Induction of phosphorus removal in an enhanced biological phosphorus removal bacterial population

A weak-base fibrous anion exchanger effective for rapid phosphate removal from water

“…Many techniques have been proposed for phosphate removal from water and wastewater such as iron coagulation [8][9][10], biological removal [11][12][13] and adsorption by selective adsorbents [14][15][16][17][18][19][20][21]. A feasible method is necessary for removing phosphate from water to relieve the eutrophication.…”

“…A feasible method is necessary for removing phosphate from water to relieve the eutrophication. It is reported that precipitation and biological methods are not able to take up phosphorus completely or reduce its concentration near to zero or below 10 g/L [12]. Several researchers also proposed ligand exchange adsorbents; these are cation exchange and chelating resins on which hard Lewis acid cations, such as Zr(IV), Fe(III), Al(III), and Mo(VI), are loaded [22][23][24][25][26][27].…”

Effect of Long Sludge Retention Time on Biological Phosphorus Removal in A2/O Process

“…In analysis of mass balance in A2/O process, the total phosphate content in dry waste sludge ratio was generally assumed as 3% (Randall, et al, 1997;. Moreover, the ratio was usually considered as a constant when the operation parameters were changed.…”

Assessment of crude glycerol for Enhanced Biological Phosphorus Removal: Stability and role of long chain fatty acids

“…Methanol is the most common external carbon source used for denitrification, but its utilization for EBPR has conducted to numerous failures (Puig et al, 2008;Randall et al, 1997b) before being successfully reported in a recent work (Tayà et al, 2013). PAO-enriched biomass in a conventional anaerobic-aerobic sequencing batch reactor (SBR) was unable to survive using methanol as sole carbon source when a direct replacement for propionic acid in the work of Tayà et al (2013).…”
