenzoate alumoxane filler for high flux and antifouling property

摘要: Abstract The PES nanofiltration membranes incorporated with hydrophilic para hydroxybenzoate alumoxane (PHBA) filler were prepared enhanced pure water flux, dye removal, and antifouling property. fabricated characterized in terms of average pore radius, porosity, surface roughness, contact angle, active layer thickness, zeta potential. roughness the decreased hydrophilicity increased increase PHBA content. According to experiments, highest flux reached up 80.47 kg/m2h under operation pressure 0.4 MPa, which was nearly 5.8 times as much that neat membrane. also exhibited excellent performance removal capability. In best content P-PHBA 0.3 % membrane, rejection 99.21 98.53% achieved for DR 16 MB, respectively. Furthermore, good long-term operational pH stability rejection. membrane recovery ratio (98.50%) lowest irreversible fouling ration (1.50%). Moreover, dominant mechanism determined using Hermia–"s model. This superior behavior relatively high combined remarkable show potential organic-inorganic fillers embedded sustainable treatment technology.
