Abstract

Patente de Invenção: <B>"PROCESSO E DISPOSITIVO DE PURIFICAçãO DE áGUAS SERVIDAS, COMPREENDENDO UM TRATAMENTO ADICIONAL DAS LAMAS POR OZONIZAçãO"<D>. A invenção refere-se a um método para purificar as águas servidas, no qual a água servida é submetida a um tratamento biológico (3), produzindo lama, parte dessa lama sendo reciclada para o tratamento biológico, enquanto é submetida à ozonização combinada com uma agitação mecânica (9). Uma energia de agitação mecânica é criada para atacar as paredes dos microorganismos.
