Titania-acrylic coil reactor for photocatalytic water purification and sterilization / Luke H. Loetscher in Industrial & engineering chemistry research, Vol. 48 N° 10 (Mai 2009) 

Public ISBD [article]  in Industrial & engineering chemistry research > Vol. 48 N° 10 (Mai 2009) . - pp. 4697–4702 Titre : Titania-acrylic coil reactor for photocatalytic water purification and sterilization Type de document : texte imprimé Auteurs : Luke H. Loetscher, Auteur ; Jonathan M. Carey, Auteur ; Stephanie L. Skiles, Auteur Année de publication : 2009 Article en page(s) : pp. 4697–4702 Note générale : Chemical engineering Langues : Anglais (eng) Mots-clés : Titania−acrylic  reactor  CoilCompact  fluorescent  blacklight  Ultraviolet  light  emitting  diodes Résumé : A titania−acrylic composite reactor was constructed with a coil geometry. The presence of multiple titania layers within the reactor increases the titania surface area while making maximum use of the illumination provided. Both compact fluorescent blacklight (CFL) and ultraviolet light emitting diodes (LEDs) were used as illumination sources. An external pump was used to recirculate 650−800 mL of water containing organic, metallic, or bacterial contamination through the coil reactor. Complete purification of the water was achieved within 300 min with 10 ppm methylene blue, 10 ppm methyl orange, 20 ppm Pb2+, and 2200 colony forming units per milliliter (CFU/mL) of E. coli respectively using the CFL source. The effectiveness, low cost, durability, ruggedness, and energy efficiency of this reactor are advantageous for both portable and fixed-base applications.
