Nutrient Removal from Anaerobic Digester Side-Stream at the Blue Plains AWTP

Implementation of a novel sidestream treatment configuration will provide the Blue Plains AWTP sidestream treatment process the flexibility to operate in four different process modes including the MAUREEN, SHARON, STRASS and DEMON configurations. Each process confers specific benefits to the AWTP that will need to achieve stringent nutrient limits to support ongoing efforts within the Chesapeake Bay area. In order to maximize the operating cost savings, while also assuring that treatment goals are achieved, the MAUREEN process configuration can be deployed in two seasonal modes, providing differing levels of preferential nitritation and bioaugmentation. To maximize operating cost savings, when performance is not limited by temperature, configurations such as SHARON, STRASS or DEMON would be utilized.
