Abstract

"MéTODO PARA LIMPAR UM APARELHO DE FILTRAGEM DE MEMBRANA IMERSA". Um método para limpar um aparelho de filtragem compreendendo uma pluralidade de membranas imersas em pelo menos um tanque contendo o efluente a ser tratado. De acordo com o método, o efluente é pelo menos parcialmente removido do tanque para expor as membranas ao ar, e pelo menos uma solução de limpeza é alimentado através das ditas membranas na direção oposta ao fluxo de filtragem do efluente distribuindo a dita solução de filtragem ao lado penetrado das ditas membranas.
