Moving-bed biofilm membrane reactor

The basic advantage of the suspended biofilm membrane reactors over the suspended biomass system (either with dispersed cells or with floes) is that the former are able to retain much more biomass [22]. It substantially reduces the biomass wash out and allows a more stable operation with higher biomass concentration. A moving-bed-biofilm membrane reactor is illustrated in Figure 14.5. The biomass is immobilized inside and outside of the fluidized particles. The structure of the biofilm continuously...
