Abstract
<B>SISTEMA DE AERAçãO CìCLICA PARA MóDULOS DE MEMBRANA SUBMERSOS<D>. Um sistema de aeração, para um módulo de membrana submerso, tem um conjunto de aeradores, conectados a um soprador de ar, válvulas e um controlador, adaptados para alternadamente proverem uma vazão mais alta de ar e uma vazão mais baixa de ar em ciclos repetidos. Em uma montagem, o soprador de ar, as válvulas e o controlador, simultaneamente, provêem o fluxo de ar alternado para dois ou mais conjuntos de aeradores, de modo que o fluxo total de ar seja constante, permitindo que o soprador seja operado a uma velocidade constante. Em uma outra montagem, os ciclos repetidos são de curta duração. Condições de fluxo transiente resultam na água do tanque, o que evita espaços mortos e ajuda na agitação das membranas.
