Abstract
A cross-now 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 membra nes provided up to 72% greater aeration than a ring-sparger located in the bioreactor. In biological treatment of dairy food process waste, the air back-flush had the additional benefit of inhibiting membrane f ouling, thereby maintaining higher (by about 100%) permeate fluxes.
