Abstract

PROCEDE SIMPLE PERMETTANT UNE ELIMINATION PRATIQUEMENT TOTALE DES IMPURETES DES EAUX RESIDUAIRES. IL CONSISTE 1 A FAIRE PASSER UN PREMIER COURANT D'UN GAZ EN CONTACT AVEC UN SECOND COURANT D'EAU RESIDUAIRE CONTENANT DES PRODUITS CONTAMINANTS, ET 2 A SEPARER UN TROISIEME COURANT D'EAU RESIDUAIRE DU GAZ AVEC UNE QUANTITE INFERIEURE DE PRODUITS CONTAMINANTS QUE DANS LE SECOND ET A ELIMINER UN QUATRIEME COURANT DU GAZ DE L'EAU RESIDUAIRE CONTENANT LES PRODUITS CONTAMINANTS. APPLICATION A LA PURIFICATION DES EAUX RESIDUAIRES DES USINES DE FABRICATION DES SILICONES.SIMPLE PROCESS ALLOWING A PRACTICALLY TOTAL ELIMINATION OF IMPURITIES FROM RESIDUAL WATER. IT CONSISTS OF 1 MAKING A FIRST CURRENT OF A GAS IN CONTACT WITH A SECOND CURRENT OF RESIDUAL WATER CONTAINING CONTAMINANTS, AND 2 SEPARATING A THIRD CURRENT OF RESIDUAL WATER FROM THE GAS WITH A LOWER QUANTITY OF CONTAMINANTS THAN IN THE SECOND AND TO ELIMINATE A FOURTH FLOW OF GAS FROM THE WASTE WATER CONTAINING THE CONTAMINANTS. APPLICATION TO THE PURIFICATION OF RESIDUAL WATER FROM SILICON MANUFACTURING PLANTS.
