Abstract

EN UNA MEZCLA DE MEDIOS FLOCULANTES DENTRO DE UNA SUSPENSION DE PRECIPITADO QUE SE DESAGUA EN UN CONDUCTO DE PRESION ENTRE UNA BOMBA DE ALIMENTACION (1) Y UN DISPOSITIVO DE DESAGUE (5) SE CAMBIA LA DISTANCIA ENTRE LA POSICION DE MEZCLA (7.7'', 7") Y LA ENTRADA EN EL DISPOSITIVO DE DESAGUE (5) DURANTE EL ACCIONAMIENTO, POR EJEMPLO MIENTRAS SE REMUEVE UNA ESPATULA QUE TRANSPORTA UNA CABEZA MEZCLADORA EN EL CONDUCTOR DE PRECIPITADO O MIENTRAS SE TOMAN A ELECCION ALGUNAS POSICIONES MEZCLADORAS (7, 7'', 7") COLOCADAS A DIFERENTES DISTANCIAS DEL DISPOSITIVO DE DESAGUE. POR ESTA RAZON SE PUEDE OPTIMIZAR EL TIEMPO DE PERMANENCIA QUE EXISTE PARA LA FORMACION Y MADURACION DE PRECIPITADOS FLOCULANTES A DISPOSICION CON RESPECTO A LAS CONDICIONES DOMINANTES MOMENTANEAS ASI COMO EL TIPO DE MEDIO FLOCULANTE AÑADIDO.
