“…In Figure 16, the Belmont monthly average solids production rates from 2006 to October 2013 were plotted with the average MCRT data, where the solids production rates were defined as the ratios of the total wasted TSS in the secondary treatment system to the removed primary effluent BOD5 loading in the secondary process. The data in Figure 16 Figure 16 shows a trend that the solids production rates from 2006 to 2012 decreased substantially as the MCRT increased, which is similar to the trend presented in the paper of Gharagozian et al (2010). However, the data of 2013 did not follow that trend probably because the new AS or ANS/ONS system replaced the original TF/AS or Bio-roughing /ONS process.…”

“…However, the solids production rate of attached growth systems has not been quite understood yet, and it varies widely from one study to another. Gharagozian et al (2010) reported that the solids production rates observed in different-size attached growth/ activated sludge plants were lower than those at suspended activated sludge systems although the exact cause for that was not known. In Figure 16, the Belmont monthly average solids production rates from 2006 to October 2013 were plotted with the average MCRT data, where the solids production rates were defined as the ratios of the total wasted TSS in the secondary treatment system to the removed primary effluent BOD5 loading in the secondary process.…”

The Belmont Advanced Wastewater Treatment (AWT) plant at Indianapolis, IN was built in 1980s. It was a two-stage nitrification facility composed of a bio-roughing process followed by a pure oxygen nitrification system (ONS). The plant was rated at an average capacity of 120 mgd with a peak capacity of 150 mgd. The Belmont AWT plant was upgraded to handle 300 mgd peak flow through its secondary treatment process by the end of 2012. During the plant upgrade, the original two-stage biological nitrification process was converted to a one-stage nitrification process by replacing the deteriorated bio-roughing towers with a new aeration basin. This new aeration basin coupled with the original ONS enabled the plant to treat 300 mgd peak flow without adding additional clarification capacity. This paper was intended to discuss some major opportunities and challenges the newly updated plant is facing by reviewing the data from the first year of operation.
