ABSTRACT:
A method is provided for producing a balanced fertilizer from an anaerobic digestion process. The process includes anaerobically digesting a diluted influent mixed slurry in a digestion area and producing an effluent. The process includes separating water from the effluent to produce a liquid effluent, which is used as recycle water and a dewatered solids effluent. The process includes separating toxic compounds from the recycle water via a toxics strip and recovery area. The process includes mixing the detoxified recycle water with an influent solids slurry in a mixing area to provide the diluted influent mixed slurry. The process includes combining the toxic compounds with the dewatered solids effluent to produce a balanced fertilizer.
