An important component in the operation of large wastewater treatment plants is the Anaerobic Sludge Digestion process. The main aims are to improve the biological conversion rates, maximize gas generation volumes as an energy resource, and minimize sludge disposal volumes that represent a cost to plant operations.
This paper will show that through the innovative use of proven process technologies, a significant improvement in the biological conversion process can be realized utilizing an external recirculation system incorporating a low-pressure homogenizer for digester sludge treatment. We shall show how higher organic conversion rates, increases in energy production (biogas yields), and reduction in sludge volumes can be achieved, and how a net positive financial benefit may be realized after a relatively short payback period.
