Abstract

EL PROCESO PROPUESTO PARA EL TRATAMIENTO CONTINUO DE AGUAS RESIDUALES QUE CONTIENEN METALES EN DISOLUCION INCLUYE UNA PRECIPITACION POR NEUTRALIZACION UTILIZANDO SOLUCIONES DE CAUSTICO ALCALINO, CARBONATO ALCALINO Y/O LECHADA DE CAL. A CONTINUACION SE REALIZA UNA PRECIPITACION CON SULFURO PARA ELIMINAR LOS RESIDUOS METALICOS QUE PERMANECEN EN LAS AGUAS RESIDUALES.
