title = "The effects of solids residence time and diurnal cycles on nutrient recovery and biochemical composition in microalgae",
abstract = "Microalgal treatment systems could dramatically improve nutrient recovery in water resource recovery facilities (WRRFs) by achieving effluent nitrogen and phosphorus levels below the current limit of technology (LOT), while simultaneously producing a valuable biomass feedstock. This research isolates the effect of solids residence time (SRT) and diurnal light variation on nutrient uptake and carbon storage in two species of microalgae, Scenedesmus obliquus and Chlamydomonas reinhardtii. SRT dictated intracellular N:P ratio, 24-hour (i.e., continuous) removal of N and P was achieved, and levels of stored carbohydrates increased and decreased in phase with light intensity. The relationship between SRT and N:P ratio was validated using established models, but a simplified model is also proposed for use in phototrophic wastewater process modeling, informing the design of pilot- and full-scale treatment facilities.",
