Characterizing the Drivers of Carbon Use in Post-Anoxic Denitrification
… Recovery Facilities (WRRFs) add methanol for post-anoxic denitrification: the Virginia Initiative Plant (VIP), Nansemond Plant (NP), and Army Base (AB). From 2017-2020, VIP averaged 0.49 ± 0.03 lb COD/lb N removed, while NP and AB averaged 1.48 ± 0.06 and 2.11 ± 0.15 lb COD/lb N, respectively. …

Optimizing Enhanced Biological Phosphorus Removal at WRRFs: Impact of Low DO Operation and Full-Scale Strategies
… fueled by internally stored carbon in the post-anoxic zone were found to co-occur with elevated PAO activity, and subsequent batch tests indicated post-anoxic phosphorus uptake rates ranging from 3 to 40 percent of the aerobic phosphorus uptake rates. Removing the aerobic phase in batch …

The Effect of Slowly Biodegradable Carbon on the Morphology, Integrity and Performance of Aerobic Granular Sludge
… SBR cycle. To achieve complete BNR, a post anoxic cycle was included in the SBR cycle. During the second experimental phase, the influence of particulate COD was studied with particulate potato starch being added with and without pretreatment. In the first reactor, particulate starch …

The Middle to Late Cretaceous microbiostratigraphy (foraminifera) and lithostratigraphy of the Cauvery Basin, Southeast India
… from the late Cenomanian to mid-Turonian, when anoxic conditions developed in the Basin. These anoxic events record major taxonomic changes in the planktonic foraminiferal assemblage. The study shows that the anoxic events had a major affect on the microfaunal community and that the post anoxic …

The Investigation of Nitrite Accumulation and Biological Phosphorus Removal in an Intermittently Aerated Process Combining Shortcut Nitrogen Removal and Sidestream Biological Phosphorus Removal
… because profiles and activity tests showed anoxic nitrite accumulation at the end of the aerobic process. Post-anoxic denitrification using internally stored carbon compounds has been observed in other EBPR systems (Vocks, Adam, Lesjean, Gnirss, and Kraume, 2005). Fermentate addition was …
