Effect of biomass features on oxygen transfer in Conventional Activated Sludge and Membrane BioReactor systems
2018
The present study reports the results on the comparison between the oxygen transfer efficiency in a conventional activated sludge (CAS) and membrane bioreactor (MBR) system. The oxygen transfer was evaluated by means of the oxygen transfer coefficient (kLa)20 and α-factor calculation, under different operating conditions and with different activated sludge features, including total suspended solids (TSS) concentration, extracellular polymeric substances (EPS) content and composition, sludge viscosity and size of the flocs. The (kLa)20 and α-factor showed an exponential decreasing trends with TSS in the CAS and MBR, even if it was noted that the (kLa)20 dependence on TSS was stronger in the …
Effect of long-term salinity increase on nitritation and denitritation kinetics in activated sludge and granular sludge reactors
2017
The aim of this work was to investigate the effects of moderate and drastic long-termincrease of salinity.Particularly, the study was aimed at assessing the shock effecton nitritationand denitritation kineticsof halophilic biomass inboth forms:flocculent activated sludge and granular sludge.
