The high cost of upgrading a municipal wastewater treatment plant for increased organic capacity or stringent effluent requirements has urged many investigators to examine bioaugmentation as a means to improve the economics of wastewater treatment. A full-scale wastewater treatment
plant selected an external bioaugmentation process to continuously add high concentrations of select, facultative, non-pathogenic bacteria. Bacteria are added to the outer reaches of the wastewater collection system in order to grow throughout the surface of the sewer pipes and thereby modify
the sewer biofilm; improve the ability of the sewer biofilm to degrade the organic material; and take advantage of the residence time of the wastewater within the sewer to degrade the waste. A comparative study illustrates a correlation of improved operating data to increased metabolism of
wastewater characteristics that result in operational performance at the plant by transforming the collection system into an active part of the wastewater treatment process. This report describes the performance metrics, the history and discussion of the plant, and the environmental impacts
and plant performance improvements resulting from bioaugmentation.
