Abstract

métodos e sistemas para o tratamento de águas residuais marinhas. a presente invenção se refere a um sistema e método para o tratamento de águas residuais a bordo de uma embarcação marítima ou em outra aplicação de espaço limitado onde um tratamento de águas residuais é necessário. de acordo com uma modalidade da presente invenção, dois processos de tratamento de águas residuais de polos opostos são incorporados no mesmo sistema de tratamento. o sistema é uma unidade de tratamento híbrido que combina um tratamento de águas residuais convencional usando uma unidade de tratamento biológico baseado em um processo de reator de biofilme de leito móvel (mbbr) em combinação com um novo processo eletroquímico de oxidação avançada (eaop) por meio de uma recirculação de hipoclorito de sódio no local. o efluente clarificado e desinfetado a partir desta unidade de tratamento híbrido é filtrado a fim de remover os sólidos suspensos totais (sst) residuais. o efluente filtrado e desinfetado é descartado após uma decloração / neutralização. um desinfetante de manutenção no local poderá ser produzido por meio do processo de eletroxidação / eletrocloração / eletroquímico e usado para a limpeza e desinfecção da unidade de tratamento. além disso, a unidade de tratamento provê um fluxo totalmente separado de desinfetante gerado por eletrólise para fins de desinfecção de superfície.
