Abstract

. Método e aparelho para tratar água de lastro de navio antes que ele seja descarregado em águas costeiras. A água de lastro pode conter microorganismos prejudiciais, não-nativos do país. Antes da descarga, a água de lastro é oxigenada e desoxigenada, para reduzir as populações de microorganismos anaeróbicos e aeróbicos, respectivamente. Se os microorganismos não são motivo de preocupação, a etapa de oxigenação pode ser eliminada. O aparelho inclcos aeróbicos. A câmara de vácuo (34) contém um agitador interno (36) para agitar a água de lastro s tempo, para remover o oxigênio dissolvido da água de lastro. O agitador pode ser substituído por um sistema do tipo Weir (42), em que uma série de placas verticais são colocadas de tal maneira que elas formam uma linha de placas que são sempre decrescentemente menores de um influxo (27) para um escoamento (45) da câmara de vácuo (34).
