摘要 |
A wastewater treatment system comprising: a first treatment zone (11) fluidly connected to one or more further treatment zones (12-14), a membrane module (16) comprising a filter membrane is positioned in or fluidly connected to the further treatment zone; and a gravity settling device (15) fluidly connected to the first treatment zone (11) to receive overflow therefrom. A method of treating wastewater comprising flowing wastewater through one or more treatment zones (11-14) to produce a fluid product which is passed through a filter membrane (16) to produce a concentrated mixed liquor and a filtrate; returning at least a portion of the concentrated mixed liquor to at least one of the treatment zones (11); when the flow of wastewater water exceeds a predetermined level, flowing a portion of the returned mixed liquor to a gravity settling device (15) and clarifying the mixed liquor within the gravity settling device (15).
