Abstract

PROCEDIMIENTO DE TRATAMIENTO DE AGUA POR DECANTACION SEGUN EL CUAL, EN UNA CORRIENTE DE AGUA BRUTA A TRATAR, SE INYECTAN UNOS REACTIVOS Y SE CREA UNA ZONA DE MEZCLA Y DE ESTABILIZACION DE LOS COLOIDES (1), SE HACE CIRCULAR ESTA CORRIENTE EN UNA ZONA INTERMEDIA DE AGREGACION (2), DESPUES EN ZONA ZONA DE DECANTACION LAMINAR (8), DE DONDE SE SEPARA EL AGUA PURIFICADA (10). SE CARACTERIZA PORQUE SE INYECTA (5) MATERIAL GRANULAR INSOLUBLE EN EL AGUA Y MAS DENSO QUE ESTA, SEGUN UNA PROPORCION DETERMINADA, EN LA ZONA DE MEZCLA (1) DONDE SE HACE LA CORRIENTE TURBULENTA, SE INTRODUCEN EN LA ZONA INTERMEDIA DE AGREGACION UNAS TURBULENCIAS (7) ADECUADAS PARA MANTENER AL MATERIAL GRANULAR EN SUSPENSION, SE LLEVA LA CASI TOTALIDAD DE ESTE MATERIAL GRANULAR A LA ZONA DE DECANTACION LAMINAR (8), SE EVACUAN LOS LODOS RECOGIDOS EN ESTA ZONA DE DECANTACION LAMINAR, SE EXTRAE DE ALLI (D) EL MATERIAL GRANULAR Y SE RECICLA AL MISMO DESPUES DE LA LIMPIEZA.
