Abstract

PROCEDIMIENTO PARA PURIFICAR AGUAS RESIDUALES FLUORADAS. SE EFECTUAN LAS SIGUIENTES OPERACIONES: 1 ) HACER REACCIONAR LAS AGUAS FLUORADAS A UNA TEMPERATURA ENTRE 0 Y 100 C CON AL MENOS UN ALUMINATO ALCALINO SOLUBLE EN AGUA. 2 ) AJUSTAR EL PH DE LA MEZCLA DE REACCION A UN VALOR DE 4 A 9 POR ADICION DE ACIDOS, GASES ACIDOS Y/O SALES DE REACCION ACIDA, PREFERENTEMENTE POR ADICION DE DIOXIDO DE CARBONO A PRESION ELEVADA. 3 ) SEPARAR LOS SOLIDOS PRECIPITADOS POR FILTRACION, SEDIMENTACION O CENTRIFUGADO. EL AJUSTE DEL PH SE LOGRA PREFERENTEMENTE MEDIANTE ALIMENTACION DE DIOXIDO DE CARBONO BAJO PRESION ELEVADA.
