Abstract
NUEVOS PROCESO DE COAGULACION-FLOCULACION QUE CONDUCE A LA FORMACION DE FLOCULOS DE MAYOR TAMAÑO Y DE MAYOR RESISTENCIA MECANICA SIN FORMACION IRREVERSIBLE DE MICROFLOCULOS. COMPRENDE APLICAR, AL MENOS EN LA FASE INICIAL DEL PROCESO, UN CICLO OPERATIVO INICIAL A UNA SUSPENSION QUE TIENE PROPIEDADES FORMADORAS DE AGREGADOS Y QUE CONTIENEN UN COAGULANTE, COMPRENDIENDO DICHO CICLO (I) UNA ETAPA DE AGITACION RAPIDA A UN GRADIENTE DE VELOCIDAD EN PROMEDIO ENTRE 300 Y 1.000 S-1 DURANTE UN TIEMPO ENTRE 30 Y 200 SEGUNDOS; Y (II) UNA ETAPA DE AGITACION LENTA A UN GRADIENTE DE VELOCIDAD EN PROMEDIO ENTRE 40 Y 100 S-1 DURANTE UN TIEMPO ENTRE 5 Y 40 MINUTOS.
