Description:
The study identified methods of treating and disposing of septic tank sludge (septage). Biological, chemical, and physical properties of septage were determined and curves were developed for designing septage treatment facilities. Two processes were tested for treating and disposing of septage. Injecting septage in the soil appears to be practical, but is limited to periods when the ground is not frozen. A bench and pilot process that reduced BOD5, COD, and Kjeldahl nitrogen by 93 percent or more consisted of anaerobic digestion-aeration-sand filtration. Consideration was given to treating septage in publicly owned wastewater treatment plants with municipal wastewater. Criteria for desirable receiving facilities were developed.
