Abstract

1 / 1 resumo “mã‰todo para a desinfecã‡ãƒo eletroquã�mica de ã�gua â€� a invenã§ã£o se refere a um mã©todo para a desinfecã§ã£o eletroquã­mica de ã¡gua passando-se essa ã¡gua atravã©s de pelo menos uma cã©lula contida em um alojamento dotado de meios para transferir e remover a ã¡gua. o mã©todo de acordo com a invenã§ã£o ã© caracterizado por consistir em: a) usar uma cã©lula eletrolã­tica que tem um ã¢nodo e um cã¡todo, ambos em formato de placa, e paralelos um ao outro, cujas faces catalã­ticas opostas tãªm ã¡reas de superfã­cie idãªnticas e formam um espaã§o simã©trico entre os eletrodos sem nenhum trajeto preferencial ou curto-circuito; b) criar, entre as ditas placas, ao longo de toda a extensã£o da passagem da ã¡gua a ser tratada, um regime turbulento que tem o efeito de fundir, de modo alternativo e bem sucedido, os micro-organismos contidos nas substã¢ncias dissolvidas contra o ã¢nodo e contra o cã¡todo para que sejam submetidos ao efeito de desativaã§ã£o causado pelas fortes variaã§ãµes de ph que estã£o presentes entre os eletrodos e o efeito bactericida adicional mediante o contato com os radicais de o e oh formados na superfã­cie dos eletrodos. 2
