Abstract

"PROCESSOS PARA A PRODUçãO DE DIóXIDO DE CLORO E PARA O TRATAMENTO DE áGUA CONTAMINADA, E APARELHOS PARA A FABRICAçãO DE DIóXIDO DE CLORO E PARA A DESINFECçãO DE áGUA CONTENDO CONTAMINANTES". Um processo para a formação de uma solução aquosa de dióxido de cloro é descrito o qual inclui a reação em um vaso de reação de uma solução de reação ácida contendo um ácido hidróxi-carboxílico e um ácido acompanhante com um sal de metal alcalino de um íon clorito. De acordo com o processo, o ácido hidróxi-carboxílico serve para transferir temporariamente cloro do sal de metal alcalino de um íon clorito e não formar um sal com o sal de metal alcalino de um íon clorito. A solução aquosa de dióxido de cloro produzida está substancialmente livre de ácido cloroso e de preferência está livre de outros subprodutos tais como cloreto de sódio e cloro livre. O processo inclui adicionalmente a manutenção do vaso de reação em um pH menor do que 5 e/ou a remoção de pelo menos uma porção de dióxido de cloro da solução aquosa de dióxido de cloro. O processo permite rápida, segura, eficiente e compacta geração de dióxido de cloro. um processo de desinfecção de água, e Aparelho para fabricação de dióxido de cloro e para desinfecção de água também são fornecidos.
