Webb21 juli 2024 · This new AGS reactor model includes key features of full-scale AGS systems: (1) simultaneous fill-draw mode operation, (2) selective sludge removal, (3) coexistence of flocs and granules, (4) distinct settling models for flocs and granules. WebbTo achieve N removal via nitrite by suppressing NOB, other studies have used DO, pH, and ORP in aerobic granular sludge reactors (Lochmatter, Gonzalez‐Gil, & Holliger, 2013; Tao, Gao, Fu, Wu, & Ren, 2012), while DO and ABAC have been used in conventional activated sludge systems (Regmi et al., 2015, 2014) to control DO setpoint and aerobic duration.

Webb1 jan. 2012 · In this study, four full-scale activated sludge reactors, which have similar operating conditions and influent quality, were chosen to investigate the dynamic and characteristics of the MCS in activated sludge and the interaction between the MCS and influent and effluent water quality using PLFA profiling. Webb10 - Concentration of settled sludge = 8,000 mg/L: 2 - Influent suspended solids = 200 mg/L: 11 - Settled sludge specific gravity = 1.02: 3 - Influent VSS = 150 mg/L: 12 - 60 % of reactor volume will be decanted each day: 4 - Wastewater temperature = 20 °C: 13 - Liquid depth of SBR = 6.60 m: 5 - Hydraulic detention time = 24 h
WebbThe 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, treated to remove undesirable components, and then discharged. Equalization, aeration, and clarification can all be achieved using a single batch reactor. To optimize Webb18 maj 2024 · The reactor is usually configured as a fluidised bed, though the more unusual rotating cone reactor has been commercialised and the auger/screw reactors successfully demonstrated at large pilot scale.
