This book was released on 1993 with total page 118 pages. Available in PDF, EPUB and Kindle. Book excerpt: LA MODELISATION DE L'ADSORPTION SUR CHARBON ACTIF EN REGIME DYNAMIQUE FAIT L'OBJET DE NOMBREUX TRAVAUX. LES MODELES PROPOSES POUR RENDRE COMPTE DE LA DUREE DE VIE DES FILTRES OU DE LA REPRESENTATION DES COURBES DE FUITE NE SONT PAS TOUJOURS BIEN ADAPTES AU PHENOMENE REEL OU SONT TRES COMPLEXES D'UTILISATION. NOUS AVONS ESSAYE DE FAIRE LE POINT SUR CES DIFFERENTS MODELES, DE MONTRER LEURS ORIGINES COMMUNES, SOUVENT A PARTIR DES EQUATIONS DE BOHART-ADAMS, LES APPROXIMATIONS APPORTEES LIMITANT LEUR DOMAINE D'APPLICATION, LES GRANDEURS QU'ILS PERMETTENT DE DETERMINER: CAPACITE MAXIMUM D'ADSORPTION, COEFFICIENT CINETIQUE D'ADSORPTION, VITESSE DE DEPLACEMENT DU FRONT D'ADSORPTION... DE TOUS CES MODELES, UN SEUL (CLARK, 1987)) PERMET UNE BONNE REPRESENTATION DES COURBES DE PERCEE. NOUS AVONS ETABLI UNE REGRESSION LINEAIRE QUI FACILITE LA DETERMINATION DES PARAMETRES NECESSAIRES AU CALCUL DES COURBES DE FUITE. TOUS CES MODELES ONT ETE TESTES QUE LES RESULTATS EXPERIMENTAUX OBTENUS POUR L'ADSORPTION D'UN TENSIOACTIF ANIONIQUE: LE DECYLSULFONATE DE SODIUM (CLOS), LE 2,6 DIISOPROPYLPHENOL (DIP) ET DES COMPOSES AZOTES, LA PHENYLALANINE ET LA THIOUREE, ET CECI SUR SIX COLONNES DE SECTIONS IDENTIQUES (1,45 CM#2) ET DE HAUTEURS DIFFERENTES DE CHARBON ACTIF; DES VITESSES DE PASSAGE DE L'ORDRE DE 3, 6, 9, ET 12 M.

Download or read book Contribution l tude de l adsorption de colorants basiques d effluents industriels sur une argile pont e granul e written by Benamar Cheknane and published by . This book was released on 2015 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: L’objectif essentiel de ce travail consiste à préparer des grains, à la fois, uniformes et consistants destinés à l’adsorption dynamique sur lit fixe de certains polluants susceptibles de polluer les eaux. Pour préparer ces grains, nous avons utilisé le procédé de la granulation humide d’une bentonite algérienne initialement traitée et modifiée par pontage à l’aide d’un mélangeur granulateur à haut taux de cisaillement. Les conditions de préparation de ces complexes organo-inorgano-argileux granulés (COIAG) sont liées au rapport massique de mouillage (L/S), à la concentration en liant (silicone) et à la vitesse de rotation du mélangeur. L’application dans l’adsorption en système monocomposé simple et/ou en mélange binaire, en réacteur discontinu, montre bien l’efficacité de cette nouvelle génération de grains adsorbants (qmax>350 mg/g à pH=6) vis-à-vis des deux colorants utilisés (Jaune Basique 28 -JB28- et Vert Malachite -VM-). Par ailleurs, les résultats de l’adsorption en mode continu (en réacteur à lit fixe ascendant) montent globalement que la durée de vie du lit de l’adsorbeur dépend essentiellement de la vitesse superficielle du flux entrant, de la concentration initiale en polluant et de la hauteur du lit d’adsorbant.

Download or read book Agricultural English written by Georgeta Raţă and published by Cambridge Scholars Publishing. This book was released on 2012-04-25 with total page 385 pages. Available in PDF, EPUB and Kindle. Book excerpt: Agricultural English is a collection of essays on the English of Agriculture. The approach is a linguistic one: the different aspects of the English used in the field of agriculture (agricultural practices, agricultural systems) and in some fields related to agriculture (agricultural zoology, agri-tourism, biology, botany, ecology, entomology, gastronomy, land measurement, plant pathology, zoology) are analysed from a morphological (combination, derivation), syntactical (nominal phrases, verbal phrases), lexical and lexicographical, semantic (homonymy, semantic fields, synonymy, terminology), pragmatic (academic discourse, idiom, metaphor), etymological (etymon, Latin heritage), and contrastive (English–Croatian, English–French, English–German, English–Romanian, Romanian–English) points of view. The book will appeal to agriculturists, animal breeders, professors, researchers, students, and translators from Croatian-, English-, French-, German-, and Romanian-speaking countries, active in their own countries or abroad. The types of academic readership it would appeal to include academic teaching staff, researchers and students in the fields of agriculture and related fields – agricultural zoology, agri-tourism, biology, botany, ecology, entomology, gastronomy, land measurement, plant pathology, and zoology.

Download or read book Light Water Hydrogen written by CRAIG GRIMES and published by Springer Science & Business Media. This book was released on 2007-12-03 with total page 561 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book covers the field of solar production of hydrogen by water photo-splitting (photoelectrolysis) using semiconductor photoanodes. The emphasis of the discussion is on the use of nanotechnology in the field. The theories behind photocatalysis and photoelectrochemical processes responsible for hydrogen production are given in detail. This provides a state-of-the-art review of the semiconductor materials and methods used for improving the efficiency of the processes. The book also gives an account of the techniques used for making the nanostructures.
