March 2013 Emerging Technologies Phosphorus Removal prepared 2008 Technology Summary Modified Anaerobic/Oxic (A/O) Process Objective: State of Development: Enhanced removal of phosphorus and nitrogen from Adaptive Use. wastewater. Description: The modified A/O process provides phosphate and nitrogen removal. If nitrification is not required and the temperatures are not high, the simple two-stage, high-rate A/O process may be sufficient. However, with higher temperatures some nitrate formation cannot be avoided. Therefore, returned activated sludge (RAS) should be subjected to an anoxic stage to remove nitrates before mixing it with the influent wastewater. Comparison to Established Technologies: The simple high-rate A/O process uses an anaerobic reactor upstream of the oxic reactor. RAS is returned to the anaerobic reactor. The modified A/O process, however, includes an anoxic reactor downstream of the anaerobic reactor where only RAS is recycled. Influent wastewater is directly sent to the anaerobic reactor for phosphorus removal. There is an internal recirculation from the anoxic reactor to the anaerobic reactor. Available Cost Information: Approximate Capital Cost: Cost estimates are dependent upon local requirements and specific application and economy of scale applies. For example, uniform annual cost of a 100,000 GPD plant is estimated about $244,000 based on an interest rate of 6 percent for a 20-year period.
