Using the activated sludge model 2d (ASM2d) to understand and predict the phosphorus accumulating organisms mechanism in enhanced biological phosphorus removal in relation to disintegrated sludge as a carbon source [PDF]
, 2012 Carbon sources are considered as one of the most important factors in the performance of enhanced biological phosphorus removal (EBPR). Disintegrated sludge (DS) can act as carbon source to increase the efficiency of EBPR.

Mechanical sludge disintegration for the production of carbon source for biological nutrient removal. [PDF]
, 2007 The primary driver for a successful biological nutrient removal is the availability of suitable carbon source, mainly in the form of volatile fatty acids (VFA). Several methods have been examined to increase the amount of VFAs in wastewater.

Effect of influent nutrient ratios and hydraulic retention time (HRT) on simultaneous phosphorus and nitrogen removal in a two-sludge sequencing batch reactor process [PDF]
, 2009 A laboratory-scale anaerobic–anoxic/nitrification sequencing batch reactor (A2N- SBR) fed with domestic wastewater was operated to examine the effect of varying ratios of influent COD/P, COD/TN and TN/P on the nutrient removal.

Removal of Sewage Nutrients by Algae [PDF]
Public Health Reports (1896-1970), 1961 EXCESSIVE enrichment, or eutrophication, of receiving waters by nutrient-rich wastes is emerging as a major water pollution problem. For some time it has been recognized that ordinary domestic sewage is a rich source of the nutrients required by phytoplankton. Inorganic nitrogen and phosphorus are the most important of these nutrients, and it is on the

Effects of Sludge Retention Times on Nutrient Removal and Nitrous Oxide Emission in Biological Nutrient Removal Processes [PDF]
International Journal of Environmental Research and Public Health, 2014 Sludge retention time (SRT) is an important factor affecting not only the performance of the nutrient removal and sludge characteristics, but also the production of secondary pollutants such as nitrous oxide (N2O) in biological nutrient removal (BNR) processes. Four laboratory-scale sequencing batch reactors (SBRs), namely, SBR5, SBR10, SBR20 and SBR40
