Abstract

sistema e método para alimentação de unidades de membrana imersa. em um sistema de membrana imersa, o afluente escoa para um tanque de membrana aberto. o tanque de membrana pode ter várias unidades de membrana imersa espaçadas horizontalmente. as unidades de membrana imersa podem ter elementos de membrana de chapa plana dentro de um invólucro de membrana. um ou mais dutos são fornecidos no tanque para direcionar o fluxo de afluente para as unidades de membrana imersa. em alguns exemplos, o afluente é dividido em subfluxos que são alimentados através de defletores para uma unidade de membrana imersa correspondente, opcionalmente em quantidades geralmente iguais, opcionalmente em um padrão de fluxo de passagem única. em um processo de operação de um tanque de membrana, o fluxo afluente é direcionado através do fundo do tanque de membrana e dividido em várias porções. cada uma das múltiplas porções é alimentada diretamente no fundo de uma unidade de membrana imersa correspondente localizada no tanque. o afluente pode ser licor misturado em um biorreator de membrana (mbr).
