Abstract

CUANDO SE LLEVA A CABO UN METODO Y SE UTILIZA UN DISPOSITIVO PARA PURIFICAR EL AGUA, UN AFLUENTE DE AGUA CONTAMINADA SE CONVIERTE EN UN FLUJO DE PRESION ELEVADA QUE SE DIVIDE, EN UNA UNIDAD DE PURIFICACION, EN UN EFLUENTE PURIFICADO Y UN EFLUENTE CONTAMINADO, QUE A SU VEZ SE DIVIDE EN UN FLUJO DE RETORNO Y EN UN FLUJO DE RECHAZO. CON EL FIN DE OBTENER UN GRAN FLUJO DE RETORNO A ALTA PRESION PARA LIMPIAR MEDIANTE ENJUAGUE LA UNIDAD FILTRANTE DURANTE EL FUNCIONAMIENTO, CON LA INVENCION SE PROPONE, ENTRE OTRAS COSAS, QUE EL FLUJO DE RETORNO INCLUYA UN PRIMER FLUJO DE RETORNO (CONDUCTO DE RETORNO 24) QUE SE RECICLA AL FLUJO DE PRESION ELEVADA (CONDUCTO DE PRESION 16) Y QUE ES ESENCIALMENTE MAYOR QUE EL AFLUENTE E INCLUYE ADEMAS UN SEGUNDO FLUJO DE RETORNO (CONDUCTO DE RETORNO 34) CON UNA PRESION RESTRINGIDA (VALVULA LIMITADORA DE PRESION 28) RESPECTO AL PRIMER FLUJO DE RETORNO Y EL SEGUNDO FLUJO DE RETORNO RETORNA AL AFLUENTE (CONDUCTO DE ENTRADA 14).
