Abstract

PROCESSO PARA A REMOçãO SIMULTáNEA DE BOD E FOSFATO DE UM LìQUIDO CONTENDO AMÈNIO, BOD, FOSFATO E MAGNéSIO, E, APARELHO PARA A REMOçãO SIMULTáNEA DE BOD E FOSFATO DE UM LìQUIDO A invenção é direcionada um processo para a remoção simultânea de BOD e fosfato de um líquido contendo amónio, BOD, fosfato e magnésio, o método compreendendo: alimentar o líquido a um reator contendo biomassa de oxidação de BOD; garantir que o líquido no reator contenha um excesso para a estequiometria de amónio e magnésio em relação a fosfato, em que a estequiometria é relacionada à estequiometria de estruvita; oxidar pelo menos parte do BOD; ajustar o pH do líquido no reator em um valor desejado; formar o material sólido no reator, o material sólido compreendendo estruvita; separar pelo menos parte do material sólido compreendendo estruvita do efluente de reator; devolver uma parte do material sólido ao reator. A invenção também é direcionada a um reator para este processo. A vantagem do processo e do aparelho é que em um reator tanto BOD quanto fosfato são removidos do líquido.
