Methods for reducing biosolids odors

A method for reducing odors emitted by anaerobically digested dewatered biosolids, comprising:

• dewatering first anaerobically digested biosolids;
• after dewatering, mixing the first anaerobically digested biosolids with second anaerobically digested biosolids stored in an area for at least approximately three days under conditions that promote growth of anaerobic microorganisms;
• and
• storing the mixed biosolids in the area.

A method for reducing odors emitted by anaerobically digested dewatered biosolids, comprising:

• providing to a mixing area anaerobically digested biosolids;
• providing to the mixing area anaerobically digested biosolids stored for at least approximately three days under conditions that promote growth of anaerobic microorganisms;
• mixing the anaerobically digested biosolids and the stored anaerobically digested biosolids to form mixed biosolids;
• and
• moving the mixed biosolids to a storage area, wherein the stored anaerobically digested biosolids comprise at least a portion of the mixed biosolids stored in the storage area for at least approximately three days.
