“…The push from regulatory agencies has sent municipal wastewater treatment plants searching for alternative solutions to meet N limits (Wright 2004;Constantine et al 2005). The treatment of sludge digester supernatant is one option to reduce nitrogen discharge and has received considerable attention in the past decade.…”

“…The high NH 3 concentration in the recycled supernatant can potentially upset the main treatment process. The appeal of treating the supernatant side-stream is mainly due to the economic aspects such as smaller reactor sizes and lower operational costs (Wright 2004;Constantine et al 2005).…”

“…Sidestream treatment based on the nitritation or anammox process is attractive to the wastewater industry as significantly less carbon and oxygen is required for removing nitrogen compared to conventional nitrification / denitrification (Constantine et al 2005). Typically, these types of processes provide a significantly higher degree of nitrogen removal (up to 80%) than traditional sidestream treatment processes undergoing full nitrification (about 10-20% without external carbon addition).…”

“…This would include utilization of a plug flow reactor with the ability to introduce supplemental alkalinity in multiple locations along the length of the reactor and flexibility to modify the aerated fraction of the reactor in response to seasonal temperature changes and influent loading conditions. Parts of the MAUREEN process configuration and operating details are provided in Constantine et al (2005). The baseline operating mode allows the Blue Plains AWTP to nitrify the centrate load in the sidestream reactor, and remove the produced nitrite and nitrate in anoxic zones within the first stage aeration tanks using the main plant's influent organics (BOD).…”
