Abstract

UN CLARIFICADOR (10) CON UNA PRIMERA ETAPA DE FLOTACION Y UNA SEGUNDA ETAPA DE FILTRACION DIVIDE AL MENOS LA PARTE INFERIOR DE UN DEPOSITO DE FLOTACION DENTRO DE CELULAS INDEPENDIENTES (54) UN CONDUCTO RAMIFICADO (78) RECOGE AGUA CLARIFICADA. LAS VALVULAS (76) CONTROLA EL FLUJO DE AGUA CLARIFICADA A CUALQUIER CONDUCTO DE ANILLO DE AGUA CLARIFICADA (62) O A UN PRIMER CONDUCTO DE ANILLO DE FILTRADO/REMOLINO (64) CONECTADO A UN DEPOSITO DE ALMACENAMIENTO (68). LAS GRANDES PAREDES CELULARES (53) Y LOS TABIQUES INCLINADOS (58) RETIENEN EL MEDIO DE FILTRO DURANTE LA FORMACION DE REMOLINOS. UNA VALVULA DE DESCOMPRESION (94) PARA AGUA PRESURIZADA CON AIRE DISUELTO TIENE UNA RANURA ANULAR ESTRECHA ESTABLECIDA POR UN ELEMENTO MOVIL PARA CREAR BURBUJAS DE AIRE MICROSCOPICAS. UM ACCIONADOR NEUMATICO O M MECANICO ABRE PERIODICAMENTE LA RANURA PARA DESCARGAR LAS PARTICULAS ATRAPADAS.
