Abstract: An improved treatment of manure from animal husbandry results from using a hybrid upflow, anaerobic contact reactor that maintains a flocculent bed of solids in combination with a microfiltration/ultrafiltration system and a recycle flow arrangement. This hybrid anaerobic contact reactor arrangement provides a high conversion of COD and volatile suspended solids in the anaerobic contact reactor by maintaining a flocculent region of solids and direct recycle of an aliquot portion of the effluent stream from the anaerobic contact reactor. The direct recycle facilitates the adjustment of the hydraulic retention time versus the solids retention time within the anaerobic contact reactor. The provision of concentrate from the microfiltration/ultrafiltration system increases solids retention time in the anaerobic contact reactor. This arrangement eliminates additional processing steps and equipment typically used in treating flush manure.
