Abstract

MÉTODO PARA FILTRAGEM DE FLUIDO Um método para filtragem de fluido, principalmente líquido, com dispositivo de filtragem de fluido tendo uma entrada de fluido e uma saída de fluido e um trajeto de fluido entre a entrada e a saída, através de um filtro microporoso com um tamanho de poro adaptado para filtrar bactérias ou bactérias e vírus por separação mecânica de tamanho de partícula. O dispositivo de filtragem compreende ainda uma fonte antimicrobiana adicionando substância antimicrobiana ao fluido no trajeto de fluido entre a entrada de fluido e a superfície de entrada do filtro microporoso. O dispositivo de filtragem de fluido é provido com um fluxo do projeto através do dispositivo, o fluxo do projeto assegurando uma apropriada filtragem do fluido fluindo através do dispositivo com um fluido limpo na saída de fluxo. A fonte antimicrobiana, por exemplo, uma fonte de halogênio, é configurada para liberar a substância antimicrobiana em uma baixa taxa de eluição, que não é bastante elevada para matar substancialmente todos os micróbios do fluido durante o tempo que leva para o fluido escoar através do dispositivo no fluxo do projeto, mas que é bastante elevado para evitação de uma biopelícula a longo prazo.
