Abstract

SE DESCRIBE UN PROCESO MEJORADO PARA LA EXTRACCION DE LOS METALES DISUELTOS PRESENTES EN AGUAS RESIDUALES, UTILIZANDO UN SISTEMA DE RECICLADO DEL CIENO DE ALTA DENSIDAD. EL PROCESO CONSISTE ESPECIFICAMENTE EN LOS PASOS DE: 1) TRATAR EL AGUA RESIDUAL QUE CONTIENE LOS METALES DISUELTOS CON UN CHORRO DE RECICLADO QUE CONTENGA PARTICULAS DE RECICLADO TENSOACTIVAS ALCALINAS PARA PRECIPITAR LOS METALES DISUELTOS EN LA SUPERFICIE DE LAS PARTICULAS DE RECICLADO (21); 2) TRATAR UNA PORCION DEL AGUA RESIDUAL TRATADA QUE CONTENGA SOLIDOS PRECIPITADOS METALICOS CON UN REACTIVO ALCALINO PARA FORMAR PARTICULAS DE RECICLADO, TENSOACTIVAS, ALCALINAS (28); 3) RECICLAR EL CHORRO TRATADO ALCALINO QUE CONTIENE LAS PARTICULAS TENSOACTIVAS ALCALINAS (31); Y (4) SEPARAR LA PORCION DEL CHORRO DEL PASO 1) NO TRATADA CON UN REACTIVO ALCALINO EN UN COMPONENTE DE AGUA QUE NO TENGA METALES DISUELTOS NI SOLIDOS Y EN UN COMPONENTE DE CIENO QUE CONTENGA SOLIDOS (23). EL PROCESO MEJORADO ES AUN MEJOR SI SE UTILIZA UN PASODE CLASIFICACION DE SOLIDOS PARA SEPARAR PREFERENTEMENTE LAS PARTICULAS PRECIPITADAS DE METAL MAS FINAS, QUE SE TRATAN CON UN REACTIVO ALCALINO Y SE RECICLAN, DE LAS PARTICULAS PRECIPITADAS DE METAL DE MAYOR TAMAÑO, QUE SE DESCARTAN.
