By Pedros, P B Onnis-Hayden, A; Tyler, Charles ABSTRACT: The purpose of this study was to investigate the nitrification and nitrogen removal from centrate produced in the dewatering process of anaerobically digested sludge, using a single- unit, single-zone submerged attached-growth bioreactor.

By Dosta, J Gali, A; El-Hadj, T Benabdallah; Mata-Alvarez, J ABSTRACT: An efficient biological treatment to treat reject water from anaerobic digestion of wastewater sludge is the SHARON denitrification process, which takes place in a chemostat reactor, where aerobic/anoxic periods are alternated under specific hydraulic retention time (HRT) and temperature conditions that favor ammonium oxidizers growth and ensure the total washout of nitrite oxidizers, achieving the biological nitrogen...
