Fixed film reactor denitrification
WebAbstract. Wastewater treatment systems using bio-films that grow attached to a support media are an alternative to the widely used suspended growth activated sludge process. … WebMay 1, 2016 · This finding led us to ask whether DO could also improve BDP-based denitrification in fixed-film denitrifying reactors. If the answer is yes, a convenient method could be supplied to remove NO 3 −-N from RASs. The current study was undertaken to investigate the effect of influent DO concentration on heterotrophic denitrification in …

WebA literature review furthermore suggested that the kinetic parameters for autotrophic denitrification by Thiobacillus denitrificans represent no bottleneck for its application. Initial experimental studies in fixed-film reactors were conducted with sodium sulfide and nitrate as an electron donor-acceptor couple. WebThe sequencing batch reactor (SBR) is a fill-and-draw activated sludge system for wastewater treatment. In this system, wastewater is added to a single batch reactor, …
WebThe post-treatment of effluents from anaerobic reactors is normally a mandatory step to meet the emission standards. The results presented here show the feasibility of using a new configuration of biological aerated filter (BAF) in the post-treatment of UASB reactors. The multi-stage BAF presents an anaerobic chamber (V=12.6L), followed by an aerobic … Webzanatte presented denitrification results from a fixed-film anoxic sand reactor used for drinking water treatment. The anoxic re actor was operated downflow at 20 m3/h with a nitrate loading of 0.4-1.5 kg N03-N/m3?d; nitrate removal rates, using sugar or glucose syrup as organic carbon sources, were usually greater than 95%.
