Drinking water treatment in a gravimetric flow system with TiO2 coated membranes / Rosangela Bergamasco in Chemical engineering journal, Vol. 174 N° 1 (Octobre 2011)  

Public ISBD [article]  inChemical engineering journal > Vol. 174 N° 1 (Octobre 2011) . - pp.102-109 Titre : Drinking water treatment in a gravimetric flow system with TiO2 coated membranes Type de document : texte imprimé Auteurs : Rosangela Bergamasco, Auteur ; Flávia Vieira Silva, Auteur ; Flávia Sayuri Arakawa, Auteur Année de publication : 2012 Article en page(s) : pp.102-109 Note générale : Génie chimique Langues : Anglais (eng) Mots-clés : Drinking water Membrane modification TiO2 film fouling Résumé : This paper presents filtration results for drinkingwatertreatment obtained with a commercial cellulose acetate membrane of 0.45 μm pore diameter, with and without TiO2 coating. The deposition of titanium dioxide thin films onto membrane surface was made by pulsed-frequency d.c. reactive magnetron sputtering at room temperature from a high purity Ti target in Ar/O2/N2 atmosphere, at different conditions for cathode current and for deposition time. The proposed membranes were used in a filtration system driven by gravitation without the requirement of energy supply. The obtained results showed that the proposed system is able to remove color and turbidity from raw water. Besides, the modified membrane presented better results than the neat one regarding to membrane fouling and chlorine removal.
