A method for continuously processing biodegradable organic waste in an aqueous medium which comprises continuously serially passing an organic waste-containing aqueous medium through a first immobilized microbe bioreactor and a second immobilized microbe bioreactor, in which: A. The first bioreactor is a hydrolytic redox bioreactor containing a porous inorganic support having a pore diameter distribution of from about 0.8 to about 30mand microbes immobilized within the pores thereof, in which bioreactor the dissolved oxygen originally present in the aqueous medium is substantially depleted, and B. the second bioreactor is an anaerobic bioreactor containing a porous inorganic support having a pore diameter distribution of from about 0.8 to about 30mand microbes immobilized within the pores thereof, in which bioreactor oxygen is substantially absent. A method for processing biodegradable organic waste in an aqueous medium which comprises serially passing an organic waste-containing aqueous medium through a first immobilized microbe bioreactor and a second immobilized microbe bioreactor, in which: A. the first bioreactor is a hydrolytic redox bioreactor containing a porous inorganic support which is suitable for the accumulation of a biomass, and B. the second bioreactor is an anaerobic bioreactor comprising a controlled-pore, hydrophobic inorganic membrane which contains a porous inorganic support which is suitable for the accumulation of a biomass, in which at least about 90 percent of the pores of the inorganic membrane have diameters of from about 100 A to about 10,000 A.
