Abstract

"SISTEMA E PROCESSO PARA TRATAMENTO DE áGUAS RESIDUáRIAS". Compreendendo um primeiro módulo eletroquímico provendo a produção de cátions in situ que participam de reações de hidrólise formando coágulos e pelo menos um módulo de separação da fase sólida da água tratada. O módulo eletroquímico compreende um catodo e um anodo metálico de sacrifício, podendo-se utilizar neste eletrodo o alumínio ou o ferro. A aplicação de corrente elétrica a ditos eletrodos resulta na produção de cátions metálicos a expensas do anodo de sacrifício, seguida da formação de coagulante mediante hidrólise. A segregação da água tratada dos demais materiais ocorre por flotação num segundo módulo - e, eventualmente, num terceiro módulo - onde são geradas bolhas que se agregam aos flocos formados pelo coagulante, bem como aos óleos, graxas e partículas em suspensão, formando uma espuma que sobrenada a água tratada, possibilitando sua remoção. A reação de hidrólise é otimizada mantendo-se o pH do líquido dentro de uma faixa predeterminada de valores.
