Methods of treating animal organic material are disclosed herein. The methods include diluting the animal organic material to produce an organic material slurry, anaerobically digesting the organic material slurry to produce a biogas and a digestate, separating the digestate to produce a digestate solids and a filtrate, removing ammonia from the filtrate, removing organic contaminants and divalent anions from the filtrate, concentrating the filtrate to produce a retentate and a permeate, combining the digestate solids and the retentate to produce a solids product, and returning the permeate to dilute the animal organic material. Systems for treatment of animal organic material are also disclosed herein. The systems include a dilution tank, an anaerobic digester, a first solids-liquid separation subsystem, an ammonia-reducing column, a second solids-liquid separation subsystem, a production water storage tank, and a solids product tank.
