Darius, Of course you could convert a SBR to extended aeration with addition of solids separation by a clarifier or membrane unit. But had you considered the possibility of continuing to operate in SBR mode but encouraging aerobic granular sludge? This could permit higher SRT plus nitrogen and phosphorus removal. Take a look at the Nereda process (https://www.royalhaskoningdhv.com/nereda). Cheers, Randal
