Abstract

Se provee un sistema de tratamiento de agua residual que comprende un reactor biologico que tiene un subsistema de separacion, un sistema de suspension y un sistema de operacion de membrana. El subsistema de separacion está construido y dispuesto para mantener al material adsorbente en el reactor biologico con un licor mezclado. El sistema de suspension está dispuesto en el reactor biologico y construido y configurado para mantener al material adsorbente en suspension con el licor mezclado. El sistema de operacion de membrana está ubicado corriente abajo del reactor biologico y construido y configurado para recibir al licor mezclado tratado desde el reactor biologico y descargar un permeado de membrana. Además, se provee un sistema de tratamiento de agua residual que comprende una primera zona de reaccion biologica, una segunda zona de reaccion biologica y un sistema de operacion de membrana. La primera zona de reaccion biologica está construida y dispuesta para recibir y tratar el agua residual. La segunda zona de reaccion biologica incluye un subsistema de separacion y está construida y dispuesta para recibir el efluente de la primera zona de reaccion biologica. Un sistema de suspension de material adsorbente se provee en la segunda zona de reaccion biologica. El sistema de operacion de membrana está ubicado corriente abajo de la segunda zona de reaccion biologica y construido y dispuesto para recibir el agua residual tratada desde la segunda zona de reaccion biologica y descargar un permeado de membrana.
