Abstract
PROCEDE PERMETTANT DE MAITRISER LA TENEUR EN ALUMINIUM DISSOUS D'UNE SOLUTION CAUSTIQUE DE DECAPAGE D'ALUMINIUM. DE L'ALUMINIUM EST DECAPE DANS UNE SOLUTION CONTENANT DE L'HYDROXYDE DE SODIUM ET DE L'EAU DANS UN RESERVOIR10 OU SE DISSOUT DE L'ALUMINIUM. UNE PORTION DE LA SOLUTION DE DECAPAGE EST INTRODUITE DANS UN REACTEUR20 POUR ABAISSER SA TENEUR EN ALUMINIUM EN FAISANT PRECIPITER L'ALUMINIUM SOUS FORME D'HYDROXYDE D'ALUMINIUM. UNE PORTION DE LA SOLUTION DU REACTEUR EST FILTREE DANS LE RESERVOIR30 PAR LE TAMBOUR FILTRANT32 POUR ENLEVER L'HYDROXYDE D'ALUMINIUM SOLIDE DE FACON A EMPECHER LA PRECIPITATION DANS LE RESERVOIR DE DECAPAGE. LA SOLUTION FILTREE EST RENVOYEE AU RESERVOIR DE DECAPAGE, CE QUI PERMET DE CONTROLER LA TENEUR EN ALUMINIUM DE LA SOLUTION DE DECAPAGE EN EMPECHANT LA PRECIPITATION D'ALUMINIUM DANS CE RESERVOIR.
