Abstract: Systems and methods for wastewater treatment are described. In some embodiments, a wastewater treatment system may include a container configured to receive and store at least a portion of incoming wastewater during a digestion process that generates biogas and a biogas burner. The biogas burner may be arranged to receive and burn at least a portion of the biogas generated by the digestion process. The system may be configured to heat solids separated from the wastewater such that: (i) the solids separated from the wastewater are maintained at a temperature of at least 70° C. for at least 30 minutes; and/or (ii) a water content of the solids separated from the wastewater is less than 15% by mass.
