Abstract

L'INVENTION A POUR OBJET UN PROCEDE DE CLARIFICATION DE L'EAU, SUIVANT LEQUEL L'EAU EST MISE EN CONTACT AVEC UN COAGULANTADSORBANT CONSTITUE PAR UN MATERIAU MINERAL OU ARGILEUX PARTICULAIRE FINEMENT DIVISE, LES PARTICULES DISTINCTES AYANT DES DIMENSIONS EGALES OU INFERIEURES A 10 MICRONS ET PRESENTANT UNE MINCE COUCHE SUPERFICIELLE HYDROXYLEE AYANT UN POTENTIEL ZETA POSITIF AU PH D'ADSORPTION, CARACTERISE EN CE QU'ON AJOUTE UN POLYELECTROLYTE A L'EAU, APRES MISE EN CONTACT, ET AVANT SEPARATION DU COAGULANTADSORBANT DE L'EAU.THE OBJECT OF THE INVENTION IS A PROCESS FOR CLARIFYING THE WATER, FOLLOWING WHICH THE WATER IS IN CONTACT WITH A COAGULANT ADSORBING CONSTITUTED BY A PARTICULAR MINERAL OR CLAY MATERIAL FINALLY DIVIDED, THE DISTINCT PARTICLES HAVING DIMENSIONS OF 10 MICRONS OR LESS THAN 10 MICROS. AND PRESENTING A THIN HYDROXYLATED SURFACE LAYER WITH A POSITIVE ZETA POTENTIAL AT ADSORPTION PH, CHARACTERIZED IN THAT A POLYELECTROLYTE IS ADDED TO THE WATER, AFTER CONTACT, AND BEFORE SEPARATION OF THE ADSORBING COAGULANT FROM THE WATER.
