Abstract
Se proporciona una descripción de una planta de tratamiento de aguas negras, en particular una planta de tratamiento de aguas negras pequeña que comprende al menos un tanque de activación para agua residual y/o que comprende al menos un tanque de clarificación secundario para agua residual, en donde el tanque de activación y/o el tanque de clarificación secundario se llenan con cuerpos moldeados que se suspenden libremente en el agua residual, caracterizada en que tiene al menos un dispositivo de filtración para purificación del agua residual, dispositivo de filtración este que comprende al menos una membrana a base de cerámica para separar microorganismos. Se revela además un método para purificación de agua residual que comprende una purificación biológica del agua residual mediante microorganismos en al menos un tanque de activación y/o que comprende una clarificación secundaria del agua residual en al menos un tanque de clarificación secundario, en donde, para la purificación, el mínimo de un tanque de activación y/o el mínimo de un tanque de clarificación secundario se llena con cuerpos moldeados, caracterizado en que los microorganismos situados en el agua residual se separan mediante al menos una membrana a base de cerámica.
