Abstract
Metaloxidesnanoparticlesareofpotentialinterestforpressure-drivenmembranesinviewofflux increaseandreducedfoulingresistance.Inthisstudy,polyethersulfone(PES)flat-sheetmembranes were manufacturedbythephaseinversionmethodforwastewatertreatmentapplication.APES membranewasmodifiedbydispersingnanoparticlesofTiO2, Al2 O3 and ZrO2 in aPESsolution. Nanoparticlessizedistributionwascharacterizedbyscanningelectronmicroscope(SEM)anddynamic light scattering(DLS)methodtoexploretheeffectofnanoparticleaggregation.Furthermore, membraneswerecharacterizedbyhydrophilicity(contactangle),morphology(SEM),porosity,and thermalanalysis(TGA).MembranefoulingwasstudiedwithBSAandhumicacidsasmodelorganic foulants.Entrappedmetaloxideschangedthemembranemorphologytomoreopenandporous structureandtheantifoulingpropertyandlongtermfluxstabilityofmetaloxidemodifiedmembranes were significantlyenhanced.Strongcorrelationswereobservedbetweensomephysico-chemical propertiessuchas,porosity,hydrophilicityandpermeabilityofmodifiedmembraneswiththespatial particle distributioninthemembranestructure.Thefoulingresistanceofmodifiedmembraneswas significantlyreduced,showingthattheparticledistributionisakeyparameterforthemembrane foulingreduction.Therejectionpotentialofnewmembraneswashardlyaffected.
