Remoção de crómio de efluentes industriais por biossorção

Abstract

Os processos físico-químicos clássicos, quando aplicados na remoção de metais pesados presentes em efluentes de baixa concentração e elevado caudal, revelam-se pouco eficientes e demasiado onerosos, sobretudo para as unidades industriais de pequena e média dimensão que proliferam no nosso país. Apesar de diluídos, esses efluentes tornam-se uma ameaça ambiental à escala local e cumulativa. Dentro das novas tecnologias de remediação ambiental, de baixo custo e fácil implementação, aparece recentemente a biossorção que tem-se revelado bastante promissora na fixação de diferentes metais. Este trabalho dá especial atenção à remoção de crómio de águas residuais por recurso a um biofilme bacteriano, Arthrobacter viscosus, suportado em carvão activado granular.
