Abstract

Se proporcionan métodos y sistemas para tratar aguas residuales para retirar simultáneamente nitrógeno, carbono, y fósforo. El proceso incluye un tanque anóxico que recibe por lo menos dos corrientes, que incluyen agua residual de influente de planta y lodo activo de retorno. Estas corrientes se mezclan en el tanque anóxico para promover la fermentación y liberación de materia orgánica disuelta y particulada. El licor mezclado se transfiere a un tanque aireado que tiene bajas concentraciones de oxígeno disueltas para promover el desarrollo de bacterias que liberan fósforo que se reciclan eventualmente en el tanque anóxico por vía del lodo activado de retorno. La nitrificación, desnitrificación y liberación de fósforo simultánea ocurre en el tanque aireado. Un tanque de membrana separa el efluente tratado del lodo activado en un tanque de membrana.
