Abstract
A cross-flow ceramic membrane was coupled to a bioreactor to fulfil the alternate functions of process stream clarifier and primary aerator. At the same air supply rate (delivered as a back-flush), ceramic membranes provided up to 72% greater aeration than a ring-sparger located in the bioreactor. In biological treatment of dairy food process waste, the air backflush had the additional benefit of inhibiting membrane fouling, thereby maintaining higher (by about 100%) permeate fluxes.
