Abstract

Se da a conocer un proceso para disminuir el fósforo en los efluentes de un proceso de pulpeo (1). El proceso comprende: combinar una pluralidad de efluentes ácidos (2, 2', 2'') a obtener a partir del proceso de pulpeo para obtener una corriente de efluentes ácidos (3); la combinación de una pluralidad de efluentes alcalinos (4, 4', 4'') a obtener a partir del proceso de pulpeo para obtener una corriente de efluentes alcalinos (5); tratar al menos una porción (6) de la corriente de efluentes ácidos ajustando el pH de la misma a alcalino con un agente alcalinizante (7).
