Characterizing the Drivers of Carbon Use in Post-Anoxic Denitrification
… on the PAO population. Shorter aerobic times and more acetate in the anaerobic stage were shown to increase internal C denitrification rates to varying degrees, and this type of denitrification was only observed for bio-P biomass that was also nitrifying. Beyond internal carbon, other …

The suitability of the microalgal metabolism for the recovery of nutrients from wastewater: the implications of solids residence time and diel cycles
… recovery process, and the implications of solids residence time (SRT) and diel cycles on microalgal metabolism influencing wastewater treatment. Experimental results showed that SRT dictated intracellular nitrogen to phosphorus ratio of microalgal biomass, while 24-hour (i.e., continuous) …

Evaluating the Source-Effect Relationship of Industrial Toxins in Wastewater Treatment
… a large database of results for comparison over time. Additionally, a small volume contributor, that was thought by the utility to be an unlikely source of problems, contributed significantly to the wastewater oxygen demand and demonstrated inhibitory properties. The modified respirometric …

Community structure and function of mixed microalgal communities for nutrient recovery and the selection of lipid and carbohydrate accumulators for enhanced feedstock production in wastewater treatment
… and lipids. Specifically, this work leveraged solids residence time (SRT) as a parameter that influences system wide performance and examined (1) nutrient (i.e., nitrogen and phosphorus) recovery via microalgal biomass assimilation, (2) eukaryotic and bacterial community structure, and (3) …

Impact of daytime nitrogen limitation on structure and function of mixed microalgal communities derived from three geographically distinct sources
… operated in sequencing batch mode with an 8-day solids residence time (SRT) and 14hr:10hr light:dark cycle with nighttime N-feeding and daytime N-limitation. Metrics of community function included nutrient dynamics and biomass composition which were monitored over the course of 82 days and during …

Seasonal influent characterization, model calibration, SRT and energy usage for nitrogen removal at a full scale wastewater plant
… (COD components), solid retention times (SRTs), and temperatures on denitrification rates in a full scale system, including evaluation of seasonal effects. In order to investigate seasonal variations, four seasonal sampling campaigns were conducted (October 2010, January 2011, May …
